Abstract Under the influence of Hilary Putnam’s collapse of the fact/value dichotomy, a resurging approach that challenges the movements of American pragmatism and discourse ethics, I tease out in the first section of my paper the demand for the warranted assertibility hypothesis in Putnam’s sense that may be possible, relying on moral realism to get rid of ‘rampant Platonism’. Tracing back to ‘communicative action’ or the Habermasian way that puts forward the reciprocal understanding of discourse instigates the (...) idea of life-world as composed of ‘culturally transmitted and linguistically organized stock of interpretative patterns’, this section looks for whether Habermas’ psychoanalysis of prolonged discussion can accord with Putnam’s thick ethical terms or not. The last section of the paper pitfalls Putnam’s stance to accepting Habermas’ ‘discourse ethics’ that centers around the context of entangling ‘rational thoughts’ to ‘communication’, but he introduces the idea of fallibilism in a rational query that also attacks the Habermasian metaphysical idea of the validity of ethical statements that goes towards the truth. My next attempt is to see whether Putnam’s objective dictum towards morality that resonates the collapse of fact/value dichotomy from a universalistic stand can successfully evade Rorty’s naive realism (structured by linguistic representation) and Habermas’ ‘sociologism about values’ (a kind of minimalist ethics depending on solidarity) respectively. This sort of claim insists on a universalizable pattern of culture-relative value. I consider that the idea of a fact/value dichotomy engages with the inextricable entanglement between the normative and descriptive content, besides the epistemic values having exclusively intertwined with the structure of factual discourse that intends towards collapsing the fact/value dichotomy, a subjective universalizability predilection.

In Reason, Truth and History and certain related writings, Hilary Putnam attacked the fact-value distinction. This paper criticizes his arguments and defends the distinction. Putnam claims that factual statements presuppose values, that “the empirical world depends upon our criteria of rational acceptability,” and that “we must have criteria of rational acceptability to even have an empirical world.” The present paper argues that these claims are mistaken.

Hilary Putnam spent much of his career criticizing the fact/value dichotomy, and this became apparent already during the phase when he defended internal realism. He later changed his epistemological and metaphysical view by endorsing natural realism, with the consequence of embracing alethic pluralism, the idea that truth works differently in various discourse domains. Despite these changes of mind in epistemology and in theory of truth, Putnam went on criticizing the fact/value dichotomy. However, alethic pluralism (...) entails drawing distinctions among discourse domains, especially between factual and nonfactual domains, and these distinctions are in tension with the rejection of the fact/value dichotomy, as this would in principle hinder factual domains as genuine. This issue raises, prima facie, some doubts about the effective compatibility of these views. (shrink)

In his recent work, "The Collapse of the Fact-Value Dichotomy," Hilary Putnam traces the history of the fact-value dichotomy from Hume to Stevenson and Logical Positivism. The aim of this historical reconstruction is to undermine the foundations of the dichotomy, showing that it is of a piece with the dichotomy - untenable, as we know now - of "analytic" and "synthetic" judgments. Putnam's own thesis is that facts and values are "entangled" in (...) a way that precludes any attempt to draw a sharp distinction between "value judgments" and "matters of fact." The idea of an "entanglement of facts and values" Putnam rightly attributes to John Dewey, who - we should add - made of it the main issue in his controversy with Logical Positivism. Nevertheless, a closer inspection of the problem whose history Putnam summarizes could bring into light important aspects of it that have been neglected. It is worth reading in this connection the intercourse between Dewey and Stevenson. Secondly, it is striking that Putnam's version of the history of the fact-value dichotomy hardly mentions the problem that caused this very dichotomy to arise in the first place: i. e., the problem of insoluble moral disagreements. By contrast, Dewey's attack on the dualism of fact and value can be read as an attempt to redescribe this kind of disagreements in a way that makes room for intelligent inquiry, and consequently for rational expectations of agreement. The "entanglement thesis" surely is a part of this re-description. But then it must have implications - particularly for the analysis of value-justification - which are overlooked, or by-passed, by Putnam. This leaves the question open whether Putnam and Dewey subscribe to different versions of pragmatism with regard to norms and values. (shrink)

This chapter outlines a new disentangling strategy for moral epistemology. It builds on the fundamental distinction between value-neutrality and value-independence as two separate aspects of methodological austerity introduced by Matthew Kramer. This type of conceptual analysis is then applied to two major challenges in moral epistemology: globalised scepticism and debate fragmentation. Both challenges arise from collapsing the fact/value dichotomy. They can be addressed by comprehensive disentangling that runs along both dimensions – value neutrality vs. (...) value non-neutrality and value independence vs. value dependence. The success of this strategy rests on two factors. The first is broadening the scope of disentangling to include theoretical-explanatory values on a par with distinctly ethical values. The second is differentiating between wider and narrower conceptualisations of what value neutrality requires with respect to contested matters. The objective is to pre-empt unjust theorising, a distinctive form of epistemic injustice that derives from the exclusive methodological focus on ethical evaluations at the expense of epistemic ones. When these methodological conditions are fulfilled, opponents should gain the confidence to treat each other as fellow inquirers engaged in the same project, that of reducing the scope of unhelpful disagreements.

