Publisher's Synopsis
Reinhardt Grossmann is one of the most sophisticated, knowledgeable and original contemporary metaphysicians. Although he was a student of Bergmann, he influenced the development of Bergmann's metaphysics considerably. No philosopher other than Grossmann defends perception to that degree against the persistent sceptical arguments. He characterises his epistemological positions as radical empiricism and radical realism. By realism Grossmann mainly means the view that the material things we perceive exist. It is thus also an ontological position and closely related to his empiricism. Grossmann's empiricism is radical insofar as he claims that entities of all categories are perceptible, even numbers and universals. Grossmann's universal realism advocates a theory of abstract categories against the current naturalism. He distinguishes between the world and the physical universe. The latter is the domain of science; the former is the subject of ontology.
