This clearly written and finely argued text is based on a course taught by the late philosopher Yves Simon at The University of Chicago in 1958. The lectures and discussions were edited and published in 1965. This book handles the topic in six concise chapters which probe the problems confronting natural law theory in terms of definition, history, doctrine, and its future. The value of the text is heightened by Russell Hittinger's crisp introduction that focuses Simon's effort by noting, "Simon (...) believes that the greatest danger to the tradition of natural law is not its cultured critics, but rather the tendency of its allies to reduce natural law to an ideology in order to form a political or legal consensus about objective values". Despite this danger, which Simon outlines in detail, the distinction between ideology and philosophy need not imply a radical separation of the two, for "the content of an ideology is not necessarily at variance with the truth of philosophy".