In this reply to Professor Hookway’s lecture the comments are focused, first, on the topic of what dichotomies really are, since it is an illuminating way of understanding pragmatism in general and Putnam’s pragmatism in particular. Dichotomies are artifacts that we devise with some useful purpose in mind, but when inflated into absolute dichotomies they become metaphysical bogeys as it is illustrated by the twentieth century distinction between fact and value. Secondly, a brief comment on the so-called “thick” (...) ethical concepts and artifact terms is presented, and finally it is added a word on John L. Austin, whose approach to dichotomies is aligned with pragmatism and Putnam. (shrink)

In the diverse but related essays collected in Values and Evaluations, Julius Kovesi's central concerns are the nature of ideological thinking and the rational core of morality. «It is characteristic of ideological beliefs that their truth is upheld independent of the arguments for them,» he contends. He examines ideological tendencies in the Marxist tradition, in attempts to demythologize Christianity, and in modern British ethical theory. In ethics, he continues the attack on the fact/value dichotomy he began in (...) Moral Notions, a dichotomy he thinks has ideological sources. In theology, he argues that demythologizing is really a form of «remythologizing.» A long study of Moses Hess's essay On the Essence of Money is used to illuminate the early thought of Marx.

Within the Thomistic moral tradition, the is-ought gap is regularly treated as identical to the fact-value gap, and these two dichotomies are also regularly treated as being identical to Aristotle and Aquinas’s distinction between the practical and speculative intellect. The question whether (and if so, how) practical (‘ought’) knowledge derives from speculative (‘is’) knowledge has driven some of the fiercest disputes among the schools of Thomistic natural lawyers. I intend to show that both of these identifications are wrong (...) and the debate has been misframed. The is-ought gap is not the fact-value gap, nor does the is-ought gap correspond to Aquinas’s distinction between the speculative and practical. This opens the possibility of a resolution--within the Thomistic school--to a debate that has, heretofore, proven particularly resistant of consensus. I close by offering a tentative account of precisely how synderesis gives us our first awareness of moral law from a prior speculative understanding. (shrink)

Fact/value holism has become commonplace in philosophy of science, especially in feminist literature. However, that facts are bearers of empirical content, while values are not, remains a firmly-held distinction. I support a more thorough-going holism: both facts and values can function as empirical claims, related in a seamless, semantic web. I address a counterexample from Kourany where facts and values seem importantly discontinuous, namely, the simultaneous support by the Nazis of scientifically sound cancer research and morally unsound political (...) policies. I conclude that even by the criteria available at the time, Nazi cancer research was empirically weak, and the weaknesses in their research are continuous with their moral failures in just the ways predicted by the holism I support.

While the Value-Free Ideal of science has suffered compelling criticism, some advocates like Gregor Betz continue to argue that science policy advisors should avoid value judgments by hedging their hypotheses. This approach depends on a mistaken understanding of the relations between facts and values in regulatory science. My case study involves the morning-after pill Plan B and the “Drug Fact” that it “may” prevent implantation. I analyze the operative values, which I call zygote-centrism, responsible for this hedged (...) drug label. Then, I explain my twofold account of value-ladenness, involving the constitutive role of value judgments in science and the social function of facts as political tools. Because this drug fact is ineliminably value-laden in both senses, I conclude that hedged hypotheses are not necessarily value-free. (shrink)

Theories of slurs mostly fall into two camps. According to conjunctivists, uses of slurs conventionally perform two distinct speech acts. The first is a non-derogatory act of referring to a kind, and the second is a non-referential act of derogation. The first act is also performed by their neutral counterparts. Minimalists, by contrast, think that uses of slurs conventionally perform the non-derogatory act of referring associated with their neutral counterparts, and that it all. I argue against both these approaches, by (...) demonstrating that they fail to capture the full range of slurs’ occurrences. I focus on three important cases: (i) a bigot’s use of slurs, (ii) their (non-reclaimed) use by slurs’ targets, and (iii) the use of slurs in quotational contexts. I develop a novel and deflationary semantics for slurs that occupies a space between conjunctivism and minimalism, according to which uses of slurs conventionally perform a single act of derogatory reference. This view bucks the orthodoxy in maintaining that the meanings of slurs do not divide along fact/value lines. Interestingly, this is for reasons that don’t apply to 'thick' terms, like 'brave' and 'wanton'. (shrink)

