FARMINGTON — Jonathan Cohen, a philosophy professor at the University of Maine at Farmington, will give a talk and sign copies of his new book, “Science, Culture, and Free Spirits,” on Thursday, Oct. 7, at Devaney Doak & Garrett Booksellers.

In this insightful study, Cohen, a Nietzsche specialist, argues that “Human, All Too Human” represents the crucial watershed for Nietzsche’s philosophical development, the moment at which he “becomes who he is.”

The signing will be at 7 p.m. in the book store in the downtown.
