Patience is a virtue, and I'm learning patience. It's a tough lesson.

Science is what we have learned about how to keep from fooling ourselves.

Knowledge is of two kinds. We know a subject ourselves, or we know where we can find information upon it.

Courage, conviction and confidence.

Education is a human right with immense power to transform. On its foundation rest the cornerstones of freedom, democracy and sustainable human development.

Reading without reflecting is like eating without digesting.

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

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

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

They say a little knowledge is a dangerous thing, but it's not one half so bad as a lot of ignorance.

Reading furnishes the mind only with materials of knowledge; it is thinking that makes what we read ours.

Learn as though you would never be able to master it; hold it as though you would be in fear of losing it.

Education is an ornament for the prosperous, a refuge for the unfortunate.

The most savage controversies are those about matters as to which there is no good evidence either way.

Science is a rising force, It is creating a new world about us. It needs to be watched and pressed into service, and in any case, it would be courting disaster to ignore it.

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

Opinion is the medium between knowledge and ignorance.

Knowing is not enough; we must apply. Willing is not enough; we must do.

Education is the most powerful weapon which you can use to change the world.

Reading is to the mind what exercise is to the body.

Science is a way of thinking much more than it is a body of knowledge.
