Science is organized common sense where many a beautiful theory was killed by an ugly fact. – Thomas Huxley

I do not say think as I think, but think in my way. Fear no shadows, least of all in that great spectre of personal unhappiness which binds half the world to orthodoxy. – Thomas Huxley
The only medicine for suffering, crime, and all other woes of mankind, is wisdom. Teach a man to read and write, and you have put into his hands the great keys of the wisdom box. But it is quite another thing to open the box. – Thomas Huxley