This paper aims to show errors in common methodology of reasoning about macroeconomic theory. The error comes from confusion about descriptive and scientific methods of inquiry being used as a means of justifying conclusions with a normative basis. I will argue that many tools used in theorizing about the political economy that are thought of as able to express an isolated variable proving a normative point, actually contain normative assumptions which impact the soundness of the conclusion. The hidden values generally (...) serve to justify the status quo. Looking at my argument from a metaperspective, I argue that some popular methodology winds up in the general state of circular reasoning. I will try to weave two arguments together, the first is showing how economic concepts are value-laden, and also that they are implicit values of ideology, and operate as a powerful tool for the status quo. The ideology learns that things must be what they are, because the rest of the ideology seeks to justify it. There is both a factual and a value-driven thesis to this paper. Using examples I show how economic concepts that are thought of as being value neutral, are actually implicitly holding values that uphold the status quo and the growing tides of income inequality. I also wish to demonstrate how ideology constructs the common understanding, and how this effort keeps the populace from seeking emancipatory economic ideals and tax reform. (shrink)

What is the connection between dispositions and ethics? Some might think very little and those who are interested in dispositions tend to be metaphysicians whose interests are far from value. However, we argue in this paper that dispositions and dispositionality are central to ethics, indeed a precondition. Ethics rests on a number of notions that are either dispositional in nature or involve real dispositions or powers at work. We argue for a dispositional account of value that offers an (...) alternative to the traditional fact-value dichotomy. We explain the place of value within a structure that explains the possibility of ethics. Elsewhere in this structure, we argue that moral responsibility is a precondition for ethics and that it is a dispositional notion depending critically on what Mumford and Anjum have called the dispositional modality. Moral responsibility in turn depends on there being both agency and normativity. We argue that intentionality and agency are preconditions for agency and that value is a precondition of normativity. All these notions are dispositional and make best sense if there are real dispositions or causal powers of agents. (shrink)

Inspired by the text entitled The Collapse of the Fact/Value Dichotomy and Other Essays (2004) of Hilary Putnam, the volume focuses on the theory and practice of knowledge, but one can legitimately extend it to other fields, most especially in aesthetics. Certain observable features in the fields of aesthetics, practice and artistic creation show that old evaluation criteria may now be obsolete. This is because upon further consideration, the definition of value remains opaque : should the (...) artwork be judged according to its moral value, its market value, or its formal value ? To side with or against the concept of value in art and aesthetics does not preclude a certain number of differences concerning the very nature of what is meant by value. If traditionally the ‘fact’ was the work, taken in all its tangibility, currently the materiality of the object no longer seems to play such a major role. Art is increasingly populated by so-called ‘immaterial’ or ‘ephemeral’ works and is therefore rarely, or badly, quantifiable according to old aesthetic and economic evaluation criteria. The progressively pragmatic contextualization of works within the social space puts forward a new definition of aesthetic value, no longer eternal and ideal, but rather anchored in the sensible and the politico-economic issues of a culturally specific situation. The current changes too support the idea that the question of ‘value’ and its confrontation with the concept of ‘fact’ is urgent. What role do artistic practices and aesthetic theories play ? A role of emancipation, of liberation, escape, or transformation ? Or on the contrary, could art become another means to subject individuals to the status quo ? As can easily be noticed, the question of maintaining or rejecting the dichotomy of facts and values is at the heart of the most pressing issues. (shrink)

Some prominent scientists and philosophers have stated openly that moral and political considerations should influence whether we accept or promulgate scientific theories. This widespread view has significantly influenced the development, and public perception, of intelligence research. Theories related to group differences in intelligence are often rejected a priori on explicitly moral grounds. Thus the idea, frequently expressed by commentators on science, that science is “self-correcting”—that hypotheses are simply abandoned when they are undermined by empirical evidence—may not be correct in all (...) contexts. In this paper, documentation spanning from the early 1970s to the present is collected, which reveals the influence of scientists’ moral and political commitments on the study of intelligence. It is suggested that misrepresenting findings in science to achieve desirable social goals will ultimately harm both science and society. (shrink)

