“In a sense, words are encyclopedias of ignorance because they freeze perceptions at one moment in history and then insist we continue to use these frozen perceptions when we should be doing better.”

It has always surprised me how little attention philosophers have paid to humor, since it is a more significant process of mind than reason. Reason can only sort out perceptions, but the humor process is involved in changing them.

Sometimes the situation is only a problem because it is looked at in a certain way. Looked at in another way, the right course of action may be so obvious that the problem no longer exists.

Possibilities play a much bigger role in thinking than most people believe. Without possibilities you cannot make progress.

The awful thing is that you can never be aware of what you are not aware of.

The quality of our thinking will determine the quality of our future.

Mock the devil, and he will flee from thee.

Sometimes the situation is only a problem because it is looked at in a certain subjective, negative, ungrateful way.

What the joke displays is a switch in perception. This is important in changing the way we think.

I think school is a place where thinking should be taught.

I take things one step at a time.

I trust no one, not even myself.

The past is not a package one can lay away.

There’s one thing I’m really good at, and that’s hitting the ball over a net, in a box. I’m excellent.

Everyone in this room knows that Venus is probably one of the greatest people on the tour. She’s really great. She’s super professional. Complete opposite of me.

We all know who the real number one is. Quite frankly, I’m the best in the world.

One of the basic conditions for the victory of socialism is the arming of the workers Communist and the disarming of the bourgeoisie the middle class.

One of my proudest moments was probably 2013 Worlds because I proved to myself that I could do things that I didn’t think I could.
