The irony of science
The irony is that science has served only to show how small human knowledge is.
--
Humanity knows nothing at all. There is no intrinsic value in anything, and every action is futile, meaningless effort.
--
If we do have a food crisis it will not be caused by insufficiency of nature's productive power, but by the extravagance of human desire.