It is no secret that disputes between philosophers working in separate traditions do arise, especially along the analytic-continental fault line. Flashes of disagreement between analytic philosophers and pragmatists have also been witnessed in recent years. Many analytic philosophers allege that pragmatism lacks logical rigor or contains a naïve theory of truth (i.e., what is useful is true). Some pragmatists contend that analytic philosophy fails to address practical issues—what John Dewey called ‘the problems of men’—and endorses a faulty fact-value (...) dichotomy. Many of these disagreements reflect mistaken views on both sides of the analytic-pragmatist divide, views that could easily be corrected through more open dialogue across the two traditions. Since at least the mid-twentieth century, analytic philosophers and pragmatists have reached out to each other in an effort to bridge the divide. When the founders of the analytic tradition, the logical positivists, immigrated from Austria and Germany to the United States during World War II, the stage was set for greater collaboration. Indeed, the logical positivist Otto Neurath invited the American pragmatist John Dewey to contribute to the Encyclopedia of Unified Sciences. This collaborative spirit finds expression in the present collection of essays. According to the editor, ‘(t)his volume aims to clarify the most recent developments in this process (of collaboration), focusing on the key theoretical issues in the revival of salient themes in the classic tradition of American philosophy within the context of analytical thought’ (xi).

Ever since Darwin people have worried about the sceptical implications of evolution. If our minds are products of evolution like those of other animals, why suppose that the beliefs they produce are true, rather than merely useful? We consider this problem for beliefs in three different domains: religion, morality, and commonsense and scientific claims about matters of empirical fact. We identify replies to evolutionary scepticism that work in some domains but not in others. One reply is that evolution can (...) be expected to design systems that produce true beliefs in some domain. This reply works for commonsense beliefs and can be extended to scientific beliefs. But it does not work for moral or religious beliefs. An alternative reply which has been used defend moral beliefs is that their truth does not consist in their tracking some external state of affairs. Whether or not it is successful in the case of moral beliefs, this reply is less plausible for religious beliefs. So religious beliefs emerge as particularly vulnerable to evolutionary debunking.

This paper argues for confirmational holism about facts and values. This position is similar to one defended by (among others) Hilary Putnam, but the argument is importantly different. Whereas Putnam et al. rely on examples of the putative entanglement of facts and values – a strategy which I suggest is vulnerable to parrying – my argument proceeds at a more general level. I argue that the explanation of action can not be separated from our practical reasoning, and for this reason, (...) the ‘webs’ of value and fact judgments are joined in the same way that Quine holds the judgments of mathematics and natural science to be.

How much can we shape the emotions we experience? Or to put it another way, how plastic are our emotions? It is clear that the exercise of identifying the degree of plasticity of emotion is futile without a prior specification of what can be plastic, so we first propose an analysis of the components of emotions. We will then turn to empirical data that might be used to assess the degree of plasticity of emotions.

This essay is about the Wolfgang Köhler’s philosophical ideas expressed in his The Place of Value in a World of Facts of 1938. Köhler, who strongly supports a scientific world view, considers the question as to whether science is able to cope with human values, besides natural facts. Relying upon phenomenological analyses, and on his previous researches in natural philosophy, Köhler introduces his doctrine of “epistemological dualism”. From a historical point of view, this theory exhibits some similarity with the (...) philosophical ideas expressed by Köhler’s Berlin mentor Carl Stumpf. It is argued that Köhler’s epistemological dualism actually supports ontological monism and aims at offering a unified view of natural facts and human values. (shrink)

"The Personal is Political": This was an often-heard slogan of feminist groups in the late sixties and early seventies. The slogan is no doubt open to many interpretations. There is one interpretation which touches on the epistemology of social facts, viz. the slogan claims that in assessing the features of a political system, personal experiences have privileged evidentiary value. For instancte, in the face of third person reports about political corruption, I may remain unmoved in my belief that the (...) political powers are morally upstanding, and it is only when I myself am adversely affected, that I come to change my views. There are two standard patterns of explanation of this type of belief formation: (i) We know that third-person reports may be lessreliable than first-person experiences; (ii) If the third-person reports are no less reliable than first-person experiences, we may just be dealing with a standard pattern of epistemic irrationality. However, we argue that there is also a much more surprising pattern of explanation: under certain conditions, a Bayesian argument can be proffered to the effect that it is rational to change one's beliefs in the face of personal experiences and not in the face of third-person reports, even if these experiences and reports are equally reliable. Hence, the feminist slogan (at least on one particular interpretation of it) receives unexpected support from Bayesian comers. We also show that this pattern of explanation has surprising repercussions on the question of the evidentiary value of miracles in philosophy of religion. (shrink)

In this paper we use a series of examples to show how oppositions and dichotomies are fundamental in legal argumentation, and vitally important to be aware of, because of their twofold nature. On the one hand, they are argument structures underlying various kinds of rational argumentation commonly used in law as a means of getting to the truth in a conflict of opinion under critical discussion by two opposing sides before a tryer of fact. On the other hand, they (...) are argument structures underling moves made in strategic advocacy by both sides that function as platforms for different kinds of questionable argumentation tactics and moves that are in some instances tricky and deceptive.

