In addition to serving as Princeton’s president from 1868 to 1888, Scottish-born philosopher James McCosh wrote the treatise Psychology: the Cognitive Powers in 1886. One of his lesser works, the book is broken into three sections that aim to explain various cognitive processes including the accumulation of knowledge, sense perception, and self-consciousness. Much of McCosh’s work sought to reconcile Darwin’s theories of evolution with the dogma of Christianity as an example of divine design. The complexities of the human mind proved no different.
