The principle of indifference states that in the absence of any relevant evidence, a rational agent will distribute their credence equally among all the possible outcomes under consideration. Despite its intuitive plausibility, PI famously falls prey to paradox, and so is widely rejected as a principle of ideal rationality. In this article, I present a novel rehabilitation of PI in terms of the epistemology of comparative confidence judgments. In particular, I consider two natural comparative reformulations of PI and argue (...) that while one of them prescribes the adoption of patently irrational epistemic states, the other provides a consistent formulation of PI that overcomes the most salient limitations of existing formulations.

Many theorists have proposed that we can use the principle of indifference to defeat the inductive sceptic. But any such theorist must confront the objection that different ways of applying the principle of indifference lead to incompatible probability assignments. Huemer offers the explanatory priority proviso as a strategy for overcoming this objection. With this proposal, Huemer claims that we can defend induction in a way that is not question-begging against the sceptic. But in this article, I argue that (...) the opposite is true: if anything, Huemer’s use of the principle of indifference supports the rationality of inductive scepticism. (shrink)

Sometimes different partitions of the same space each seem to divide that space into propositions that call for equal epistemic treatment. Famously, equal treatment in the form of equal point-valued credence leads to incoherence. Some have argued that equal treatment in the form of equal interval-valued credence solves the puzzle. This paper shows that, once we rule out intervals with extreme endpoints, this proposal also leads to incoherence.

The classical theory of probability has long been abandoned and is seen by most philosophers as a non-contender—a mere precursor to newer and better theories. In this paper I argue that this is a mistake. The main reasons for its rejection—all related to the notorious principle of indifference—are that it is circular, of limited applicability, inconsistent, and dependent upon unjustified empirical assumptions. I argue that none of these claims is true and that the classical theory remains to be refuted.

The _Principle of Indifference_ was once regarded as a linchpin of probabilistic reasoning, but has now fallen into disrepute as a result of the so-called _problem of multiple of partitions_. In ‘Evidential symmetry and mushy credence’ Roger White suggests that we have been too quick to jettison this principle and argues that the problem of multiple partitions rests on a mistake. In this paper I will criticise White’s attempt to revive POI. In so doing, I will argue that what underlies (...) the problem of multiple partitions is a fundamental tension between POI and the very idea of _evidential incomparability_. (shrink)

The principle of indifference is supposed to suffice for the rational assignation of probabilities to possibilities. Bertrand advances a probability problem, now known as his paradox, to which the principle is supposed to apply; yet, just because the problem is ill‐posed in a technical sense, applying it leads to a contradiction. Examining an ambiguity in the notion of an ill‐posed problem shows that there are precisely two strategies for resolving the paradox: the distinction strategy and the well‐posing strategy. The (...) main contenders for resolving the paradox, Marinoff and Jaynes, offer solutions which exemplify these two strategies. I show that Marinoff’s attempt at the distinction strategy fails, and I offer a general refutation of this strategy. The situation for the well‐posing strategy is more complex. Careful formulation of the paradox within measure theory shows that one of Bertrand’s original three options can be ruled out but also shows that piecemeal attempts at the well‐posing strategy will not succeed. What is required is an appeal to general principle. I show that Jaynes’s use of such a principle, the symmetry requirement, fails to resolve the paradox; that a notion of metaindifference also fails; and that, while the well‐posing strategy may not be conclusively refutable, there is no reason to think that it can succeed. So the current situation is this. The failure of Marinoff’s and Jaynes’s solutions means that the paradox remains unresolved, and of the only two strategies for resolution, one is refuted and we have no reason to think the other will succeed. Consequently, Bertrand’s paradox continues to stand in refutation of the principle of indifference. (shrink)

Events between which we have no epistemic reason to discriminate have equal epistemic probabilities. Bertrand’s chord paradox, however, appears to show this to be false, and thereby poses a general threat to probabilities for continuum sized state spaces. Articulating the nature of such spaces involves some deep mathematics and that is perhaps why the recent literature on Bertrand’s Paradox has been almost entirely from mathematicians and physicists, who have often deployed elegant mathematics of considerable sophistication. At the same time, the (...) philosophy of probability has been left out. In particular, left out entirely are the philosophical ground of the principle of indifference, the nature of the principle itself, the stringent constraint this places on the mathematical representation of the principle needed for its application to continuum sized event spaces, and what these entail for rigour in developing the paradox itself. This book puts the philosophy and its entailments back in and in so doing casts a new light on the paradox, giving original analyses of the paradox, its possible solutions, the source of the paradox, the philosophical errors we make in attempting to solve it and what the paradox proves for the philosophy of probability. The book finishes with the author’s proposed solution—a solution in the spirit of Bertrand’s, indeed—in which an epistemic principle more general than the principle of indifference offers a principled restriction of the domain of the principle of indifference.

