This volume shows how late medieval dream-poetry explored problems arising from the reception of Aristotle's philosophical work concerning human knowledge. Marco Nievergelt explores how the work of three medieval poets in the genre of allegorical fiction addressed these problems in distinctive, non-academic terms.

Körner's notion of vagueness, its relation to ostension and the alledged gulf between logic and experience are examined. Ostension is seen not to cause vagueness ~ there are precise concepts of mathematics which can be ostensively introduced. A distinction is drawn between classical logic not applying to the vague world and not applying to the vague language. The claims about logic and the vague world are unverifiable claims about existence. Körner's attempt to elimmate the seeming incompatibility between vague language and (...) logic leads to a Protagorean relativism which is rejected. It is denied that the incompatibility between vagueness and classical logic causes a gulf between two sublanguages; instead, ordinary language is held to contain both and so to be inconsistent.

This interesting volume offers sustenance to almost all who have an appetite for the problems of practical reason. As the Proceedings of the First Bristol Conference on Critical Philosophy, it contains the five papers presented there, with the remarks of commentators and, in three cases, replies. First, the bill of fare.Roderick Chisholm opens with “Practical Reason and the Logic of Requirement”, about which I shall say no more than to quote the beginning of G.E.M. Anscombe's comment: “It is characteristic of (...) Professor Chisholm to carry one always by a succession of small harmless-looking moves which then suddenly enable him to pull out some large kicking rabbits like a conjurer operating with a hat. This time he has produced the large kicking rabbits, but the initial movements do not seem as unsuspicious as usual.” Those who like what Chisholm does, will find fine detail in his paper, the comments, and his reply; unfortunately, for me Professor Chisholm's rabbits have the disconcerting invisibility of Harvey.
