Quine's well-known ‘Two Dogmas of Empiricism’ (1951) plays a key role in the debate about the analytic-synthetic distinction. Taking to task the ideas of Carnap in particular, Quine shows that logical positivism works with a concept of scientific rationality that is based dogmatically on, among other things, the opposition analytic-synthetic.

Does logic describe something or not? If not, is it a normative or practical discipline? Is there a radical division between the practical or normative level and the theoretical or descriptive level? A discipline is theoretical, we may say, if its main propositions contain descriptive expressions, such as “is” or “have”, but no normative expressions, such as “ought”, “ought not” or “may”. A discipline is normative if its main propositions are of the form “it ought to be”. Theoretical propositions express (...) what is, whereas practical propositions express what should be. So a theoretical discipline is descriptive and a normative discipline is prescriptive, but what does a theoretical discipline describe? (shrink)

: The paper is a detailed reconstruction of Bernard Bolzano's account of merely possible objects, which is a part of his ontology that has been widely ignored in the literature so far. According to Bolzano, there are some objects which are merely possible. While they are neither denizens of space and time nor members of the causal order, they could have been so. Thus, on Bolzano's view there are, for example, merely possible persons, i.e., objects which are neither actual nor (...) persons but which could have been both. In course of the development of Bolzano's views, they are contrasted with the better known theory of his compatriot Alexius Meinong, and it is shown that they have a modern counterpart in the accounts of merely possible objects that were developed by Bernard Linsky and Ed Zalta, and by Timothy Williamson.