Many philosophers have been attracted to a restricted version of the principle of indifference in the case of self‐locating belief. Roughly speaking, this principle states that, within any given possible world, one should be indifferent between different hypotheses concerning who one is within that possible world, so long as those hypotheses are compatible with one's evidence. My first goal is to defend a more precise version of this principle. After responding to several existing criticisms of such a principle, I (...) argue that existing formulations of the principle are crucially ambiguous, and I go on to defend a particular disambiguation of the principle. According to the disambiguation I defend, how we should apply this restricted principle of indifference sensitively depends on our background metaphysical beliefs. My second goal is to apply this disambiguated principle to classical skeptical problems in epistemology. In particular, I argue that Eternalism threatens to lead us to external world skepticism, and Modal Realism threatens to lead us to inductive skepticism. (shrink)

Traditionally, it has been thought that, assuming other conditions are satisfied, your action must be morally worthy or good if you are acting solely from good motives. There is a lively dispute as to which motives are good, but whichever motives are good, acting solely from good motives is not always good and can even be bad on the whole. We may act rightly from a good motive while being indifferent to what matters most. Indifference, I argue, can make (...) our actions less than ideally good and at times even bad. Traditional theories, however, cannot accommodate cases of indifference by assuming absent and ineffective motives can never make a difference to an action’s moral value. Absent as well as ineffective motives can make an action less good and at times even bad. To accommodate this, we need to adopt a proportionality principle in assessing an action. An action is made good to a degree in proportion to the goodness of its effective motives. But an action is also made bad to a degree in proportion to the disproportion it exhibits through its whole set of relevant motives including not only effective motives but also absent as well as ineffective ones.

Roger White (2015) sketches an ingenious new solution to the problem of induction. He argues from the principle of indifference for the conclusion that the world is more likely to be induction- friendly than induction-unfriendly. But there is reason to be skeptical about the proposed indifference-based vindication of induction. It can be shown that, in the crucial test cases White concentrates on, the assumption of indifference renders induction no more accurate than random guessing. After discussing this result, (...) the paper explains why the indifference-based argument seemed so compelling, despite ultimately being unsound. (shrink)

An indifference principle says that your credences should be distributed uniformly over each of the possibilities you recognise. A chance deference principle says that your credences should be aligned with the chances. My thesis is that, if we are anti-Humeans about chance, then these two principles are incompatible. Anti-Humeans think that it is possible for the actual frequencies to depart from the chances. So long as you recognise possibilities like this, you cannot both spread your credences evenly and (...) defer to the chances. I discuss some weaker forms of indifference which will allow anti-Humeans to defer to the chances. (shrink)

How do you make decisions under ignorance? That is, how do you decide when you lack subjective probabilities for some of your options’ possible outcomes? One answer is that you follow the Laplace Rule: you assign an equal probability to each state of nature for which you lack a subjective probability (that is, you use the Principle of Indifference) and then you maximize expected utility. The most influential objection to the Laplace Rule is that it is sensitive to the (...) individuation of states of nature. This sensitivity is problematic because the individuation of states seems arbitrary. In this paper, however, I argue that this objection proves too much. I argue that all plausible rules for decisions under ignorance are sensitive to the individuation of states of nature. (shrink)

If the laws of nature are as the Humean believes, it is an unexplained cosmic coincidence that the actual Humean mosaic is as extremely regular as it is. This is a strong and well-known objection to the Humean account of laws. Yet, as reasonable as this objection may seem, it is nowadays sometimes dismissed. The reason: its unjustified implicit assignment of equiprobability to each possible Humean mosaic; that is, its assumption of the principle of indifference, which has been attacked (...) on many grounds ever since it was first proposed. In place of equiprobability, recent formal models represent the doxastic state of total ignorance as suspension of judgment. In this paper I revisit the cosmic coincidence objection to Humean laws by assessing which doxastic state we should endorse. By focusing on specific features of our scenario I conclude that suspending judgment results in an unnecessarily weak doxastic state. First, I point out that recent literature in epistemology has provided independent justifications of the principle of indifference. Second, given that the argument is framed within a Humean metaphysics, it turns out that we are warranted to appeal to these justifications and assign a uniform and additive credence distribution among Humean mosaics. This leads us to conclude that, contrary to widespread opinion, we should not dismiss the cosmic coincidence objection to the Humean account of laws. (shrink)

Why does God allow evil? One hypothesis is that God desires the existence and activity of free creatures but He was unable to create a world with such creatures and such activity without also allowing evil. If Molinism is true, what probability should be assigned to this hypothesis? Some philosophers claim that a low probability should be assigned because there are an infinite number of possible people and because we have no reason to suppose that such creatures will choose one (...) way rather than another. Arguments like this depend on the principle of indifference. But that principle is rejected by most philosophers of probability. Some philosophers claim that a low probability should be assigned because doing otherwise violates intuitions about freewill. But such arguments can be addressed through strategies commonly employed to defend theories with counterintuitive results across ethics and metaphysics. (shrink)

