What is remarkable about the Greeks - even pre-philosophically - is that despite the salience of religious rituals in their lives, when it came to the question of what it is that makes an individual human life worth living they didn't look to the immortals but rather approached the question in mortal terms. Their approaching the question of human mattering in human terms is the singularity that creates the conditions for philosophy in ancient Greece, most especially as these conditions were realized in the city-state of Athens.
