Wittgenstein's work remains, undeniably, now, that off one of those few philosophers who will be read by all future generations.

Humanism, modernity, and scientific rationality are examined critically in these collected essays.

'The most thorough and scrupulous of contemporary students of induction' (the execrable Quinton 1993, p. 172).

Descartes made a sharp distinction between matter and mind. But he also thought that the two interact with one another. Is such interaction possible, however, without either a materialist reduction of mind to matter or an idealist (phenomenalist) reduction of matter to mind? These questions overshadow the Western tradition in metaphysics from the time of Descartes to present times. The book makes an effort to stay clear of reductivist views of the two Cartesian substances. It defends a dualistic psycho-physical parallel (...) theory which reconciles freedom of action with determinism in nature. Basic problems in perception theory are also discussed, with special emphasis on hearing and sound. Because of the intrinsic interest of the subject and the author's non-technical presentation of it, the book should appeal to all readers with a serious interest in philosophy and psychology.

_Zettel, _ an en face bilingual edition, collects fragments from Wittgenstein's work between 1929 and 1948 on issues of the mind, mathematics, and language.

For the last 25 years, since publication of his Logical Studies, Professor Von Wright has steadily explored the field of philosophical logic. The concept of negation, logical paradoxes, the puzzles connected with evidence and probability in confirmation theory, the interrelatedness of the ideas of time and change, and the clarification of the structure of temporal and spatial orderings are among the many areas he has profitably investigated. -- "Philosophical Review".

The paper is based upon a conception of norms as prescriptions which are neither true nor false. Two norms may be said to contradict one another when the conjunction of (the descriptions of) their contents is a logical contradiction. A norm is said to entail another norm when the first norm and the negation-norm of the second contradict one another. By the negation-norm of an obligation is understood a permission "to the contrary", and by the negation-norm of a permission an (...) obligation "to the contrary". On the basis of these definitions it can be shown that the axioms and theorems of first order standard deontic logic are "normative tautologies". Norms of higher order may be viewed as prescriptions "transmitting the will" of a higher or sovereign authority through a lower or sub-ordinate authority to the norm-subjects. Under this conception of the orders, it is provable that a "complete" system of deontic logic is S4-like. (shrink)