Pacifists and their opponents disagree not only about moral questions, but most often about factual questions as well. According to my reconstruction of pacifism, this is not surprising, since the pacifist, legitimately, looks at the facts in the light of her system of values. Her opponent, in turn, looks at the facts in the light of an alternative value system. And the quarrel between the two parties about supposedly descriptive matters never ceases, as there is no objective reality that (...) could settle the issue. The pacifist’s value-laden perspective on reality is informed by Christian charity and humility: a specific mixture of optimism and pessimism. (shrink)

I examine and resolve an exegetical dichotomy between two main interpretations of Peirce’s theory of abduction, namely, the Generative Interpretation and the Pursuitworthiness Interpretation. According to the former, abduction is the instinctive process of generating explanatory hypotheses through a mental faculty called insight. According to the latter, abduction is a rule-governed procedure for determining the relative pursuitworthiness of available hypotheses and adopting the worthiest one for further investigation—such as empirical tests—based on economic considerations. It is shown that the Generative (...) Interpretation is inconsistent with a fundamental fact of logic for Peirce—i.e., abduction is a kind of inference—and the Pursuitworthiness Interpretation is flawed and inconsistent with Peirce’s naturalistic explanation for the possibility of science and his view about the limitations of classical scientific method. Changing the exegetical locus classicus from the logical form of abduction to insight and economy of research, I argue for the Unified Interpretation according to which abduction includes both instinctive hypotheses-generation and rule-governed hypotheses-ranking. I show that the Unified Interpretation is immune to the objections raised successfully against the Generative and the Pursuitworthiness interpretations. (shrink)

Abstract In a context of human demographic, technological and economic pressure on natural systems, we face some demanding challenges. We must decide 1) whether to “preserve” nature for its own sake or to “conserve” nature because nature is essentially a reservoir of goods that are functional to humanity’s wellbeing; 2) to choose ways of life that respect the biodiversity and evolutionary potential of the planet; and, to allow all this to come to fruition, 3) to clearly define the role of (...) scientific expertise in a democratic society, recognizing the importance of biospheric equilibrium. In fact, in socio-scientific controversies, which are characterized by complex linkages between some life and environmental sciences objects and economic, political and ethical issues, a posture of transparent, impartial commitment is appearing, more and more, as a deontological necessity.

The present contribution might be regarded as a kind of defense of the common sense in logic. It is demonstrated that if the classical negation is interpreted as the minimal negation with n = 2 truth values, then deviant logics can be conceived as extension of the classical bivalent frame. Such classical apprehension of negation is possible in non- classical logics as well, if truth value is internalized and bivalence is replaced by bipartition.

Philosophers have used the terms 'impersonal' and 'personal value' to refer to, among others things, whether something's value is universal or particular to an individual. In this paper, I propose an account of impersonal value that, I argue, better captures the intuitive distinction than potential alternatives, while providing conceptual resources for moving beyond the traditional stark dichotomy. I illustrate the practical importance of my theoretical account with reference to debate over the evaluative scope of cultural heritage.

In this paper I shall defend the idea that there is an abstract and general core meaning of objectivity, and what is seen as a variety of concepts or conceptions of objectivity are in fact criteria of, or means to achieve, objectivity. I shall then discuss the ideal of value-free science and its relation to the objectivity of science; its status can be at best a criterion of, or means for, objectivity. Given this analysis, we can then turn (...) to the problem of inductive risk. Do the value judgements regarding inductive risk really pose a threat to the objectivity of science? I claim that this is not the case because they do not lower the thresholds scientifically postulated for objectivity. I shall conclude the paper with a discussion of under-appreciated influences of values on science, which indeed pose a serious threat to the objectivity of some scientific disciplines. (shrink)

It is often assumed that there is a necessary relationship between historical value and irreplaceability, and that this is an essential feature of historical value’s distinctive character. Contrary to this assumption, I argue that it is a merely contingent fact that some historically valuable things are irreplaceable, and that irreplaceability is not a distinctive feature of historical value at all. Rather, historically significant objects, from heirlooms to artifacts, offer us an otherwise impossible connection with the past, (...) a value that persists even in the face of suitable replacements.

