The recently much discussed phenomenon of testimony as a social source of knowledge plays a crucial justificatory role in Richard Swinburne's philosophy of religion. Although Swinburne officially reduces his principle of testimony to the criterion of simplicity and, therefore, to a derivative epistemic source, we will show that simplicity does not play the crucial role in this epistemological context. We will argue that both Swinburne's philosophical ideas and his formulations allow for a fundamental epistemic principle of testimony, by showing that Swinburne has already implicitly justified the use of testimony as an epistemic source via his fundamental a priori principle of credulity.

In two recent papers in Studies in History and Philosophy of Science Howard Sankey has argued that there is an intimate relationship between Pyrrhonian skepticism and recent approaches to epistemic relativism.Though the general argument and idea of Sankey’s papers is very much appreciated, it is argued that the epistemic relativist’s recourse to the skeptical strategy outlined by the Pyrrhonian is not a good one. This diagnosis gives rise to an objection against the epistemic relativist who argues on the basis of the skeptical strategy that differs from Sankey’s naturalistic response. Furthermore, it can be shown that what is really at stake between epistemic relativism and epistemic absolutism is the question of which criteria there are for variation of epistemic norms and epistemic systems.

In this paper, I show that there are important but hitherto unnoticed similarities between key figures of the Vienna Circle and early defenders of sociology of knowledge. The similarities regard their stance on potential implications of the study of science for political and societal issues. I argue that notably Otto Neurath and Karl Mannheim are concerned with proposing a genuine political philosophy of science that is remarkably different from today’s emerging interest in the relation between science and society in philosophy of science

The paper focuses on one central aspect of Karl Mannheim’s sociology of knowledge: his exemption of the contents of mathematics and the natural sciences from sociological investigations. After emphasizing the importance of Mannheim’s contribution and his exemption-thesis to the history and development of the field and the problem of relativism, I survey several interpretations of the thesis – especially those put forward by proponents of the so-called ‘Strong Programme’. I argue that these interpretations do not get the philosophical background and impetus of Mannheim’s contribution right. By distinguishing between naturalistic and anti-naturalistic strands in Mannheim’s work I propose a new reading on which Mannheim did not exempt the contents of the areas in question principally or because of a lack of nerve and will. It is argued that Mannheim’s exemption-thesis rather is a consequence of his own sketchy sociological investigations of ‘the paradigm of the natural sciences’.
