In biographies of philosophers, a turning point often occurs in or around the fortieth year of life. This complies with a tradition of long standing, represented by Apollodorus of Athens for instance, who claims that, intellectually, philosophers experience their maximum, their acme (ἀκμή), around the age of forty. Plato founded his Academy in Athens ca. 387 B.C., when he was forty years old. My suggestion is to continue to pay attention to this rule. Around their fortieth birthday, prominent philosophers still tend to publish their first major, ground-breaking book.
