Anselm of Canterbury’s so-called ontological proofs in the Proslogion have puzzled philosophers for centuries. The famous description “something / that than which nothing greater can be conceived” is part and parcel of his argument. Most commentators have interpreted this description as a definition of God. We argue that this view, which we refer to as “definitionism”, is a misrepresentation. In addition to textual evidence, the key point of our argument is that taking the putative definition as what Anselm intended it (...) to be – namely a description of a content of faith – allows getting a clear view of the discursive status and argumentative structure of Proslogion 2–4, as well as making sense of an often neglected part of the argument.

To consider metaphysical claims a priori and devoid of empirical content, is a rather commonplace received opinion. This paper attempts an exploration of a contemporary philosophical heresy: it is possible to test metaphysical claims if they play an indispensable role in producing empirical success, i.e. novel predictions. To do so one, firstly, needs to express the metaphysical claims employed in the logico-mathematical language of a scientific theory, i.e. to explicate them. Secondly, one should have an understanding of what it is (...) to test and to verify or to falsify a metaphysical claim. Finally, one also need to consider the philosophical practice of testing a metaphysical claim. These three aspects are introduced in this paper and they are illustrated by means of the metaphysical concept of common cause and the principle of the common cause. (shrink)

Pseudoproblems, pseudoquestions, pseudosentences (etc.) constitute an iridescent group of concepts which were prominently used by the Vienna Circle (including Wittgenstein). In the course of an explication this paper presents a compilation of the many different meanings that were given to these expressions. This includes the more prominent Viennese approaches as well as a more recent one by Roy Sorensen. A novel proposal concerning the use ofthe term is made, suggesting that nothing is just a pseudoproblem, but only relative to a (...) certain state of discourse. While the paper follows an explicative methodology, several uses of 'pseudoproblem', including the explicated one, relate pseudoproblemhood to other kinds of analysis. (shrink)

A characterization of epistemic rationality, or epistemic justification, is typically taken to require a process of conceptual clarification, and is seen as comprising the core of a theory of (epistemic) rationality. I propose to explicate the concept of rationality. -/- It is essential, I argue, that the normativity of rationality, and the purpose, or goal, for which the particular theory of rationality is being proposed, is taken into account when explicating the concept of rationality. My position thus amounts to an (...) instrumentalist position about theories of epistemic rationality. Since there are different purposes, or goals, for which theories of rationality are proposed, the method of explication leaves room for different characterizations of rationality. I focus on two such (kinds of) purposes: first, the purpose of guiding the formation (or maintenance) of doxastic states and, second, the purpose of assessing (the formation or maintenance of) doxastic states. I conclude by outlining a pluralistic picture concerning rationality. (shrink)
