Man is a small kosmos.

Democritus, (per Philip Wheelwright, The PreSocratics)

I always fare the best with my innocuousness, which is up to 20 percent conscious. This is easily attained when you're indifferent to the feelings of your dear fellow humans—but you are never as indifferent to them as they deserve.

Albert Einstein as quoted by Lee Smolin in "The Other Einstein" on how he keeps his cool, in the New York Review of Books, June 14, 2007.