Experimental results on the Ellsberg paradox typically reveal behavior that is commonly interpreted as ambiguity aversion. The experiments reported in the current paper find the objective probabilities for drawing a red ball that make subjects indifferent between various risky and uncertain Ellsberg bets. They allow us to examine the predictive power of alternative principles of choice under uncertainty, including the objective maximin and Hurwicz criteria, the sure-thing principle, and the principle of insufficient reason. Contrary to our expectations, the principle (...) of insufficient reason performed substantially better than rival theories in our experiment, with ambiguity aversion appearing only as a secondary phenomenon.

I propose the notion of ‘epistemic sanity’, a property of parsimony between the holding of true but not false beliefs and the consideration of our cognitive limitations. Where ‘alethic value’ is the epistemic value of holding true but not false beliefs, the ‘alethic potential’ of an agent is the amount of extra alethic value that she is expected to achieve, given her current environment, beliefs, and reasoning skills. Epistemic sanity would be related to the holding of (true or false) beliefs (...) that increase the agent's alethic potential (relevant beliefs) but not of beliefs that decrease it (this is related to cognitive parsimony). Suspension of judgment, forgetting, and clutter avoidance are the main contributors to an agent's epistemic sanity, where this paper focuses on suspension. I argue that rational suspension favors the holding of true and relevant beliefs, which is not the case for the extremes of opinionation (no suspension) and skepticism (general suspension). In the absence of evidence, opinionated agents are often forced to rely on principles such as the principle of indifference, but suspension dominates indifference in terms of alethic value in some conditions. A rational agent would only find it beneficial to adopt skepticism if she considers herself to be an anti-expert about her entire agenda, but then ‘flipping’ beliefs maximizes expected alethic value in relation to skepticism. The study of epistemic sanity results in an ‘impure’ veritism, which can deal with some limitations of veritism (e.g., explaining the existence of false but relevant beliefs). (shrink)

We argue that a modified version of Mill’s method of agreement can strongly confirm causal generalizations. This mode of causal inference implicates the explanatory virtues of mechanism, analogy, consilience, and simplicity, and we identify it as a species of Inference to the Best Explanation (IBE). Since rational causal inference provides normative guidance, IBE is not a heuristic for Bayesian rationality. We give it an objective Bayesian formalization, one that has no need of principles of indifference and yields responses (...) to the Voltaire objection, van Fraassen’s Bad Lot objection, and John Norton’s recent objection to IBE.

An important suggestion of objective Bayesians is that the maximum entropy principle can replace a principle which is known to get into paradoxical difficulties: the principle of indifference. No one has previously determined whether the maximum entropy principle is better able to solve Bertrand’s chord paradox than the principle of indifference. In this paper I show that it is not. Additionally, the course of the analysis brings to light a new paradox, a revenge paradox of the chords, that (...) is unique to the maximum entropy principle. (shrink)

My first goal is to motivate a distinctively metaphysical approach to the problem of induction. I argue that there is a precise sense in which the only way that orthodox Humean and non-Humean views can justify induction is by appealing to extremely strong and unmotivated probabilistic biases. My second goal is to sketch what such a metaphysical approach could possibly look like. After sketching such an approach, I consider a toy case that illustrates the way in which such a metaphysics (...) can help us make progress on the problem of induction. (shrink)

English translation of an article originally published in French in Liber Amicorum Pascal Engel, J. Dutant, G. Fassio & A. Meylan (eds.), University of Geneva, 2014, pp. 581-608. In what follows, I strive to present the elements of a philosophical doctrine, which can be defined as dialectical contextualism. I proceed first to define the elements of this doctrine: dualities and polar contraries, the principle of dialectical indifference and the one-sidedness bias. I emphasize then the special importance of this doctrine (...) in one specific field of meta-philosophy: the methodology for solving philosophical paradoxes. Finally, I describe several applications of this methodology on the following paradoxes: Hempel's paradox, the surprise examination paradox and the Doomsday Argument. (shrink)

Copernican reasoning involves considering ourselves, in the absence of other information, to be randomly selected members of a reference class. Consider the reference class intelligent observers. If there are extraterrestrial intelligences (ETIs), taking ourselves to be randomly selected intelligent observers leads to the conclusion that it is likely the Earth has a larger population size than the typical planet inhabited by intelligent life, for the same reason that a randomly selected human is likely to come from a more populous country. (...) The astrophysicist Fergus Simpson contends that this reasoning supports the claims that the typical planet inhabited by ETIs is smaller than Earth (radius about 5,000km; cf. Earth's radius = 6,371km) and that the typical ETI is significantly larger than us about 314kg, the size of an adult male grizzly bear). Simpson's applications of Copernican reasoning are novel and exciting. They should be of interest to philosophers concerned with Richard Gott's delta t argument, the N=1 problem in astrobiology, limited principles of indifference, and probabilistic epistemology in general. While we agree with Simpson about the qualitative direction of his conclusions, we take issue with his presentation of precise quantitative results because his methods (1) display bias, (2) ignore other variables contributing to population size, (3) commit an equivocation, and (4) conceal their dependence on arbitrary assumptions.

