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)
This considerably revised second edition of Wittgenstein's 1914-16 notebooks contains a new appendix with photographs of Wittgenstein's original work, a new preface by Elizabeth Anscombe, and a useful index by E.D. Klemke. Corrections have been made throughout the text, and notes have been added, making this the definitive edition of the notebooks. The writings intersperse Wittgenstein's technical logical notations with his thoughts on the meaning of life, happiness, and death. "When the first edition of this collection of remarks appeared in (...) 1961 we were provided with a glimpse of the workings of Wittgenstein's mind during the period when the seminal ideas of the _Tractatus Logico-Philosophicus_ were being worked out. This second edition provided the occasion to be struck anew by the breadth, rigor, and above all the restlessness of that mind."—T. Michael McNulty, S. J., _The Modern Schoolman_. (shrink)
