The conciliationist and steadfast approaches have dominated the conversation in the epistemology of disagreement. In this paper, drawing on Jennifer Lackey’s justificationist approach and the casuistry paradigm in medical ethics, I will develop a more contextual epistemology of political disagreement. On this account, a given political disagreement’s scope, domain, genealogy, and consequence can be helpful for determining whether we should respond to that disagreement at the level of our confidence, beliefs, or with policy. Though some may argue that responding with (...) policy is a practical consideration instead of an epistemic matter, I argue that even policy responses to disagreements have an epistemic dimension to them that we should not ignore.

According to the scientific "justificationist" method, knowledge consisted of proven sentences. Classical intellectuals (or "rationalists," in the narrow sense of the term) have accepted extremely varied - and powerful "proofs", through revelation, intellectual intuition, experience. These, with the help of logic, have allowed them to prove any kind of scientific statement. Classical empiricists accepted as axioms only a relatively small set of "factual propositions" that expressed "hard facts". The value of their truth has been established by experience and has been (...) the empirical basis of science. DOI: 10.13140/RG.2.2.28722.25288. (shrink)

Justificationism is the epistemology that enjoins us to choose our beliefs according to this principle: choose all and only those beliefs and at an appropriate degree of confidence that one can justify, either by an intellectual certificate or empirical warrant. My article argues that most forms of justificationism require the truth of doxastic voluntarism, the doctrine that one may choose ones specific beliefs. However, since belief is involuntary, justificationism is severely undermined. Justificationism as stated couldn’t be (...) practised; since believing is not something we can do at will as a basic action. Although devastating to any subjectivist justificationism, it does not undermine our ability to cultivate, through long-term choices, the most rational attitude in the search for truth and the growth of knowledge. A major rival of subjective justiticationism (SJ) is critical rationalism (CR). CR is the doctrine that progress in the growth of knowledge occurs through the unrelenting criticism of competing unjustified conjectural attempts to solve problems. The objective methods and standards involved in CR are unaffected because following (or not) an objective method is something we can do at will. (shrink)

Any adequate philosophy of technology needs to take a clear stance with regard to the limits of criticizability. While observing the canons of criticizability may appear to be simple, many philosophical approaches (whether towards technology or other topics) abandon comprehensive criticizability by adopting some forms of justificationist or essentialist epistemology. This paper aims to show that criticizability can only be upheld by subscribing to a non-justificationist epistemology and by acknowledging the propositions/standards dichotomy; failing to do so leads to undesirable epistemic (...) consequences.

I thank Professor Otteson for his review of Escape from Leviathan (EfL). His exposition of what I wrote is relatively accurate. I shall here do my best to correct any misunderstandings and reply to his welcome criticisms, ignoring our various points of agreement and his generous praise.

A large part of Richard Rorty’s works focus on criticizing the received view about philosophy. He argues, in his historical reconstruction of philosophical activity, that there has always been a misconception about philosophy in the history of philosophy. This misconception assumes that philosophy aims to grasp the ultimate knowledge, so it desperately engages in an attempt to achieve “truth”. In this view, which he calls representationalism and points to it by the metaphor of the mirror of nature, knowledge aims to (...) represent something out of mind, and the duty of philosophy is to put forward a theory about the representation. According to Rorty, based on this popular view philosophy is a foundational discipline that aims to evaluate epistemological claims of other disciplines. Rorty attempts to criticize and reject this Cartesian epistemological agenda for philosophy. Rorty’s approach to philosophy is therapeutic; that is, he tries to resolve philosophical problems rather than solve them. By adopting a historical method, Rorty seeks to show that “philosophy as epistemology” is a result of the dominance of what he calls the metaphor of the mirror of nature. From a critical rationalist perspective, the present article intends to critique Rorty’s views on epistemology. In this paper, Rorty’s historiographical approach is criticized in several ways. First, Rorty offers a one-sided and biased reconstruction of the history of philosophy to fit the abovementioned metaphor. Secondly, he treats history as rigid data from which it is possible to draw doctrinal conclusions. Whereas, as critical rationalists have said time and again, history by itself has no meaning. Moreover, Rorty’s justificationism is criticized. Rorty maintains that knowledge needs to be justified, and since it cannot be justified through representation, it must be justified by the consent of society. In other words, agreement in a group of people can provide an epistemic authority. Thus, both Rorty’s view and foundationalism, despite their differences, share justificationism in epistemology. That is, they both believe that knowledge needs to be justified. On the other hand, as critical rationalists have shown, justification in any shape and form, whether internal or external, is neither possible nor necessary. We also attempt to illustrate how Rorty’s epistemological approach results in confusion between epistemology and psychology; moreover, his epistemological behaviorism still suffers from some sort of justifications. In conclusion, Rorty expresses his criticism of epistemology with the metaphor of the mirror of nature. According to him, foundationalism is the result of the conflation of the Platonic conception of knowledge as something unchangeable, with the Cartesian mind that seeks certainty. However, his ignorance of the main crux of the matter in epistemology causes his own suggestion of epistemological behaviorism to suffer from the same problem, that is justificationism, which now appears in another form, i.e., social consensus. While, as critical rationalists repeated time and again, justification is neither possible nor necessary and not even desirable. They have shown that a non-justificationist approach to knowledge aimed at truth as a regulative idea could be a better approach. (shrink)