Abstract -/- The indistinction between repose and uniform movement exposed in the principle of inertia marks one of the most famous dissertations: the discussion between Newton and Leibniz. Through their respective conceptions of space, both seek to solve the problem of indistinction. The relational space of Leibniz, supported by the principle of sufficient reason and the identity of indiscernibles leads to the kinematic solution of the problem of inertia. The objective of this paper is to show the contribution of Leibniz, (...) in terms of relations of order, by distinguishing between equality by identity and equality by equivalence. Under a philosophical approach we link identity, equivalence and equality as relations of order with the indiscernibility between different states of movement. We expose first the principle of sufficient reason and the identity of indiscernibles. Under Bernoulli's principle of indifference, we argue that we distinguish between equality in abstract and equality in concrete. As a third part, we present the relationship between the identity of the indiscernibles and the predicate of equality under logical analysis. Finally we present the conclusions. -/- . (shrink)

The theater principle personifies the universe and all natural as a live performance theater run by an unknown showrunner and indifferent audience members.

And the fortunate circumstances of being a conscious being.

An important line of response to scepticism appeals to the best explanation. But anti-sceptics have not engaged much with work on explanation in the philosophy of science. I plan to investigate whether plausible assumptions about best explanations really do favour anti-scepticism. I will argue that there are ways of constructing sceptical hypotheses in which the assumptions do favour anti-scepticism, but the size of the support for anti-scepticism is small.

The Pareto principle states that if the members of society express the same preference judgment between two options, this judgment is compelling for society. A building block of normative economics and social choice theory, and often borrowed by contemporary political philosophy, the principle has rarely been subjected to philosophical criticism. The paper objects to it on the ground that it indifferently applies to those cases in which the individuals agree on both their expressed preferences and their reasons for entertaining them, (...) and those cases in which they agree on their expressed preferences, while differing on their reasons. The latter are cases of "spurious unanimity", and it is normatively inappropriate, or so the paper argues, to defend unanimity preservation at the social level for them, so the Pareto principle is formulated much too broadly. The objection seems especially powerful when the principle is applied in an ex ante context of uncertainty, in which individuals can disagree on both their probabilities and utilities, and nonetheless agree on their preferences over prospects.

In a recent article, Adam Elga outlines a strategy for “Defeating Dr Evil with Self-Locating Belief”. The strategy relies on an indifference principle that is not up to the task. In general, there are two things to dislike about indifference principles: adopting one normally means confusing risk for uncertainty, and they tend to lead to incoherent views in some ‘paradoxical’ situations. I argue that both kinds of objection can be levelled against Elga’s indifference principle. There are (...) also some difficulties with the concept of evidence that Elga uses, and these create further difficulties for the principle. (shrink)

In attempting to form rational personal probabilities by direct inference, it is usually assumed that one should prefer frequency information concerning more specific reference classes. While the preceding assumption is intuitively plausible, little energy has been expended in explaining why it should be accepted. In the present article, I address this omission by showing that, among the principled policies that may be used in setting one’s personal probabilities, the policy of making direct inferences with a preference for frequency information for (...) more specific reference classes yields personal probabilities whose accuracy is optimal, according to all proper scoring rules, in situations where all of the relevant frequency information is point-valued. Assuming that frequency information for narrower reference classes is preferred, when the relevant frequency statements are point-valued, a dilemma arises when choosing whether to make a direct inference based upon relatively precise-valued frequency information for a broad reference class, R, or upon relatively imprecise-valued frequency information for a more specific reference class, R*. I address such cases, by showing that it is often possible to make a precise-valued frequency judgment regarding R* based on precise-valued frequency information for R, using standard principles of direct inference. Having made such a frequency judgment, the dilemma of choosing between and is removed, and one may proceed by using the precise-valued frequency estimate for the more specific reference class as a premise for direct inference.

