. . . for until that God who rules all the region of the sky . . . has freed you from the fetters of your body, you cannot gain admission here. Men were created with the understanding that they were to look after that sphere called Earth, which you see in the middle of the temple.

Unbecoming to a gentleman, too, and vulgar are the means of livelihood of all hired workmen whom we pay for mere manual labour, not for artistic skill; for in their case the very wage they receive is a pledge of their slavery.
