I maintain that among the main views concerning the central questions of epistemology (in particular, the question of justified belief) are evidentialism, (Pyrrhonian) scepticism and fideism. In this paper, I first present the arguments in favour of a form of evidentialism, according to which no false belief can be epistemically justified on the basis of evidence. Second, I consider the historical emergence of evidentialism during the period of the early Enlightenment. In particular, I explore the disagreement between Pierre Bayle and (...) Jean-Pierre de Crousaz, which demonstrates the emergence of the modern opposition between evidentialism and fideism. (shrink)

The cross-cultural differences in epistemic intuitions reported by Weinberg, Nichols and Stich (2001; hereafter: WNS) laid the ground for the negative program of experimental philosophy. However, most of WNS’s findings were not corroborated in further studies. The exception here is the study concerning purported differences between Westerners and Indians in knowledge ascriptions concerning the Zebra Case, which was never properly replicated. Our study replicates the above-mentioned experiment on a considerably larger sample of Westerners (n = 211) and Indians (n = (...) 204). The analysis found a significant difference between the ethnic groups in question in the predicted direction: Indians were more likely to attribute knowledge in the Zebra Case than Westerners. In this paper, we offer an explanation of our result that takes into account the fact that replications of WNS’s other experiments did not find any cross-cultural differences. We argue that the Zebra Case is unique among the vignettes tested by WNS since it should not be regarded as a Gettier case but rather as a scenario exhibiting skeptical pressure concerning the reliability of sense-perception. We argue that skepticism towards perception as a means of gaining knowledge is a trope that is deeply rooted in Western epistemology but is very much absent from Classical Indian philosophical inquiry. This line of reasoning is based on a thorough examination of the skeptical scenarios discussed by philosophers of the Indian Nyaya tradition and their adversaries. (shrink)

Atheism is skeptical towards gods, and atheology advances philosophical positions defending the reasonableness of that rejection. The history of philosophy encompasses many unorthodox and irreligious movements of thought, and these varieties of unbelief deserve more exegesis and analysis than presently available. Going back to philosophy’s origins, two primary types of atheology have dominated the advancement of atheism, yet they have not cooperated very well. Materialist philosophies assemble cosmologies that leave nothing for gods to do, while skeptical philosophies find conceptions of (...) god to be too unintelligible or unsupported by evidence to warrant credibility. The origins and genealogies of these two atheologies are sketched and compared over many centuries down to present-day atheism, which still displays signs of this internecine divide between confident naturalists and agnostic skeptics.

Drawing the complex terrain of the theories of induction and of the various ways to ground inductive knowledge in the middle ages is the aim of this paper. There have already been two excellent attempts to draw this terrain. The first is by Julius R. Weinberg and the second by E. P. Bos. My attempt differs from theirs in two major respects. The first is that it is more detailed in the examination of the various theories and their relations. The (...) second is that I focus on the role of natural necessities in induction. In particular, I try to place the various conceptions of induction within a network of issues that relate to the problem of universals, natural necessities and a power-based approach to activity in nature. Here is the road map. Section 2 explains Aristotle’s views of induction, as this were mainly developed in Posterior Analytics Book II.19 and states what I take it to be the main dilemma of induction, as this was described by Sextus Empiricus: induction is either perfect and impossible or imperfect and unjustified. In section 3, I move to Thomas Aquinas and his own attempt to justify induction and the actuality of general and necessary principles based on experience by an appeal to the natural light of reason. In section 4 I discuss John Duns Scotus’s reliance on a self-evident maxim to bridge the gap between imperfect and perfect induction. Section 5 moves to William of Ockham ’s peculiar attempt to justify single-instance inductions. Then, section 6 offers a detailed account of Jean Buridan’s ground-breaking re-conceptualisation of induction and the role of intellect in it. Section 7 discusses the critique of induction by Nicolaus of Autrecourt. Finally, section 8 offers a brief account of Pseudo-Scotus’s move from knowledge to opinion. (shrink)