One of the most difficult problems in the foundations of physics is what gives rise to the arrow of time. Since the fundamental dynamical laws of physics are (essentially) symmetric in time, the explanation for time's arrow must come from elsewhere. A promising explanation introduces a special cosmological initial condition, now called the Past Hypothesis: the universe started in a low-entropy state. Unfortunately, in a universe where there are many copies of us (in the distant ''past'' or the distant ''future''), (...) the Past Hypothesis is not enough; we also need to postulate self-locating (de se) probabilities. However, I show that we can similarly use self-locating probabilities to strengthen its rival---the Fluctuation Hypothesis, leading to in-principle empirical underdetermination and radical epistemological skepticism. The underdetermination is robust in the sense that it is not resolved by the usual appeal to 'empirical coherence' or 'simplicity.' That is a serious problem for the vision of providing a completely scientific explanation of time's arrow. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Philosophy and Literature 26.1 (2002) 207-215 [Access article in PDF] Notes and Fragments Poetics of Sentimentality Rick Anthony Furtak IN HIS MAJOR WORK, The Passions, Robert Solomon argues that emotions are judgments. 1 Through a series of persuasive examples, he shows that emotions are best understood as mental states which involve certain beliefs about the world. This means that every emotion has an object: if I am angry at (...) John for stealing my car, the object of my anger is the fact (or what I take to be a fact) that my car has been stolen by John. If I find out that this is not the case, that my car has not even left the garage, then my anger should vanish along with its justification. 2 The key point here is that anger, like any other emotion, may be reasonable or inappropriate depending on the situation. If there is nothing to be angry about, then it would be irrational for me to cultivate anger simply because I enjoy having this particular emotion. In general, emotional responses are cognitively flawed whenever they are at odds with the properties of their objects. If we want our judgments to be realistic and not delusional, then we must avoid this kind of error.It is curious, then, that Solomon has written an essay in which he categorically declares that "there is nothing wrong with sentimentality." 3 For it would appear that his theory of emotion provides precisely the terms needed in order to specify what is wrong with it. If emotions are judgments, then "sentimentality" ought to be an important critical term to designate the habit of having emotions that involve either impaired or mistaken judgment. Nevertheless, Solomon is willing to defend any and every episode of tender emotion, of the kind associated with the [End Page 207] death of Little Nell in The Old Curiosity Shop (S, p. 240). He suggests that the more we can muster up this sort of response to literature or life, the better. What he seeks to encourage, in other words, is what Hume would call "delicacy" of (aesthetic) taste and of (ethical) passion. 4 But while Hume acknowledges that sensitivity to beauty and to ugliness are two sides of the same coin, such that anyone who is susceptible to lively enjoyments is also liable to undergo pungent sorrows, Solomon wants to promote only the tender aspect of emotion.On the principle of passionate maximization, it is good if I can be tenderly affected by a poem—any poem! The problem with such crass emotion-stoking is that it precludes the possibility of distinguishing between, for instance, the two stanzas below. Both are by Wilfred Owen: the first was written in 1914 and the second in 1918. 5 I O meet it is and passing sweet To live in peace with others, But sweeter still and far more meet To die in war for brothers. II Bent double, like old beggars under sacks, Knock-kneed, coughing like hags, we cursed through sludge, Till on the haunting flares we turned our backs And towards our distant rest began to trudge. Men marched asleep. Many had lost their boots But limped on, blood-shod. All went lame; all blind; Drunk with fatigue; deaf even to the hoots Of tired, outstripped Five-Nines that dropped behind. Only if emotions did not involve rational judgment could a person's passionate response to these two stanzas be a matter of indifference. But it seems that, on the contrary, an essential component of understanding them is recognizing that they express irreconcilable cognitive attitudes. The tone of the 1918 stanza is strikingly different from that of the earlier one, even though they share roughly the same topic. The latter stanza is stark and ominous, and filled with vivid detail; the one from 1914 is sweet and vague. Clearly, we might describe the earlier of the two as "sentimental"—the question is, what kind of judgment does [End Page 208] it involve? I suggest that its insipid jingles endorse the view that war is a delightful opportunity to nurture brotherhood and gain... (shrink)

Sometimes we learn what the world is like, and sometimes we learn where in the world we are. Are there any interesting differences between the two kinds of cases?

German idealism stems in large part from Fichte’s response to a dilemma involving the concepts of pantheism, freedom and time: either time is the form of the determination of modes of substance, as held by a pantheistic or ‘dogmatic’ person, or the form of acts generated by human freedom, as held by an idealistic person. Fichte solves the dilemma by refuting dogmatism and deducing time from idealism’s first principle. But his diagnosis is more portentous: by casting the lemmas in terms (...) of person-types, he unintentionally invites Schelling’s philosophical rethinking of personality. In his middle period, Schelling argues for the consistency of the concepts of pantheism, freedom and time, claiming that it depends on a ‘good’ as opposed to ‘evil’ personality. However, since on his view personality is an absolute or originally undecided capacity for good and evil, the trio’s consistency is entirely contingent. In §1, I trace Fichte’s resolution of the dilemma. In §§2-3, I reconstruct Schelling’s arguments for consistency from the Freiheitsschrift and Weltalter, texts written just a few years apart. In §4, I allay a Kantian worry that this consistency relies problematically on the liberty of indifference or Willkür. (shrink)

This dialogue builds on a previous critique that highlights a methodological paradox in the empirical application of probability theory. In the earlier work, it was suggested that while probability is mathematically sound, conceptual challenges arise when it is used to model real-world uncertainty. In this dialogue, Laplace, a proponent of classical probability, and Incredulus, a philosophical skeptic, engage in a thoughtful examination of these issues. Their inquiry explores the interplay between logic, probability, and empirical observation, raising questions about how past (...) experiences shape our understanding of possible outcomes and the limits this may impose on probabilistic reasoning.

