Nothing is too high for the daring of mortals: we storm heaven itself in our folly.

Horace

Misce stultitiam consiliis brevem:
Dulce est desipere in loco.

Mingle some brief folly with your wisdom.
To forget it in due place is sweet.

Horace 65 - 8 B.C.

To flee vice is the beginning of virtue, and to have got rid of folly is the beginning of wisdom.
Horace (65 BC - 8 BC), Epistles
