Quotations for Today
	Science can never be a closed book. It is like a tree, ever growing, ever reaching new heights. Occasionally the lower branches, no longer giving nourishment to the tree, slough off. We should not be ashamed to change our methods; rather we should be ashamed never to do so. - Charles V. Chapin, American physician, public health officer and epidemiologist (born 17 Jan 1856).
	It seems to me, that if statesmen had a little more arithmetic, or were accustomed to calculation, wars would be much less frequent. - Benjamin Franklin, American statesman, scientist, inventor, diplomat, author, printer and publisher (born 17 Jan 1706).
	We do not draw conclusions with our eyes, but with our reasoning powers, and if the whole of the rest of living nature proclaims with one accord from all sides the evolution of the world of organisms, we cannot assume that the process stopped short of Man. But it follows also that the factors which brought about the development of Man from his Simian ancestry must be the same as those which have brought about the whole of evolution. - August Weismann, German biologist (born 17 Jan 1834).
