Within ontology new theories are extremely rare. Hacking bravely claims to have one: "historical ontology" or "dynamic nominalism." Regrettably, he uses "nominalism" idiosyncratically, without explaining it or its qualifier. He does say what historical ontology is: it is "the presentation of the history of ontology in context." This idea is laudable, as it invites presenting idealism as once attractive but no longer so (due to changes in perception theory, for example). But this idea is a proposal, not a theory, muchless an ontological theory, as it does not say what things are made of. Also, Hacking's details are often misleading. Thus, he falsely hints that he respects Wittgenstein and that he agrees with him. Considered as a study of ontology sans its (often amusing) incidental material, it appears surprisingly thin and repetitious. The study is either excessively opaque or quite clear but stale: the choice between these options is open. Key Words: Ian Hacking • Michel Foucault • ontology • contextualism.

The word "brain-washing", translated from Chinese communist jargon, is a very strong metaphor, first popularized by Robert Jay Lifto n. It vividly describes one person interfering with the personality make-up of another, removing the other's ideology and replacing it, and similarly tampering with the other's tastes, pool of information to rely upon and whatever else goes into the make-up of the other's personality. Clearly, in some sense or another everyone interferes with the personality of people with whom they interact; yet what is meant here is something much more drastic than friends influencing one another's tastes or opinions; it is something more dramatic and more large scale.

The idea of verisimilitude is implicit in the writings of Albert Einstein ever since 1905, when he declared the distribution of field energy according to Maxwell's theory an approximation to that according to quantum-radiation theory, and Newtonian kinetic energy an approximation to his relativistic mass-energy. All his life Einstein presented new ideas as yielding older established ones as special cases and first approximations. The news has reached the philosophical community via the writings of Sir Karl Popper half-a-century after Einstein's trailblazing conception — first in his epoch-making "Note on Berkeley as a Precursor to Mach" and then in his classic "Three Views Concerning Human Knowledge"

In lieu of an abstract, here is a brief excerpt of the content:92 A NOTE ON SMITH'S TERM "NATURALISM" The reader of contemporary Hume literature may feel exasperated when reading recent authors. A conspicuous example is A.J. Ayer (Hume, 1982; see index, Art, Natural beliefs), who declares they endorse Kemp Smith's view of Hume's "naturalism" without sufficiently clarifying what they — or Smith — might exactly mean by this term. Charles W. Hendel, in the 1963 edition of his 1924 Studies in the Philosophy of David Hume, adds eight pages of a new preface and thirty-one pages of a review of Hume scholarship between 1925 and 1962, and he speaks at great length there of his life-long friendship and cooperation with Norman Kemp Smith and appreciation of his work. He says (p. xlviii), "There is a disposition today to assimilate Hume's thought to naturalism as understood in the contemporary sense." He does not say what this "contemporary sense" is, and the statement just quoted seems to have served as the seal of approval and the legitimation of this questionable practice. Hendel's new, 1963, material mentions Smith's discussion of Hume's "naturalism" — but refers only to Smith's early work, "The Naturalism of Hume," Mind, 14, 1905, 149-173 and 335-347, not to Smith's famous The Philosophy of David Hume of 1941, even though he deems that work "of great consequence for Hume scholarship" (p. xxxviii) and a "masterwork" (p. xxxix). The early work (1905) of Smith is already mentioned by Hendel in the body of the 1924 work (p. 361), although there, clearly, the word "naturalism," whatever its meaning is, and however contemporary then, is not necessarily the "contemporary sense" of 1962. The work which clearly (if implicitly) distinguishes between the traditional sense and Smith's 1905 sense of "naturalism" is John Laird's Hume's 93 Philosophy of Human Nature, 1932, 1967. We find there a discussion of Hume's naturalism (beginning of Chapter II), as well as of Hume's "Naturalism" (Chapter VI, fifth and fourth paragraphs from the end), with reference to Smith's 1905 work. Now, the traditional sense of "naturalism" is straightforward and seems to have been instituted by Pierre Bayle to designate the view of the world as devoid of all supernatural intervention, the view of the world as "disenchanted," to use the equivalent term accredited to Max Weber. Clearly, all Epicureans and neoEpicureans, Hume included, were naturalists in this sense. This is not the sense in which Smith uses it in his 1905 essay, "The Naturalism of Hume." The first part of this essay opposes T. H. Green's traditional reading of Hume as a philosopher who streamlined the ideas of Locke and Berkeley and proposes to replace it with the view of Hume's view as "naturalism." "Hume's... naturalistic view of reason," we are told (p. 158), "is a new theory of belief": Humean belief, on Smith's new reading, "is not caused by knowledge but precedes it, and as it is not caused by knowledge it is not destroyed by doubt" (p. 165). Smith declared his reading quite revolutionary, yet it may be endorsed without rejecting Green's reading. Smith does not even attempt to re-interpret in detail the passages which prima facie conform to Green's reading. The second part of his essay is the application of his revolutionary reading to psychology and to ethics. Smith devotes the preface of his The Philosophy of David Hume (1941) to a revision of his 1905 study. It seems he did not alter his attitude towards the first part but only to the second: he thought the starting point of Hume's study was his concern not for "naturalism" but for "moral philosophy, or the science of human nature" (opening words of Hume's Inquiry, cf. Hendel, op. cit., p. xlvi). This statement has to do 94 with emphasis, not with the meanings of terms or with ascriptions of views (and it is erroneous, or at least limited; but this is another matter). This is not to deny that Hume was a naturalist in Bayle's sense, as everyone today agrees. Most philosophers today share this naturalism with Hume. "His attitude and way of...

Both a Popper biography and an autobiography, Agassi's "A Philosopher's Apprentice" tells the riveting story of his intellectual formation in 1950s London, a young brilliant philosopher struggling with an intellectual giant - father, mentor, and rival, all at the same time. His subsequent rebellion and declaration of independence leads to a painful break, never to be completely healed. No other writer has Agassi's psychological insight into Popper, and no other book captures like this one the intellectual excitement around the Popper circle in the 1950s and the struggles of the 1960s and 1970s - personal, academic, political, all important philosophically. Agassi's Popper - whether one agrees with it or not - is an enormous contribution to scholarship. This second revised edition includes also Popper's and Agassi's last correspondence and, in a postscript it shows Agassi leafing through Popper's archives, reaching a sort of reconciliation, an appropriate ending to the drama. A must read. Malachi Hacohen, Duke University.
