We know that to wage a nuclear war today, for example, would be a form of suicide; or that to pollute the air or the oceans in order to achieve some short-term benefit would be to destroy the very basis for our survival.
I am perfectly confident that I could never adequately convey to any other human being the precise reasons why I continue to refrain from suicide - the reasons, that is, why I still find existence enough of a compensation to atone for its dominantly burthensome quality.
Irrevocable commitment to any religion is not only intellectual suicide; it is positive unfaith because it closes the mind to any new vision of the world. Faith is, above all, openness - an act of trust in the unknown.
I am at a loss to understand why people hold Miss Austen's novels at so high a rate, which seem to me vulgar in tone, sterile in artistic invention, imprisoned in their wretched conventions of English society, without genius, wit, or knowledge of the world. Never was life so pinched and narrow. ... All that interests in any character [is this]: has he (or she) the money to marry with? ... Suicide is more respectable.
He must not merely cling to life, for then he will be a coward, and will not escape. He must not merely wait for death, for then he will be a suicide, and will not escape. He must seek his life in a spirit of furious indifference to it.
Nothing shall warp me from the belief that every man is a lover of truth. There is no pure lie, no pure malignity in nature. The entertainment of the proposition of depravity is the last profligacy and profanation. There is no skepticism, no atheism but that.

The weapon of suicide bombing is so desperate that you aren't even left with the possibility of taking revenge or punishing anyone; the terrorist is killed along with his victims, his blood mixing with theirs
Many statements about God are confidently made by theologians on grounds that today at least sound specious. Thomas Aquinas claimed to prove that God cannot make another God, or commit suicide, or make a man without a soul, or even make a triangle whose interior angles do not equal 180 degrees. But Bolyai and Lobachevsky were able to accomplish this last feat (on a curved surface) in the nineteenth century, and they were not even approximately gods.
