Friendship [PDF ebook] 
A History

This volume aims to combine an analysis of the major classical philosophical texts of friendship and their continuing importance over many centuries with a broader discussion of the changing ways in which friendship was understood and experienced in Europe from the Hellenic period to the present. It is the result of a collaborative research project that has involved philosophers and historians with special research interests in Classical Greek philosophy and in the history of medieval and renaissance, 18th century 19th and 20th century Europe.
