The four stages of life are infancy, childhood, adolescence, and obsolescence.
I have no duty to be anyone's Friend and no man in the world has a duty to be mine. No claims, no shadow of necessity. Friendship is unnecessary, like philosophy, like art, like the universe itself (for God did not need to create). It has no survival value; rather it is one of those things which give value to survival.
The value for which P=0.05, or 1 in 20, is 1.96 or nearly 2; it is convenient to take this point as a limit in judging whether a deviation ought to be considered significant or not. Deviations exceeding twice the standard deviation are thus formally regarded as significant. Using this criterion we should be led to follow up a false indication only once in 22 trials, even if the statistics were the only guide available. Small effects will still escape notice if the data are insufficiently numerous to bring them out, but no lowering of the standard of significance would meet this difficulty.
See what's inside a drop of water. The whole seed of the universe. Come, come. See what's inside a drop of blood. The composition of life. It's all there. Hate as well. We approach the mystery of life, but it's impossible to understand the mystery of hate. The kind of hate that causes people not only to kill, but to want to erase you from the census of births. I have to concentrate on that mystery. Read everything there is. It has to be in a drop of blood. It has to have its chemistry.
