The present text book is intended as an introduction to elementary logic. Its content, structure, and manner have been determined in large measure - perhaps 'caused' is the better word- by certain desiderata about which the reader should be informed at the outset. The leading idea is that even an introductory treatment of logic may profitably be fashioned around a rigorous framework.

This is the first, and indeed the definitive systematic account of the wide-ranging philosophical ideas of Leibniz. The author, a highly respected analytical philosopher, has brought his own formidable abilities to bear on the unwieldy and inaccessible corpus of Leibniz's work.

A study of Pyrrhonean scepticism, consisting of a new translation of Sextus Empiricus' Outlines of Pyrrhonism, accompanied by an analytic introduction and an in-depth, section-by-section commentary - the first of its kind available.

"In philosophy," the author writes in his preface, "we have learned to get our satisfaction from showing that the other fellow is mistaken rather than from establishing the truth of our own positive tenets." The impeccably professional work of a mature and distinguished logician and scholar, Skeptical Essays propounds the view that the principal traditional problems of philosophy are genuine intellectual knots; they are intelligible enough, but at the same time the are absolutely insoluble. The problems Mates discusses are: the (...) Liar paradox and Russell's Antinomy of the class of all nonself-membered classes; the problem of determinism and moral responsibility; and the existence of the external world. Clearly written and effectively organized, the book will be an excellent text for advanced students. (shrink)

Philosophers have given various reasons for denying the existence of sense data. A number of these reasons are examined in the present paper. The claim that ?no sufficient purpose is served by positing such objects? is deemed irrelevant to the issue; the complaint that ?we do not know what it would be like to find that there were no such objects? is found to be confusedly formulated, mistaken, and irrelevant; and the charge that there is something improper, extraordinary, or defective (...) about the way in which philosophers have introduced the term ?sense datum? into their discourse is pronounced false.
