252 JOURNAL OF THE HISTORY OF PHILOSOPHY 22:2 APR 1984 definitions (Erkliirungen), which tie neatly distinguishes from propositions (Urteile, 2~, 38). Even modal logic is affected by Bolzano's interest in concepts and their composition . Possibility is not a property of sentences but of concepts (26, line 3o); the sentence "A can be B" in fact is understood as "A cure B is possible" (42). Because of the lack of commutativity of the A cure B form, the modal sentence "A can be B" fails to be convertible (2 t). For friends of the history of logic the volume offers a beautiful gift: Bolzano's statement of his plan to write a new logic, the Wissenschaflslehre. There is a preliminary outline of chapters and sections of this opus magnum, including a reference to the notion of" "objective truth" (later on "truth in itself"). The reader who takes seriously this notion of objective truth in Bolzano may want to test his understanding of it with the passage, to me unclear, on 15~ (between lines 3~ and 35), where Bolzano seems to claim that sentences of the form "If X has the property M, then X has the property N" (X being an lndividuum) are not objective truths. The physical appearance of the text is dreadful; every page boasts an overwhelming number of brackets and auxiliary philological symbols that, commendable or unavoidable as they may be for an edition of an abbreviated manuscript, do not encourage a continuous, relaxed reading. Reading this journal recalls driving on a cobblestone road. The volume contains a useful bibliography and helpful indices of names and topics.
