The author's magnum opusFirst edition of this masterwork by Bolzano, "a towering figure in the epistemology, logic, and methodology of the first half of the nineteenth century" (Encyclopedia of Philosophy I, p. 338).
Bernard Bolzano (1781-1848) was a Roman Catholic priest and professor of the philosophy of religion at the University of Prague. "If there is any one predecessor whose work he may be said to follow with admiration, that is 'the great Leibniz'. But it may be that when he called his chief work Wissenschaftslehre he had in mind both the medieval account of logic as ars artium and also Leibniz's talk of a scientia generalis that would deal with the organization of the sciences. For the title means 'theory of science' rather than 'theory of knowledge' (Erkenntnistheorie), and the sub-title of the original edition explains that the work is 'an attempt at a detailed and in large part new presentation of Logic with constant reference to those who have worked on it hitherto'. But the work is not concerned solely with formal logic. On the contrary it professes to deal with 'all the rules to be observed in the division of the whole realm of truth into separate sciences and in the presentation of these same sciences in special treatises' Discontent with Kant's talk of distinction between form and matter had made Bolzano doubtful of the possibility of drawing any clear line between the two. He wished to separate logic from psychology and rhetoric and to insist that possibility is not to be confused with conceivability, but he thought that logic must take account of the different ways in which we come to knowledge and that it could not consist solely of analytic truths, as those conceived by Kant, since such truths would not be important enough to make a science. There is, he holds, a sense in which logic may be described as formal because it deals with forms or patterns of inferences, but this does not justify us in excluding from the scope of logic such distinctions as that between judgements a priori and judgements a posteriori (in the sense which Kant gave to those phrases)" (Kneale & Kneale, p. 359f).
