The degree of one's emotions varies inversely with one's knowledge of the facts - the less you know the hotter you get.

Science can teach us, and I think our hearts can teach us, no longer to look around for imaginary supporters, no longer to invent allies in the sky, but rather to look to our own efforts here below to make the world a fit place to live.
