The true sign of intelligence is not knowledge but imagination.

The goal of education is the advancement of knowledge and the dissemination of truth.

We first make our habits, and then our habits make us.

Knowledge is true opinion.

We are here and it is now. Further than that, all human knowledge is moonshine.

The aim of education is knowledge, not of facts, but of values.

Life can only be understood backward, but it must be lived forwards.

Learning never exhausts the mind.

Live as if you were to die tomorrow. Learn as if you were to live forever.

Tell me and I forget. Teach me and I remember. Involve me and I learn.
