BOOK REVIEWS 389 From the perspective of this reviewer, the presently most obvious fault in this lecture lies in Putnam's criticisms of "the coherence theorists, Ludwig, et al." (p. 97). In this criticism, it is apparently assumed that the adequacy of their proposed solution to the problem considered must be judged solely on the basis of what is presently known. Since Putnam himself acknowledges that no satisfactory interpretation of quantum mechanics exists, this seems unwarranted. The superficiality of the criticism of this position makes this particularly notable . He states, for example, "to say that a wave gives an incomplete description of the state of a system is to say that systems whose state can be described by that wave function may really be in several quite different physical conditions." He then adopts the doubtful strategy of appealing to the meaning of completeness and incompleteness (they are not a matter of degree) in justification of the position that it is improper to say that a wave gives an incomplete descriptionl Despite the fact that, taken as a whole, his brief criticism of the coherence theory is somewhat ungracious. Putnam has set forth the principle issues sur~ rounding the problem with discerning lucidity. Paul K. Feyerabend, in "Problems of Empiricism," places a revisionist's version of empiricism in a carefully developed historical perspective. Empiricism as it has been known is both incomplete and weakened by undesirable assumptions. The incompleteness is to be removed by regarding empiricism as a cosmological hypothesis concerning the relation between man and the universe. The version of empiricism thus admitted has the character of a scientific theory. The undesirable assumptions are views no longer tenable of the nature and content of what is given in sense. Feyerbend understands sensations and perceptions as indicators on a par with indications of physical instruments, and likewise in need of interpretation . A philosophical method is proposed which requires theoretical pluralism instead of the theoretical monism that is (inappropriately) the ideal of much of contemporary empiricism (p. 149). The function of theoretical alternatives is to provide the means of criticizing accepted theory, to which he accords careful historical treatment. "Low level theories" are to guide us to crucial experiments, while "high level theories" are to represent the basic element of the universe. Here again the reader will find a theme which emerges erpeatedly in these lectures. This theme might be stated as follows. Both macrocosmic and microcosmic systems must ultimately be involved in scientific explanation. The crucial problem that emerges is how these two are to be related or in some degree integrated. By the way in which he develops the role of alternative theories, Feyerabend has affirmed one of the principle theoretical components of what Hegel was minded to call metaphysics. An additional observation, for which what I have said should furnish some justification: Many points made throughout this exposition (115 pp. in length) might properly be regarded as together constituting a rapprochement of empiricism and rationalism. It may very well occur to the thoughtful reader that Feyerabend, in his reconstruction of empiricism, has come very near to conceding all that a critical rationalist could ask. Other lectures included in the book are, "The Thermodynamics of Purpose," by David Hawkins, "The Physics of the Large," by Philip Morrison, and "The Ethical Dimension of Scientific Research," by Nicholas Rescher. In the last-mentioned lecture, Professor Rescher points up some generally little understood ethical problems confronted by the scientist in the practice of his profession. DARREL E.