Modern science only studies that which is immediately given to our senses - that which we call matter. But there would be no such thing as science if there were only matter or existence. Science requires that in addition to existence there be cognition of existence, or consciousness. Without consciousness of existence, science would never come into being. Thus we must admit that at least two features of reality are necessary for scientific knowledge - (1) existence or being and (2) (...) consciousness of existence. But there is still a third feature of reality upon which the first two are dependent. We can call this satisfaction or the fulfillment of being. If there were mere existence without consciousness of existence, we could say nothing about such existence. But even mere consciousness of existence would also be a passive, indifferent existence. It is only because we seek satisfaction, fulfillment, and enjoyment that we create science, philosophy, culture, religion, etc. If there were no need for fulfillment or satisfaction then all these activities would never arise. There would be no need, no desire, no lack or negativity, and therefore non-differentiation. Thus, it is this fundamental quality that characterizes life: it seeks satisfaction or fulfillment. It is from this basic quality that all activity arises. We can call this the Ultimate Principle of Reality. By inquiring into where this principle comes from and why it exists, we will be able to understand how to achieve the greatest satisfaction and happiness. It is this type of inquiry that produces what is called the science of happiness. (shrink)

This chapter presents the formalist account of the moral status of an artwork as an aesthetically significant and autonomous form, with due emphasis on the Anglo-American art-for-art’s-sake aesthetic, as it developed between 1870 and 1960. The author shows that the formalist art-is-above-morals approach is a substantive moral stance in itself. Formalist aesthetics is usually presented in the literature as evincing a purist indifference to ethics, construing moral properties as external to art, in opposition to the internal pure properties of (...) art’s composition. The chapter demonstrates that this is a misrepresentation of the complex formalist prescriptive idea of the relations between art and ethics. Through its autonomy and imperviousness to external co-opting—which is accomplished by due focus on aesthetic form—art on the formalist account is held to be a paradigm of the liberalist principles of individual freedom and self-fulfillment, thus an inherent means to the good.

The object of the study is to introduce an innovative approach to the long-lasting theoretical discussion about the meaning and extent of political liberty in a modern democratic society. The suggested way to explain why the democratic political order as such might give rise to considerable challenges for political liberty introduces the classical virtue of courage as a possible key explanatory factor underlying the major tensions that emerge between democracy and liberty. Such approach provides some new insights into the debate (...) about the origins, limits, and political perspectives of modern democracies. The analysis starts by conceptualizing modern democracy as a political form which expresses a specific ethical idea about the natural equality of people. Generally, it means that egalitarianism is the founding idea and moral purpose of a democratic political system, which tends to develop into a modern type of representative government and civil society. The second part of our analysis emphasizes the fact that liberty is by nature a political fact achieved only by practical participation of an individual in public life, and which cannot be reduced to formal, legal, economic or moral categories. Liberty, being a principle of public action, requires the capacity of a person to risk his personal wealth and safety for the sake of the common good. The third part of the analysis explains the crucial importance of the virtue of courage to the whole political life, as it is an ethical idea which aims at building such a character of a person that is capable and motivated to live an active public life. It is the virtue of courage that makes an individual morally fit and eager to practice liberty, as well as ready to defend it against any acts of despotism. Finally, the analysis assesses the diminishing role of courage due to the egalitarian public order of a democracy, resulting in adverse effects on liberty. The conclusions of the article highlight several points which are noted below. In a democratic society, courage loses its status as a virtue; thus, individuals become less capable and less motivated to live an active public life. Democracy rests on the principle that implies establishing and protecting the equality of its citizens, while the virtue of courage expresses an implicit distaste for egalitarianism and encourages people to strive for an ethically superior status than that of all the rest, i.e. it makes a clear hierarchical distinction between cowards, conformists, and heroes. That’s why democracy banishes courage from its equality favoring public life, depriving it of its ethical status. The decline of this virtue makes the practice of liberty more complicated as individuals lose interest in risking their private wealth and safety for the sake of the common good. The diminishing capacity and interest of citizens in democracy to live an active public life, while giving preference to social equality which requires no personal effort, is a major problem for political liberty. As people become indifferent to the pursuit of the common good, liberty becomes inactive, and the political community becomes less immune to various manifestations of despotism. (shrink)

