Umphrey claims that his book is “[…] short on doctrine […] [and] does not, for example, present anything like a complete theory of natural kinds” and he offers instead a “map of the rugged conceptual landscape on which all natural philosophers today must proceed whether they like it or not” (10, cf. 158).	cache/expositions-2231.pdf	txt/expositions-2231.txt
