Once and for all, there are many things I choose not to know.-Wisdom sets limits even to knowledge.

It is not enough to prove something, one also has to seduce or elevate people to it. That is why the man of knowledge should learn how to speak his wisdom: and often in such a way that it sounds like folly!

The foundation of our Empire was not laid in the gloomy age of Ignorance and Superstition, but at an Epoch when the rights of mankind were better understood and more clearly defined than at any former period, the researches of the human mind, after social happiness, have been carried to a great extent, the Treasures of knowledge, acquired by the labours of Philosophers, Sages and Legislatures, through a long succession of years, are laid open for our use, and their collected wisdom may be happily applied in the Establishment of our forms of Government.

Real knowledge is to know the extent of one's ignorance.

Share your knowledge. It is a way to achieve immortality.

The man of knowledge must be able not only to love his enemies but also to hate his friends.
