The infinitely little have a pride infinitely great.

The right of commanding is no longer an advantage transmitted by nature; like an inheritance, it is the fruit of labors, the price of courage.

There are no sects in geometry.

Originality is nothing but judicious imitation. The most original writers borrowed one from another. The instruction we find in books is like fire. We fetch it from our neighbor's, kindle it at home, communicate it to others, and it becomes the property of all.