Boolean-valued models of set theory were independently introduced by Scott, Solovay and Vopěnka in 1965, offering a natural and rich alternative for describing forcing. The original method was adapted by Takeuti, Titani, Kozawa and Ozawa to lattice-valued models of set theory. After this, Löwe and Tarafder proposed a class of algebras based on a certain kind of implication which satisfy several axioms of ZF. From this class, they found a specific 3-valued model called PS3 which satisfies all the axioms of (...) ZF, and can be expanded with a paraconsistent negation *, thus obtaining a paraconsistent model of ZF. The logic (PS3 ,*) coincides (up to language) with da Costa and D'Ottaviano logic J3, a 3-valued paraconsistent logic that have been proposed independently in the literature by several authors and with different motivations such as CluNs, LFI1 and MPT. We propose in this paper a family of algebraic models of ZFC based on LPT0, another linguistic variant of J3 introduced by us in 2016. The semantics of LPT0, as well as of its first-order version QLPT0, is given by twist structures defined over Boolean agebras. From this, it is possible to adapt the standard Boolean-valued models of (classical) ZFC to twist-valued models of an expansion of ZFC by adding a paraconsistent negation. We argue that the implication operator of LPT0 is more suitable for a paraconsistent set theory than the implication of PS3, since it allows for genuinely inconsistent sets w such that [(w = w)] = 1/2 . This implication is not a 'reasonable implication' as defined by Löwe and Tarafder. This suggests that 'reasonable implication algebras' are just one way to define a paraconsistent set theory. Our twist-valued models are adapted to provide a class of twist-valued models for (PS3,*), thus generalizing Löwe and Tarafder result. It is shown that they are in fact models of ZFC (not only of ZF). (shrink)

How ought you to evaluate your options if you're uncertain about what's fundamentally valuable? A prominent response is Expected Value Maximisation (EVM)—the view that under axiological uncertainty, an option is better than another if and only if it has the greater expected value across axiologies. But the expected value of an option depends on quantitative probability and value facts, and in particular on value comparisons across axiologies. We need to explain what it is for such (...) facts to hold. Also, EVM is by no means self-evident. We need an argument to defend that it’s true. This book introduces an axiomatic approach to answer these worries. It provides an explication of what EVM means by use of representation theorems: intertheoretic comparisons can be understood in terms of facts about which options are better than which, and mutatis mutandis for intratheoretic comparisons and axiological probabilities. And it provides a systematic argument to the effect that EVM is true: the theory can be vindicated through simple axioms. The result is a formally cogent and philosophically compelling extension of standard decision theory, and original take on the problem of axiological or normative uncertainty. (shrink)

2nd edition. Many-valued logics are those logics that have more than the two classical truth values, to wit, true and false; in fact, they can have from three to infinitely many truth values. This property, together with truth-functionality, provides a powerful formalism to reason in settings where classical logic—as well as other non-classical logics—is of no avail. Indeed, originally motivated by philosophical concerns, these logics soon proved relevant for a plethora of applications ranging from switching theory to cognitive modeling, (...) and they are today in more demand than ever, due to the realization that inconsistency and vagueness in knowledge bases and information processes are not only inevitable and acceptable, but also perhaps welcome. The main modern applications of (any) logic are to be found in the digital computer, and we thus require the practical knowledge how to computerize—which also means automate—decisions (i.e. reasoning) in many-valued logics. This, in turn, necessitates a mathematical foundation for these logics. This book provides both these mathematical foundation and practical knowledge in a rigorous, yet accessible, text, while at the same time situating these logics in the context of the satisfiability problem (SAT) and automated deduction. The main text is complemented with a large selection of exercises, a plus for the reader wishing to not only learn about, but also do something with, many-valued logics. (shrink)

In the growing literature on decision-making under moral uncertainty, a number of skeptics have argued that there is an insuperable barrier to rational "hedging" for the risk of moral error, namely the apparent incomparability of moral reasons given by rival theories like Kantianism and utilitarianism. Various general theories of intertheoretic value comparison have been proposed to meet this objection, but each suffers from apparently fatal flaws. In this paper, I propose a more modest approach that aims to identify classes (...) of moral theories that share common principles strong enough to establish bases for intertheoretic comparison. I show that, contra the claims of skeptics, there are often rationally perspicuous grounds for precise, quantitative value comparisons within such classes. In light of this fact, I argue, the existence of some apparent incomparabilities between widely divergent moral theories cannot serve as a general argument against hedging for one's moral uncertainties.

Epistemic peer disagreement raises interesting questions, both in epistemology and in philosophy of science. When is it reasonable to defer to the opinion of others, and when should we hold fast to our original beliefs? What can we learn from the fact that an epistemic peer disagrees with us? A question that has received relatively little attention in these debates is the value of epistemic peer disagreement—can it help us to further epistemic goals, and, if so, how? We (...) investigate this through a recent case in paleoanthropology: the debate on the taxonomic status of Homo floresiensis remains unresolved, with some authors arguing the fossils represent a novel hominin species, and others claiming that they are Homo sapiens with congenital growth disorders. Our examination of this case in the recent history of science provides insights into the value of peer disagreement, indicating that it is especially valuable if one does not straightaway defer to a peer’s conclusions, but nevertheless remains open to a peer’s evidence and arguments.

