The starting point of the article is that the contemporary English written philosophy of friendship is strongly inspired by Aristotelian theory of friendship and considers this theory as the most influential among ancient theories. The starting point is illustrated in the first part of the article by general and specific examples. Second and main part aims to examine justification of such a primacy of Aristotle’s inspirations in contemporary philosophy of friendship. The verification is performed through comparison of qualities of Aristotle´s theory and theories of other ancient philosophers – Plato, Cicero and Plutarch.
