Three (apparent ) deontic antinomies are discussed: the paradoxes of the watchman and the praiser, as weIl as deontic dilemmas. A paraconsistent deontic logic, Ad, is put forward whose underlying 1st-order calculus is an infinite-valued tensorial logic. Several arguments are offered bearing out be existence of deontic contradictions, while two ways of dealing with conditional obligation paradoxes within the framework of Ad are canvassed. While the aggregation rule and the ought-implies-can principle are upheld, sundry schemata are shown not to obtain which involve iterated deontic operators (most conspicuously: that whatever ought to be obligatory is obligatory; and that it is obligatory that whatever ought to be the case should in fact be the case).

The main starting point of many of the contributions collected into the book is the kind of Twin Earth considerations, along with meaning individualism. Is Putnam's claim about water in this world and a stuff in an alternative world being different materials?. Is meaning in the head? One seems allowed to be skeptical about the starting point of the debate between such as emphasize broad content and those who think that the basic semantic entities are narrow contents, which would fail to be world-dependent or world-oriented. The kind of motivations prompting the essays collected into the book are likely to be regarded as in need of a deeper elucidation by such as have been more or less influenced by Quine. Pettit & McDowell's collection of essays is one of the books most scholars interested in the confines of philosophy of language and philosophy of mind will find worth reading.
