Sayings of Socrates 42

He could afford to despise those who scoffed at him. He prided himself on his plain living, and never asked a fee from anyone. 

He used to say that he most enjoyed the food which was least in need of condiment, and the drink which made him feel the least hankering for some other drink; and that he was nearest to the gods in that he had the fewest wants. 

This may be seen from the Comic poets, who in the act of ridiculing him give him high praise. Thus Aristophanes:

O man that justly desirest great wisdom, how blessed will be thy life amongst Athenians and Greeks, retentive of memory and thinker that thou art, with endurance of toil for thy character; never art thou weary whether standing or walking, never numb with cold, never hungry for breakfast; from wine and from gross feeding and all other frivolities thou dost turn away. 

Ameipsias too, when he puts him on the stage wearing a cloak, says:

a. You come to join us, Socrates, worthiest of a small band and emptiest by far! You are a robust fellow. Where can we get you a proper coat?
b. Your sorry plight is an insult to the cobblers.
a. And yet, hungry as he is, this man has never stooped to flatter. 

This disdainful, lofty spirit of his is also noticed by Aristophanes when he says:   

Because you stalk along the streets, rolling your eyes, and endure, barefoot, many a hardship, and gaze up at the clouds. 

And yet at times he would even put on fine clothes to suit the occasion, as in Plato's Symposium,where he is on his way to Agathon's house.