Does having an initially high level of justified confidence in a belief vindicate remaining steadfast in the face of disagreement? According to one prominent view in the literature, namely Jennifer Lackey's justificationist position, the answer is yes so long as one also has personal information that provides a symmetry-breaker. In this article, I raise a problem for the justificationist view. On the most straightforward reading of the justificationist position, personal information always provides a symmetry-breaker in a peer dispute over a (...) belief in which one has high justified confidence. However, this position is implausibly strong because it renders epistemically permissible a dogmatic attitude in a relevant set of peer disagreements. Alternatively, weaker readings of the view fail to provide a perspicuous account of when high justified confidence matters in a disagreement. (shrink)

Dummett has recently presented his most mature and sophisticated version of justificationism, i.e. the view that meaning and truth are to be analysed in terms of justifiability. In this paper, I argue that this conception does not resolve a difficulty that also affected Dummett’s earlier version of justificationism: the problem that large tracts of the past continuously vanish as their traces in the present dissipate. Since Dummett’s justificationism is essentially based on the assumption that the speaker has (...) limited (i.e. non-idealized) cognitive powers, no further refinement of this position is likely to settle the problem of the vanishing past.

Based on an epistemological approach, humanities and natural sciences are two completely different realms that are governed by different rules. From this position, it is usually concluded that these two should not interfere in each other's territory. This idea, which also has supporters in other categorizations such as science and theology, relies mainly on Wittgenstein's doctrines. The purpose of the article is to argue that such an approach ultimately leads to the isolation of different realms of knowledge. We argue why (...) this position is incorrect and has adverse consequences for the development of knowledge in all domains. (shrink)

This essay examines sections relevant to libertarianism in Will Kymlicka’s Contemporary Political Philosophy: An Introduction (2nd ed.), making and explaining the following criticisms. Kymlicka’s “preface” misconstrues political philosophy’s progress, purpose, and its relation to libertarianism. In his “introduction”, his “project” mistakes libertarianism as “right-wing”, justice as compromise among “existing theories”, and equality as the “ultimate value.” His “a note on method” in effect takes as axioms, beyond philosophical examination, various alleged desiderata and the necessary moral role of the state. Moreover, (...) his “ultimate test” being “our considered convictions” amounts to a conservative and illogical justificationism at odds with radical and coherent critical rationalism. Kymlicka’s chapter on “libertarianism” mistakes it as, inherently and unavoidably, free-marketist, anti-consequentialist, deontological, Nozickian, requiring “a foundational moral premiss, without objective content, unmaximisable, indistinguishable from license, equality-based, anti-anarchist, “self-defeating”, indefensibly “unfair”, impractically “philosophical”, and without influence. A different version of libertarianism easily withstands all Kymlicka’s antipathetic criticisms. (shrink)

Veritists hold that the goal of inquiry is true belief, while justificationists contend that the goal of inquiry is justified belief. Recently, Christoph Kelp makes two new objections to both veritism and justificationism. Further, he claims that the two objections suggest that the goal of inquiry is knowledge. This paper defends a sophisticated version of veritism against Kelp's two objections.

This replies to Block 2019 (B19), which responds to Lester 2014 (L14). The main issues in the, varyingly sized, sections are as follows. 1 Further explanations of critical rationalism, the theory of liberty, and problems with the non-aggression principle. 2.1 The relationships among law, morality, and libertarianism. 2.2 The objective invasiveness of low-level radiation and that it is therefore an initiated imposition (albeit trivial) if someone inflicts it on non-consenting people. 2.3 The objective and subjective aspects of initiated impositions; and (...) how clashes can be resolved. 2.4 How liberty relates to risk and self-ownership. 2.5 Libertarian initial acquisition versus absolute property rights by labour-mixing. 2.6 Organisational note. 2.7 Libertarianism and mens rea. 2.8 Libertarian rectification versus lex-talionis doubling. 2.9 Indirectly clashing rights, self-preservation, trespasser-hiker, flagpole-grasper, and landmine-layer. 2.10 A logical point is not a moral point. 2.11 Pacifism and libertarianism. 3.1 A weak criticism of utilitarianism. 3.2 Hedonometers; approximate interpersonal comparisons of utility imply libertarianism; what a libertarian is; libertarian rankings. 4. Libertarian philosophy versus propertarian dogma. Coda: the need to take seriously the philosophical problems with propertarian-justificationist libertarianism. (shrink)