This is a defense of Rawls against recent criticism, ironically my own, though it is also a critique insofar as it addresses a problem that Rawls never does. As a defense, it is not a retraction of the original charges. As a critique, it is not more of the same op-position. In either capacity, it is not an afterthought. The charges were conceived from the outset with a specific solution in mind, which would have been too distracting to pursue in (...) the same article. This is that solution. It also highlights the problem. The original charges were that Rawls’s decision procedure for ethics does not justify his own moral principles, namely his principles of justice, and that the underlying problem may well keep the decision procedure from justifying any moral principles whatsoever, or at least any normatively useful ones. The underlying problem was, and still is, the model’s inherent universalism, which is built into the decision procedure through design specifications precluding relativism, yet only at the cost of limiting the relevant moral principles to generalities that are already widely accepted, thereby render-ing the procedure at best redundant and very likely vacuous as an ethical justification model. These difficulties are manifested in the work of Rawls as the dogmatism of champi-oning a distinctive conception of justice, a liberal one as he himself calls it, through a justification model that is too universalistic to permit such a bias and possibly also too universalistic to permit any substantive conclusions at all. The solution contemplated here is to position the decision procedure as a dynamic justification model responsive to moral progress, as opposed to a static one indifferent to such progress and equally open to all moral input, thus removing the inconsistency between the universalistic design and any distinctive or controversial principles, including the ones Rawls himself recommends, so long as they are consistent with moral progress.

In this article, three concepts that constitute the pillars of sciences, namely the subject, principle and problem, will be examined relying on Avicenna’s (d. 428/1037) book of Burhān. These three concepts, which generally determine the scope of scientific research and the principles on which it should be based, were introduced systematically for the first time by Aristotle (d. 322 BC) in the history of thought. Through these concepts, philosophical sciences could be distinguished from one another and it became possible (...) for each science to examine specific parts of existence. This distinction, which was also adopted by the scholars of Islamic thought, has presented such an integrity that neither philosophical disciplines nor religious sciences could remain indifferent. As a matter of fact, especially in the later period of theologicians, the information was considered as science only if it was based on these three concepts. Therefore, it can be asserted that these three concepts were considered as the measure of scientific activity, first by peripatetic philosophy and later by other disciplines. (shrink)

This paper examines the debate between permissive and impermissive forms of Bayesianism. It briefly discusses some considerations that might be offered by both sides of the debate, and then replies to some new arguments in favor of impermissivism offered by Roger White. First, it argues that White’s (Oxford studies in epistemology, vol 3. Oxford University Press, Oxford, pp 161–186, 2010) defense of Indifference Principles is unsuccessful. Second, it contends that White’s (Philos Perspect 19:445–459, 2005) arguments against permissive views (...) do not succeed. (shrink)

This paper asks when a natural disease kind is truly 'reactive' and when it is merely associated with a corresponding social kind. I begin with a permissive account of real kinds and their structure, distinguishing natural kinds, indifferent kinds and reactive kinds as varieties of real kind characterised by super-explanatory properties. I then situate disease kinds within this framework, arguing that many disease kinds prima facie are both natural and reactive. I proceed to distinguish ‘simple dependence’, ‘secondary dependence’ and ‘essential (...) dependence’ between a natural kind and its classification, and argue that a natural kind is only really reactive, in an important sense, under conditions of essential dependence. On this basis, I offer a principled hypothesis for why psychiatric kinds tend to be more metaphysically unstable than paradigm somatic disease kinds. (shrink)

In this critical notice, I focus my attention on the chapters that deal with the explanationist response to skepticism.

Let’s say that you regard two things as on a par when you don’t prefer one to other and aren’t indifferent between them. What does rationality require of you when choosing between risky options whose outcomes you regard as on a par? According to Prospectism, you are required to choose the option with the best prospects, where an option’s prospects is a probability-distribution over its potential outcomes. In this paper, I argue that Prospectism violates a dominance principle—which I call The (...) Principle of Predominance—because it sometimes requires you to do something that’s no better than the alternatives and might be worse. I argue that this undermines the strongest argument that’s been given in favor of Prospectism. (shrink)

This paper examines John Rawls' renowned theory of justice, which outlines two principles of justice and their respective significance. It explores how Rawls' notion of equality aligns with the philosophical concept of equity, emphasizing that his call for citizen equality inherently incorporates fairness. Additionally, the paper discusses the application of Rawls' "Difference Principle" to India's reservation policy. Rawls' principles, which aim to support the worst-off in society, are reflected in India's system of reservations for marginalized groups, including backward (...) classes and differently-abled individuals, to promote equitable opportunities. However, the paper cautions that excessive reservations could limit opportunities for more privileged groups. Ultimately, it is argued that Rawls' concept of social justice has contributed to the promotion of social justice in India. (shrink)

