Originally published in 1969. This book examines the fundamental concepts of metaphysics and of theory of knowledge. Topics treated include the nature of substance and of causation; their relation to natural laws, dispositions, and attributes; the nature of consciousness and purposiveness; of symbols, signs, and signals, and their relation to interpretation and objective reference; and the nature and criteria of truth. The author holds that philosophy is by intent a science and that its becoming so requires precise and non-arbitrary semantical (...) analysis of basic philosophical terms. He argues that philosophy then, like the other sciences, has practical importance: in its case this consists in its capacity to give to difficult practical decisions not only the efficacy insured by its application of the findings of the other sciences, but in addition some of the wisdom which is philosophy’s distinctive ultimate aim.

Jane Roland is evidently right when she points out that "knowing the rule" or "knowing that one ought" sometimes does and sometimes does not constitute having a tendency to behave according to the rule; and right also in her claim that when it does the contradiction she mentions between knowing the rule and frequently disobeying it arises. But the distinction she offers between a tendency and a capacity is not defensible.
