When the sufferers learn to think, then the thinkers will learn to suffer.

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

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

Even people who aren't geniuses can outthink the rest of mankind if they develop certain thinking habits.

The world as we have created it is a process of our thinking. It cannot be changed without changing our thinking.

There is nothing either good or bad but thinking makes it so.
