A summary of these three philosophers on the subjects of the limitation of rational-conceptual knowledge and of the necessity for what the author calls "supra-rational" knowledge. Pascal is used as a standard for the other two, due to his full commitment to suprarational knowledge in the Christian revelation.--R. D. P.

Twelve essays from a symposium concerned with the influence of relativistic concepts on the development of the social sciences. There is general agreement that methodological relativism, though often appropriate to scientific inquiry, has lead to a normative relativism which is inappropriate to the study of man.--R. D. P.

A journal, many of whose articles bring Thomistic philosophy to bear on non-Thomistic traditions, philosophical and otherwise, in a scholarly and sympathetic fashion.--R. D. P.

A text covering twenty-nine ethical systems from Plato to Stevenson. Each essay treats one thinker and is liberally seeded with quotations from his major works. Thinkers are grouped according to schools of thought.--R. D. P.

A collection of papers delivered at a colloquium in 1960. Most are quite brief; all are at a rather high level of technical sophistication. Of general interest are L. Apostel's "Toward the Formal Study of Models in the Non-Formal Sciences," which concludes that a unique definition of models in terms of their function should be the basis for a general description of this "multiform concept"; H. Freudenthal's discussion of "models in Applied Probability"; a historical treatment of "Model and Insight" by (...) A. Kuipers; and P. Suppes's "Comparison of the Meaning and Uses of Models in Mathematics and the Empirical Sciences," which stresses the "set-theoretical" notion of model and emphasizes the possibility of greater formalization of the empirical sciences through the former. Among other authors represented are E. W. Beth, J. L. Destouches, and J. B. Ubbink.--R. D. P. (shrink)

The general topic is morality, divided into three notions, Action, Wisdom and Grace. The lectures are lively historical reflections on these notions seen in the context of Greek thought, especially that of Plato and Aristotle.--R. D. P.
