ABSTRACT
[p. 15] Like biology and psychology, sociology is interesting, epistemologically, from two distinct but complementary viewpoints. First, sociology is a type of knowledge worthy of study in its own right, especially with regard to its relations (of difference as well as similarity) with psychological knowledge. Second, the very object of sociological knowledge is of vital interest to epistemology, since human knowledge is essentially collective, and social life constitutes an essential factor in the creation and growth of knowledge, both pre-scientific and scientific.
