Huntington Cairns identifies the views that major Western philosophers took on law, the problems they considered significant about law, and the nature of the solutions they proposed. This book develops ideas discussed in Cairns' Law and the Social Sciences (1935) and Theory of Legal Science (1941). The object of these three volumes is the same: to construct the foundation of a theory of law that is the necessary antecedent to a possible jurisprudence. The inventory of philosophers that Cairns examines includes Plato, Aristotle, Cicero, Aquinas, Hobbes, Spinoza, and Hegel.
