Let every man practice the art that he knows best.

. . . 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. Minds have been given to them out of the eternal fires you call fixed stars and planets, those spherical solids which, quickened with divine minds, journey through their circuits and orbits with amazing speed.

They condemn what they do not understand.

Whatever befalls in accordance with nature should be accounted good.

The wise are instructed by reason, average minds by experience, the stupid by necessity and the brute by instinct.

Thus nature has no love for solitude, and always leans, as it were, on some support; and the sweetest support is found in the most intimate friendship.

Sweet is the recollection of difficulties overcome.
