There are three kinds of brains: One understands of itself, another can be taught to understand, and the third can neither understand to itself or be taught to understand.
My fundamental premise about the brain is that its workings - what we sometimes call "mind" - are a consequence of its anatomy and physiology, and nothing more.
When you inquire 'Who am I?' if you are honest, you'll notice that it takes you right back to silence instantly. The brain doesn't have an answer, so all of a sudden there is silence.
I have never examined the subject of humor until now. I am surprised to find how much ground it covers. I have got its divisions and frontiers down on a piece of paper. I find it defined as a production of the brain, as the power of the brain to produce something humorous, and the capacity of percieving humor.
And so could you know it if you would only use the brains the good God has given you. Sometimes I really am tempted to believe that by inadvertence, He passed you by.
There are three kinds of brains. The one understands things unassisted, the other understands things when shown by others, the third understands neither alone nor with the explanations of others.
