According to the seventh-century C.E. philosopher Kumārila Bhat.t.a, epistemic agents are warranted in taking their world-presenting experiences as veridical, if they lack defeaters. For him, these experiences are defeasibly sources of knowledge without the agent reflecting on their content or investigating their causal origins. This position is known as svatah prāmāṇya in Sanskrit (henceforth the SP principle). -/- As explicated by the eleventh-century commentator, Pārthasārathi Misŕa, this position entails that epistemic agents know things without simultaneously knowing that they know them, (...) or being in a position to know that they know. In contrast, some contemporary Anglo-analytic philosophers argue for the “knows-knows principle” (KK principle), in which if someone knows that p, then that person also knows that they know that p, or that person is in a position to know that they know p. Despite some apparent similarities, the SP principle is not a version of the KK principle, nor would Pārthasārathi’s Kumārila have held the KK principle. -/- Recently, Daniel Immerman (2018) has argued that the SP principle is a position-to-know version of the “knows-knows principle” (KK-pos principle). By examining Kumārila’s response to his Buddhist opponent, who challenges the veracity of Vedic testimony, we will see that Kumārila understands higher-order knowing as involving an independent check on one’s epistemic processes, through an epistemic instrument known as postulation (arthāpatti). This precludes him from holding the KK-pos principle. (shrink)

Tattvopaplavada, an ancient Indian school of scepticism, and Pyrrhonism, an ancient Greek school of scepticism, are the objects of examination of this paper because while, on the one hand, both attack the senses and reason as means of valid knowledge, on the other hand, both can serve as a basis for questioning Faith as the fount of human action. The aim of the paper is to examine how can these two schools of scepticism, which assert the impossibility of valid knowledge, (...) question faith without running into the risk of self-contradiction? Equally important is the question whether do they, in the process, commit the cardinal error of falling into the trap of self-reference? The aim of the paper is to examine the accusation of the critics of Scepticism that in the absence of certain basis of knowledge, human action is impossible. p { margin-bottom: 0.1in; direction: ltr; line-height: 115%; text-align: left; orphans: 2; widows: 2}a:link { so-language: zxx}.

