Bernard Bolzano

Kierkegaard, like Plato, though using different methods and conclusions, sought to ground knowledge in the ineffability of subjectivity. For Plato, knowledge comes subjectively (internally); for Kierkegaard, it comes by God's grace through faith. Socrates becomes the facilitator for the slave in the /Meno/, as does God for the man of faith. Again, Kierkegaard is also concerned with passion. "...the paradox is the passion of thought, and the thinker without the paradox is like the lover without passion; a mediocre fellow" (p. (...) 37). The paradox is necessitated by the metaphysical nature of the inquiry. Only knowledge through faith can approach the paradox since it is by definition beyond our knowledge. Passion must accompany the leap of faith, since knowledge acquisition for the man of faith is guided by God. (shrink)

Brentanians defend the view that there are distinct types of object, but that this does not entail the admission of different modes of being. The most general distinction among objects is the one between realia, which are causally efficacious, and irrealia, which are causally inert. As for being, which is equated with existence, it is understood in terms of “correct acknowledgeability.” This view was defended for some time by Brentano himself and then by his student Anton Marty. Their position is (...) opposed to Bolzanian, Husserlian, and Meinongian ontologies, in which a distinction in the (higher) types of object implies a distinction in their mode of being. These Austro-German discussions anticipate much of the contemporary debate between Quineans, who accept only differences in objects, and neo-Meinongians or other ontological pluralists, who accept different modes of being. My paper first presents the Brentanian view in detail and then evaluates its philosophical significance. (shrink)

This thesis presents a Bolzano whose genius resulted not from his freedom from powerful philosophical influences, but precisely from his response to the powerful philosophical influences of his day. Chief amongst these were the voices engaged in debate about the nature of science. It was precisely Bolzano's commanding synthesis of the views of those advocating progress through mathematical physics with the views of those advocating a classical model of a science as the study of causes that set the stage for (...) the development of Austrian and analytic philosophy in subsequent centuries.
