Epigraph

If a little knowledge is dangerous, where is the man who has so much to be out of danger!

T. H. Huxley, 1825 1895 from Elementary Instruction in Physiology published in 1877

It is the tragedy of the world that no one knows what he doesn't know and the less a man knows, the more sure he is that he knows everything

Joyce Cary, British author 1888 1957

Nothing in the world can take the place of persistence. Talent will not; nothing is more common than unsuccessful men with talent. Genius will not; unrewarded genius is almost a proverb. Education will not; the world is full of educated derelicts. Persistence and determination alone are omnipotent.

Calvin Coolidge 1872 1933, Vice President 1921 1923, President 1923 1929