This chapter centers around law's capacity to constitute practical reasons. In discussing this theme, consideration is given to law's artifactual character. The discussion falls into two main parts. In Section 1, I critically examine a skeptical line of thought about law's capacity to constitute reasons for action, which draws, in part, on law's artifactuality. I argue for a somewhat less skeptical (but still qualified) stance, according to which the fact that a legal directive has been issued can (notwithstanding the (...) artifactuality involved) be a reason for action, yet one that is underpinned by bedrock values which (under certain conditions and constraints) law is apt to serve. In Section 2, I consider whether, and in what sense, law can acquire an even more 'robust' status as a source of practical reasons. I focus particularly on Joseph Raz's position about the normative force of (legitimate) legal authority and on an alternative position I have proposed and advocated elsewhere. (shrink)

This chapter considers whether legal requirements can constitute reasons for action independently of the merits of the requirement at hand. While jurisprudential opinion on this question is far from uniform, sceptical views are becoming increasingly dominant. Such views typically contend that, while the law can be indicative of pre-existing reasons, or can trigger pre-existing reasons into operation, it cannot constitute new reasons. This chapter offers support to a somewhat less sceptical position, according to which the fact that a legal (...) requirement has been issued can be a reason for action, yet one that is underpinned by bedrock values which law is apt to serve. Notions discussed here include a value-based conception of reasons as facts ; a distinction between complete and incomplete reasons ; and David Enoch’s idea of triggering reason-giving. Following a discussion of criticism against the view adopted here, the chapter concludes by considering some more ‘robust’ conceptions of law’s reason-giving capacity. (shrink)

ABSTRACT: We argue that the so-called ‘Primary’ and ‘Secondary’ Value Problems for knowledge are more easily solved than is widely appreciated. Pritchard, for instance, has suggested that only virtue-theoretic accounts have any hopes of adequately addressing these problems. By contrast, we argue that accounts of knowledge that are sensitive to the Gettier problem are able to overcome these challenges. To first approximation, the Primary Value Problem is a problem of understanding how the property of being knowledge confers more (...) epistemic value on a belief than the property of being true. The Secondary Value is a problem of understanding how, for instance, property of being knowledge confers more epistemic value on a belief than the property of being jointly true and justified. We argue that attending to the fact that beliefs are ongoing states reveals that there is no difficulty in appreciating how knowledge might ordinarily have more epistemic value than mere true belief or mere justified true belief. We also explore in what ways ordinary cases of knowledge might be of distinctive epistemic value. In the end, our proposal resembles the original Platonic suggestion in the Meno that knowledge is valuable because knowledge is somehow tied to the good of truth. (shrink)

Although at first glance, “facts” are the paradigms of straightforwardness, something about facts seems to invite perpetual controversy and dichotomizing. Innumerable bifurcations on the topic have included "Facts vs. Theories”, “Facts vs. Appearance”, "Facts vs. Values", ... and, popular nowadays, "(Real)Facts vs. Fake Facts". This paper most aligns with the facts vs. theories model, so far as whatever facts are, theories seem to be constructed stories that are necessary for connecting and interpreting the facts. Yet the boundary between the two (...) is fluid and fuzzy: Fact in one context is theory in another, depending on what is being accepted or contested at the time. This paper’s views are compatible with—but neutral on the plausibility of having—an optimism like Peirce’s that scientific inquiry may nonetheless converge towards a consensus. To illustrate the challenges of finding “straightforward” facts, the paper includes a case example, related to research on possible health effects of exposure to electromagnetic-field radiation (EMF). _ The source paper for this 2018 update was originally presented at the University of Waterloo 30th Anniversary Philosophy Conference, 1993.

The concept of ecosystem services is a way of visualizing the instrumental value that nature has for human beings. Most ecosystem services can be performed by more than one species. This fact is sometimes used as an argument against the preservation of species. However, even though substitutability does detract from the instrumental value of a species, it also adds option value to it. The option value cannot make a substitutable species as instrumentally valuable as a (...) non-substitutable species, but in many cases, it can add enough value to make the species more valuable than the projects that threaten its existence.

Existence value refers to the value humans ascribe to the existence of something, regard­less of whether it is or will be of any particular use to them. This existence value based on preference satisfaction should be taken into account in evaluating activities that come with a risk of species extinction. There are two main objections. The first is that on the preference satisfaction interpretation, the concept lacks moral importance because satisfying people’s preferences may involve no good or (...) well-being for them. However, existence value can be based on a restricted version of the preference satisfaction theory, which is not vulnerable to the skeptical arguments about the link between preference satisfaction and well-being. The second objection is that even if preference satisfaction can be linked to well-being, understanding existence value in terms of individual preference satisfaction is incoherent, because existence value reflects disinterested preferences that involve no benefits to the individual. However, the fact that existence value may involve disinterested preferences does not threaten the coherence of the concept, but suggests that it does not fit smoothly into the “utilitarian” or “welfarist” framework it is commonly considered within. A pluralistic normative approach based on prima facie duties can be an alternative to standard utilitarian-style approaches for considering existence value in concrete cases involving a risk of species extinction, such as through deep sea mining.

