That laws of nature play a vital role in explanation, prediction, and inductive inference is far clearer than the nature of the laws themselves. My hope here is to shed some light on the nature of natural laws by developing and defending the view that they involve genuine relations between properties. Such a position is suggested by Plato, and more recent versions have been sketched by several writers.~ But I am not happy with any of these accounts, not so much (...) because they lack detail or engender minor difficulties, though they do, but because they share a quite fundamental defect. My goal here is to make this defect clear and, more importantly, to present a rather different version of this general conception of laws that avoids it. I begin by considering several features of natural laws and argue that these are best explained by the view that laws involve properties, that this involvement takes the form of a genuine relation between properties, and, finally, that the relation is a metaphysically necessary one. In the second section I start at the other end, and by reflecting on the nature of properties arrive at a similar account of natural laws. In the final section I develop this account in more detail, with emphasis on the nature of the relation between properties it invokes. Along the way several natural objections to the account are answered. (shrink)

This paper contains a discussion of a theory of laws of nature formulated recently by Michael Tooley. He sees the truth-makers for laws of nature as consisting of particular sorts of contingent relations between universals. He is not alone in this idea; it has also been advanced by Fred Dretske and D.M. Armstrong. However, its most thorough and detailed presentation is by Tooley. Being a challenging and stimulating idea, it merits investigation.

THE ARTICLE IS AN ATTACK ON THE MYSTERY OR REDUCTION DILEMMA FOR SUPERVENIENCE. THIS IS THE DILEMMA THAT EITHER SUPERVENIENCE IS MYSTERIOUS OR THE SUPERVENIENT IS REDUCIBLE TO THE SUBVENIENT. A NONMYSTERIOUS, NONREDUCTIVE ACCOUNT OF SUPERVENIENCE IS PROPOSED, BASED ON THE METAPHYSICAL SPECULATION THAT SUPERVENIENT TERMS AND PHRASES APPLY TO OBJECTS WHOSE INTRINSIC NATURES THEMSELVES HAVE AN APPROPRIATE PROPERTY. SINCE THIS IS A PROPERTY OF A NATURE IT IS A PROPERTY OF A PROPERTY, THAT IS, A GRAND-PROPERTY. SUPERVENIENCE FOLLOWS FROM (...) THIS HYPOTHESIS QUITE NONMYSTERIOUSLY, BY APPEAL TO THE INDISCERNIBILITY OF IDENTICALS. THE METAPHYSICAL SPECULATIONS REQUIRED MIGHT SEEM EXTRAVAGANT. A LARGE PART OF THE PAPER IS DESIGNED TO SHOW THAT THEY ARE NOT EXTRAVAGANT. (shrink)

An argument for realism (i.E., The ontological thesis that there exist universals) has emerged in the writings of david armstrong, Fred dretske, And michael tooley. These authors have persuasively argued against traditional reductive accounts of laws and nature. The failure of traditional reductive accounts leads all three authors to opt for a non-Traditional reductive account of laws which requires the existence of universals. In other words, These authors have opted for accounts of laws which (together with the fact that there (...) are laws) entail that realism is true. This argument for realism which emerges from the work of armstrong, Dretske, And tooley is discussed and criticized. Conclusions from the discussion question the tenability of all reductive accounts of laws. (shrink)
