The only source of knowledge is experience.
The true sign of intelligence is not knowledge but imagination.
To know is nothing at all; to imagine is everything.
A man should look for what is, and not for what he thinks should be.
Knowledge of what is does not open the door directly to what should be.
Imagination is more important than knowledge. For while knowledge defines all we currently know and understand, imagination points to all we might yet discover and create.
It is the supreme art of the teacher to awaken joy in creative expression and knowledge.