In lieu of an abstract, here is a brief excerpt of the content:Some Ideas Concerning Stephen Phillips' Jewel of Reflection on the Truth about Epistemology:A Complete and Annotated Translation of the Tattva-cintā-maṇiEberhard Guhe (bio)Stephen Phillips' Jewel of Reflection on the Truth about Epistemology (see Phillips 2020) is surely a landmark achievement in the realm of research on Navya-Nyāya. It is a work of reference not only for specialists but also for a broader audience of philosophically interested readers. Phillips has demonstrated (...) his expertise on Nyāya in general in many previous publications. At present, there is probably hardly anybody else who would have been better qualified to accomplish the mammoth task of translating and elucidating such a complex and voluminous Sanskrit work as the Tattvacintāmaṇi. It should however be noted that there is another edition and annotated translation of the Tattvacintāmaṇi (excluding the Upamānakhaṇḍa) by V.P. Bhatta (see Bhatta 2005, 2012, 2021), which is rather addressed to specialists, who are proficient in Sanskrit. The two volumes on the Anumānakhaṇḍa were published in 2021 (one year after the publication of Phillips' three volumes). Considering the enormous size of such a book project, the result cannot be expected to be completely flawless. The present review focuses on the introduction in volume 1 and on volume 2. I will address some minor issues, primarily methodological ones, but I will also address a few more serious (albeit surely accidental) translation errors (especially in the Siddhāntalakṣaṇa-section of the Vyāptivāda), which can lead to a misunderstanding of Gaṅgeśa's stance on a pivotal topic of the Navya-Naiyāyikas, namely the correct definition of the concept of pervasion (vyāpti).IThe introduction is very insightful. However, logicians will probably stumble over Phillips' methods of formalization. Some examples are given below. [End Page 498](1) The language of Phillips' formalizations looks a bit like a first-order language. Thus, for example, he uses "Ha" as a formal equivalent of the sentence "The mountain is smoky" (see vol. 1, p. 18). An obvious deviation from first-order conventions consists in the fact that Phillips uses at least two types of negation. Propositional negation is expressed by means of the symbol "~" (see vol. 2, p. 668; unfortunately, this symbol is not mentioned in vol. 1, pp. 18–19, where Phillips introduces his formalization techniques). Moreover, Phillips uses the negation symbol "¬," which he applies to capital Roman letters, in order to express a kind of term negation. Thus, for example, "¬H" may serve as a term referring to "the absence of the probans" (vol. 2, p. 623). To be precise, the type of absence which "¬H" refers to is a so-called "relational absence" (saṃsargâbhāva). Phillips formalizes the so-called "mutual absences" (anyonyâbhāva) differently (see below).Although "¬Hc" (see vol. 1, p. 18) looks like an ordinary first-order wff, it should more accurately be read as "The absence of H is located at c." Properly speaking, we should then also read atomic wffs like "Hc" as "H is located at c," where "H" should not be regarded as an expression of a predicate like "… is smoky," but rather as a general term, that is, as a formal counterpart of expressions like, for example, "smoke."Unfortunately, Phillips renders the meaning of wffs of the form "¬ϕx" not as "the absence of H is located at x," but in a somewhat simplified manner, which obscures the fact that he treats the negation symbol "¬" as a means to express a term negation: "And negation is term negation, not propositional negation [author's note: as we have just seen, this is not true of all kinds of negation which Phillips refers to in his formalizations, since he uses the "~" in a different sense]; thus, the negative sign '¬' in '¬ϕx' is defined as 'ϕ is absent at x'" (vol. 1, p. 19).Moreover, the use of different kinds of letters for the variables in "¬ϕx" (Greek and Roman) seems to suggest that the absentee should always be the referent of a general term. However, expressions of the form "the absence of a is... (shrink)

This chapter is about a classical Indian debate about the Independent Check Thesis, the thesis that, if an agent is to rationally believe (or judge) that she knows that p, she must rely on some source of information that provides her independent evidence about the truth or reliability of her belief (or judgement) that p. While some Buddhists and Nyāya philosophers defended this thesis, the Bhāṭṭa Mīmāṃsakas rejected it. Here, I reconstruct the Bhāṭṭa Mīmāṃsakas’ arguments against the Independent Check Thesis. (...) I show that these arguments reveal a tension between this thesis and a plausible principle that connects knowledge and action. (shrink)

This paper briefly reviews highlights from decades of debates in medicine, law, bioethics, psychology and social research about children’s and parents’ views and consent to medical treatment and research. There appears to have been a rise and later a fall in respect for children’s views, illustrated among many examples by a recent book on the zone of parental discretion, which is reviewed. A return to greater respect for children’s views and consent is advocated.

In this paper we introduce a poset of subvarieties of BL-algebras, whose completion is the entire lattice of subvarietes; we exhibit also a description of this poset in terms of finite sequences of functions on the natural numbers.

This paper explores the philosophical aspects of the "Great Introduction" of Abū Ma'šar, one of the great figures of Arabic astrology and an associate of al-Kindī, the great 9th century philosopher. I argue that the following points of philosophical interest may be found in this text: 1. Astrology is described as a "master science" along the lines proposed by Aristotle, i.e. it provides principles for lower sciences. Also he supplies arguments to ground astrology on methodological grounds, such as the use (...) of empirical evidence and testimony. 2. Abū Ma'šar broadly follows al-Kindī's explanation of how the stars influence the sublunary world, by heating the elements. This agrees with al-Kindī's work "On the Proximate Agent Cause of Generation and Corruption," and I identify some parallels between the two works. 3. Finally, Abū Ma'šarr considers whether human freedom is compatible with this causal account. He holds that human actions do fall under the class of the "possible" and not the "necessary," but only because for him the "possible" is what happens sometimes, not always. Thus he seems tacitly to hold that genuine choice is compatible with causal necessitation. (shrink)
