Science is nothing but trained and organized common sense differing from the latter only as a veteran may differ from a raw recruit: and its methods differ from those of common sense only as far as the guardsman's cut and thrust differ from the manner in which a savage wields his club.
---Thomas Henry Huxley (1825-95)
Oh, and one on my earlier I-am-a-Robot philosophy:
The dispassionate intellect, the open mind, the unprejudiced observer, exist in an exact sense only in a sort of intellectualist folk-lore; states even approaching them cannot be reached without a moral and emotional effort most of us cannot or will not make.
---Wilfred Batten Lewis Trotter (1872-1939) English surgeon.
I like Dean Koontz too
"There are no physicists in the hottest parts of Hell, because the existence of a 'hottest part' implies a temperature difference, and any marginally competent physicist would immediately use this to run a heat engine and make some other part of Hell comfortably cool. This is obviously impossible."
-Professor Richard Davisson