In epistemology, the concept of knowledge is of distinctive interest. This fact is also reflected in the discussion of epistemic value, which focuses to a large extend on the value problem of knowledge. This discussion suggests that knowledge has an outstanding value among epistemic standings because its value exceeds the value of its constitutive parts. I will argue that the value of knowledge is not outstanding by presenting epistemic standings of checking, transferring knowledge, (...) and proving in court, whose values exceed the value of knowledge in certain contexts. Moreover, the values of these other epistemic standings do not always rely on the value of knowledge. In terms of value, knowledge is not an outstanding epistemic concept. Hence, in terms of value we cannot find support for the privileged position that knowledge enjoys in epistemology. (shrink)

Many philosophers recognize that, as a matter of psychological fact, one can believe something valuable without valuing it. I argue that it is also possible to value something without believing it valuable. Agents can genuinely value things that they neither believe disvaluable nor believe valuable along a scale of impersonal value.

Abstract Criteria of scientific value are of different kinds. This paper concerns ultimate criteria, i.e. the axiology of science. Most ultimate criteria are multi?dimensional. This gives rise to an aggregation problem, which cannot be adequately solved with reference to attitudes and behaviour within the scientific community. Therefore, in many cases, there is no fact of the matter as to whether one theory is better than another. This, in turn, creates problems for methodology.

To what extent do we value future generations? It may seem from our behavior that we don’t value future generations much at all, at least in relation to how much we value present generations. However, in his book _Death and the Afterlife_, Samuel Scheffler argues that we value the future even _more_ than we value the present, even though this is not immediately apparent to us. If Scheffler’s argument is sound, then it has important ramifications: (...) It would give us a strong motivation to put more energy into abating environmental crises like climate change, and it supports at least a limited form of ethical _longtermism_. However, in this paper, I show that Scheffler’s argument is fallacious. Scheffler claims that we do not regard the fact that we in the present generation will all die relatively soon as a catastrophe, but we do regard the non-existence of future generations as a catastrophe. But the particular scenario used by Scheffler to illustrate this point—the plot of the book _The Children of Men_—is one in which _both_ the present generation will perish _and_ there will be no future generations, and it is this _conjunction_ that is catastrophic, thus giving no information about which is worse. I suggest other ways to compare our valuations of present and future generations, and recommend that philosophers who are interested in the moral psychology of how we value future generations ought to engage with social science, as it is an empirical issue.

Philosophical reflection on ethical value may be motivated in a number of ways. One common origin can occur when we observe that we often do not agree with people around us in their ethical commitments, and begin to puzzle how to make sense of that fact. Most of us have some strong beliefs as to ways our world can be a morally better or worse place: we agree for instance that the world is a better place for having (...) less slavery in it than it used to. That is to say, we think slavery is a bad — a morally bad — thing. Similarly, most of us agree that the world is better off for our being in time to grab a small child out of the path of a speeding automobile than it would be if we came a moment too late. Saving a child from death or grave harm is a good — morally good — thing. The idea that the world includes ethical values like the goodness and badness of such things seems unproblematic when we focus on issue on which most of us agree. Yet our confidence that the world contains such values wobbles when we turn our attention to more controversial issues. (shrink)

This paper reviews arguments concerning the relation between relativism and tolerance, both whether tolerance entails relativism, and whether relativism entails tolerance. Two new arguments are offered to support the contention that there is no necessary relation between relativism and tolerance. In particular, building on the classic argument by Geoffrey Harrison, this paper argues that even if there is no strict dichotomy between facts and values, as Harrison had assumed, relativism still does not entail tolerance for every relativized perspective.

Conditioning can produce desires that seem to be outside of--or “alien” to--the agent. Desire-based theories of welfare claim that the satisfaction of desires creates prudential value. But the satisfaction of alien desires does not seem to create prudential value. To explain this fact, we need an account of alien desires that explains their moral status. In this paper I suggest that alien desires are desires that would be rational if the person believed something that in fact (...) she believes is false. Such desires could be produced by mental representations--or “quasi-beliefs”--with contents that conflict with the contents of one’s beliefs. The postulation of quasi-beliefs is plausible, for they explain important empirical facts about our behavior--facts that are difficult if not impossible to explain otherwise. Alien desires, I argue, involve quasi-beliefs with contents that conflict with the contents of regular beliefs. This theory provides the distinction between alien and authentic desires that desire-based theories of welfare need. (shrink)