Richard Dawkins tries to establish an analogy between computer viruses and theistic belief systems, analyzing the latter in terms of his concept of the meme. The underlying thrust of Dawkins' argument is to downplay the role of truth and logic in the survival of theories and to emphasize humankind's helpless liability to incurable infection by doctrines that Dawkins regards as absurd. Dawkins supplies a list of "symptoms” of mind-infection. However, on closer investigation these characteristics are found to be either rather (...) weak protection against criticism or quite virtuous. Dawkins relies on a crude justificationism that could just as well be called a mind-virus. Applying Dawkins’ own selection of the general characteristics of a good meme protector and propagator leads to the conclusion that his particular theistic examples would actually impair copyability. -/- Scientific theories are better examples of memes with high longevity, fecundity, and fidelity. A Darwinian analysis of wishful and fearful thinking as useful to hypotheses-testing and goal-seeking organisms undermines Dawkins' attribution of absolute irrational stubbornness to theists. To counterbalance Dawkins' emphasis on the propagation of the absurd, I rehabilitate the Socratic emphasis on the importance of truth and logic in rhetoric, interpreted broadly as the theory of the successful propagation of a message. I use Popper's notion of situational analysis, and an evolutionary perspective to argue that rational standards of a message enhance its copyability. I further apply Popper’s notions of World 3, 2, and 1 to memes; this helps us see the perpetuation of a doctrine as a logical task. (shrink)

Primarily using philosophy, but also some social science, Escape from Leviathan (EfL) explains and defends what it calls an extreme version of the implicit ‘classical liberal compatibility thesis’: liberty, welfare, and anarchy are overwhelmingly complementary in normal practice (rationality is added for its intimate theoretical connections to these categories). This is done using theories, not definitions, of each concept. This important thesis is entirely positive. Therefore, somewhat unusually, all normative issues are avoided as irrelevant distractions in this context. In addition, (...) the epistemology used is also unorthodox. A justificationist, or foundationalist, approach would be literally illogical: the self-refuting trilemma faced by ‘supporting justifications’ (as regards arguments and evidence) is of entailing infinite regresses, dogmatic starting points, or circularities. Consequently, critical rationalism is assumed: conjecture and criticism are all that is possible. Thus all aspects of the conjectured thesis are explained and defended from criticism as thoroughly as the book can encompass. It is concluded that the thesis has not been refuted and so may be critically preferred. (However, this could all still be viewed as a ‘justification’ by those thus inclined.) All of this is made clear enough in the short introductory chapter and repeated where relevant throughout. Yet some reviews do not have a firm grasp of the specific project and so reject it with unsound criticisms. We now turn to one such example. (shrink)

Vallentyne 2010 and Zwolinski 2008 are internet encyclopaedia articles on “libertarianism” which include various serious faults. Vallentyne 2010 has the following ones. It does not properly explain mainstream libertarianism or consider criticisms of it. Instead, it mainly discusses self-ownership and natural-resource egalitarianism. Every aspect of the alleged “strict sense” of “libertarianism” is dubi ous, at best. So- called “left - libertarianism” is not made sense of as any kind of liberty-based libertarianism. Problems arise because self-ownership is assumed to be libertarian (...) without an explicit theory of libertarian liberty. The replies to “five impor tant objections to full self- ownership” are confused and mistaken; both as regards philosophical analysis and as regards empirical assumptions. The long discussion about various ways to “Appropriate Natural Resources” is rendered muddled and barren by the lack of a clear libertarian theory of liberty, the mere presumption of some form of egalitarianism, and the inclusion of various non-libertarian criteria. The remaining sections are largely uninformed by any relevant libertarian literature. It reaches a justificationist conclusion that cites mistaken welfare concerns and ignores the productivity of free markets. Zwolinski 2008 shares some errors with Vallentyne 2010, but also includes the following ones. It is even less clear about what libertarian liberty is. It fails to understand that libertarianism (private-property anarchy and, possibly, minarchy) is a subset of classical liberalism. It asserts that libertarianism is about “the proper role of government.” It assumes (illogical) justificationist/foundationalist epistemology and does not mention critical-rationalist libertarianism. It eventually faults justificationism and unwittingly assumes something approaching critical rationalism. Finally, it embraces John Rawls’s “overlapping consensus” as a “justification” (i.e., defence) of libertarianism oblivious to the similar position in Lester 1996 and 2000. (shrink)

La realtà del passato rappresenta uno dei principali problemi riguardanti la semantica giustificazionista proposta da Michael Dummett. L’antirealismo tipico di questa prospettiva determina una concezione del passato piuttosto controintuitiva secondo cui esso «cessa di esistere» quando non lascia tracce e testimonianze. In Truth and the Past, Dummett è tornato sulla questione abbandonando l’antirealismo sul passato con l’obiettivo di evitare questa concezione. Questa svolta rappresenta un inedito spostamento in direzione del realismo, limitato tuttavia dal netto rifiuto di aderire ad una nozione (...) di verità bivalente. Il mio intervento intende ricostruire e analizzare criticamente le ragioni di questa svolta di Dummett e cercare di sondare la solidità e la coerenza di questa rimodulazione del giustificazionismo.

Through his phenomenological approach, Husserl criticized the situation of science and called it a crisis. He aimed to suggest a way out of this crisis by presenting a philosophical program. However, restoring philosophy to its ancient unifying situation, saving science from this crisis, and giving it a human face, requires, according to critical rationalism, to consider the objectivity and rationality of science. Ignoring these considerations puts science on an incorrect and inconvenient path. These considerations require a revision of Husserl’s essentialism (...) and justificationsim, and placing truth as the aim of science. (shrink)
