“Marry, and you will regret it; don’t marry, you will also regret it; marry or don’t marry, you will regret it either way. Laugh at the world’s foolishness, you will regret it; weep over it, you will regret that too; laugh at the world’s foolishness or weep over it, you will regret both. Believe a woman, you will regret it; believe her not, you will also regret it… Hang yourself, you will regret it; do not hang yourself, and you will regret that too; hang yourself or don’t hang yourself, you’ll regret it either way; whether you hang yourself or do not hang yourself, you will regret both. This, gentlemen, is the essence of all philosophy.”
― Søren Kierkegaard

“Although we know the end of the maze holds death (and it is something I have not always known--not long ago the adolescent in me thought death could happen only to other people), I see now that the path I choose through that maze makes me what I am. I am not only a thing, but also a way of being--one of many ways--and knowing the paths I have followed and the ones left to take will help me understand what I am becoming.”
― Daniel Keyes, Flowers for Algernon

“That's the thing about human life--there is no control group, no way to ever know how any of us would have turned out if any variables had been changed.”
― Daniel Keyes, Flowers for Algernon

“The value of a physical theory depends upon its usefulness. In this sense the history of physical theories might be said to resemble the history of individual personality traits. Most of us respond to our environment with a collection of automatic responses that once brought desirable results, usually in childhood. Unfortunately, if the environment that produced these responses changes (we grow up) and the responses themselves do not adapt, they become counterproductive. Showing anger, becoming depressed, flattering, crying, and bullying behavior are response patterns appropriate to times often long past. These patterns change only when we are forced to realize that they are no longer productive. Even then change is often painful and slow. The same is true of scientific theories.”