The ‘black box’ in Stoic axiology refers to the mysterious connection between the input of Stoic deliberation (reasons generated by the value of indifferents) and the output (appropriate actions). In this paper, I peer into the black box by drawing an analogy between Stoic and Kantian axiology. The value and disvalue of indifferents is intrinsic, but conditional. An extrinsic condition on the value of a token indifferent is that one's selection of that indifferent is sanctioned by context-relative ethical principles. (...) The value of an indifferent that does not meet this condition is normatively silenced, such that it fails to constitute a reason for action. (shrink)

A debate about whether all children are entitled to an “equal” or an “adequate” education has been waged at the forefront of school finance policy for decades. In an era of budget deficits and harsh cuts in public education, I submit that it is time to move on. Equality of educational opportunity has been thought to require equal spending per pupil or spending adjusted to the needs of differently situated children. Adequacy has been understood as a level of spending sufficient (...) to satisfy some absolute, rather than relative, educational threshold. In practice, however, many courts interpreting their state’s constitutional obligations have fused the equality and adequacy theories. Certain federal laws express principles of both doctrines. And gradually, more advocates and scholars have come to endorse hybrid equality-adequacy approaches. Still, the debate persists over seemingly intractable conceptual precepts and their political and legal ramifications. Tracking the philosophical origins and evolution of equality and adequacy as legal doctrines, I explain the significance of their points of convergence and argue that the few points of divergence are untenable in practice. Equality of educational opportunity should not be interpret-ed as pursuing equal chances for educational achievement for all children, because that ideal is infeasible. Nor should educational adequacy be interpreted as completely indifferent to objectionable inequalities that can be feasibly curtailed. Properly conceived, equality and adequacy are not merely congruent but reciprocal. That is, children are owed an education that is adequately equal and equally adequate. (shrink)

The key assumption behind evolutionary epistemology is that animals are active learners or ‘knowers’. In the present study, I updated the concept of natural learning, developed by Henry Plotkin and John Odling-Smee, by expanding it from the animal-only territory to the biosphere-as-a-whole territory. In the new interpretation of natural learning the concept of biological information, guided by Peter Corning’s concept of “control information”, becomes the ‘glue’ holding the organism–environment interactions together. The control information guides biological systems, from bacteria to ecosystems, (...) in the process of natural learning executed by the universal algorithm. This algorithm, summarized by the acronym IGPT (information-gain-process-translate) incorporates natural cognitive methods including sensing/perception, memory, communication, and decision-making. Finally, the biosphere becomes the distributed network of communicative interactions between biological systems termed the interactome. The concept of interactome is based on Gregory Bateson’s natural epistemology known as the “ecology of mind”. Mimicking Bateson’s approach, the interactome may also be designated “physiology of mind”—the principle behind regulating the biosphere homeostasis. (shrink)

This article explores the cultural contexts in which three-dimensional imaging has been developed, disseminated and used. It surveys the diverse technologies and intellectual domains that have contributed to spatial imaging, and argues that it is an important example of an interdisciplinary subject. Over the past century-and-a-half, specialists from distinct fields have devised explanations and systems for the experience of 3-D imagery. Successive audiences have found these visual experiences compelling, adapting quickly to new technical possibilities and seeking new ones. These complementary (...) interests, and their distinct perspectives, have co-evolved in lock-step. A driver for this evolution is visual culture, which has grown to value and demand the spectacular. As a result, professional and popular engagements with 3-D have had periods of both popularity and indifference, and cultural consensus has proven to be ephemeral. (shrink)

The purpose of this paper is to explain and discuss Leibniz’s main objections to the Molinist-Suárezian voluntarist (libertarian) conception of freedom, i.e., the conception involving the supposition of “freedom of indifference” of the will to make contrary choices in exactly the same circumstances. Leibniz’s main objections to the voluntarist conception are the following: (i) it violates the Principle of Sufficient Reason; (ii) it is based on a mistaken picture of the nature of the will.

We start by presenting three different views that jointly imply that every person has many conscious beings in their immediate vicinity, and that the number greatly varies from person to person. We then present and assess an argument to the conclusion that how confident someone should be in these views should sensitively depend on how massive they happen to be. According to the argument, sometimes irreducibly de se observations can be powerful evidence for or against believing in metaphysical theories.

According to the Principle of Sufficient Reason (henceforth ‘PSR’), everything has an explanation or sufficient reason. This paper addresses three questions. First, how continuous is the contemporary notion of grounding with the notion of sufficient reason endorsed by Spinoza, Leibniz, and other rationalists? In particular, does a PSR formulated in terms of ground retain the intuitive pull and power of the PSR endorsed by the rationalists? Second, to what extent can the PSR avoid the formidable traditional objections levelled against it (...) if it is formulated in terms of ground? And finally, how might historical discussion of the PSR shed light on the contemporary notion of grounding? (shrink)
