I have just three things to teach: simplicity, patience, compassion. These three are your greatest treasures.

Men are born ignorant, not stupid. They are made stupid by education.

The whole of science is nothing more than a refinement of everyday thinking.

When you know better you do better.

Education is a system of imposed ignorance.

For a successful technology, reality must take precedence over public relations, for Nature cannot be fooled.

The real solution lies in a world in which charity will have become unnecessary.

Education is the kindling of a flame, not the filling of a vessel.

A little knowledge that acts is worth infinitely more than much knowledge that is idle.

The delight of opening a new pursuit, or a new course of reading, imparts the vivacity and novelty of youth even to old age.

Any man who reads too much and uses his own brain too little falls into lazy habits of thinking.

Education is an admirable thing, but it is well to remember from time to time that nothing that is worth knowing can be taught.

A little knowledge is a dangerous thing. So is a lot.

Any knowledge that doesn't lead to new questions quickly dies out: it fails to maintain the temperature required for sustaining life.

Technology is just a tool. In terms of getting the kids working together and motivating them, the teacher is the most important.

The secret of life is not enjoyment but education through experience.

Don't worry that children never listen to you; worry that they are always watching you.

There is nothing more awful, insulting, and depressing than banality.

The deepest sin against the human mind is to believe things without evidence.

If you can't explain it simply, you don't understand it well enough.

That men do not learn very much from the lessons of history is the most important of all the lessons that history has to teach.
