One trait in the philosopher's character we can assume is his love of the knowledge that reveals eternal reality, the realm unaffected by change and decay. He is in love with the whole of that reality, and will not willingly be deprived even of the most insignificant fragment of it - just like the lovers and men of ambition we described earlier on.
PlatoWelcome out of the cave, my friend. It's a bit colder out here, but the stars are just beautiful.
PlatoWhen the mind's eye rests on objects illuminated by truth and reality, it understands and comprehends them, and functions intelligently; but when it turns to the twilight world of change and decay, it can only form opinions, its vision is confused and its beliefs shifting, and it seems to lack intelligence.
