Abstract

The article discusses the position of the Australian philosopher David Armstrong on the problem of the ontological status of the laws of nature. Through a clarification of Armstrong’s understanding of naturalism, physicalism, and factualism, the general essence of his metaphysical project is summarized. Then article presents his theory of the laws of nature, which is a kind of nomological realism: his version of the nomolog­ical argument is examined; his general grounds for rejecting the regularity theories, which is classical for the naturalistic approach, are clarified; and the role of abduction in Arm­strong’s theory is demonstrated. The relation of nomic necessity, which is the key concept of his theory, is discussed in detail: its status as a second-order universal is explained; the terms of this relation, namely the types of states of affairs that constitute some special kind of universals, are distinguished; the essence of the nomic connection assumed by this relation is clarified through Armstrong’s theory of causality. Armstrong’s critique of regularity theories of laws of nature and the advantages of his nomological realism over them are discussed: cases where regularity is not law are considered; cases where there are laws that are not related to regularities, and cases where law and regularity seem to coincide, but there is reason to believe that they are different, these are the cases that appear to be most important. Finally, drawing on his own argumentation, the advan­tages of Armstrong’s theory over the best systems approach are justified: the problem of subjectivism and the threat of anti-realism inherent in coherentist approaches are ex­amined; the highly counterintuitive dependence of the existence of some laws on the ex­istence of others is pointed out; and the danger of actual contradictions within our ontol­ogy is demonstrated.
