William Kingdon Clifford — English Mathematician born on May 04, 1845, died on March 03, 1879

William Kingdon Clifford FRS was an English mathematician and philosopher. Building on the work of Hermann Grassmann, he introduced what is now termed geometric algebra, a special case of the Clifford algebra named in his honour. The operations of geometric algebra have the effect of mirroring, rotating, translating, and mapping the geometric objects that are being modelled to new positions. Clifford algebras in general and geometric algebra in particular, have been of ever increasing importance to mathematical physics,geometry, and computing. Clifford was the first to suggest that gravitation might be a manifestation of an underlying geometry. In his philosophical writings he coined the expression "mind-stuff"... (wikipedia)

If a belief is not realized immediately in open deeds, it is stored up for the guidance of the future.
The danger to society is not merely that it should believe wrong things, though that is great enough; but that it should become credulous, and lose the habit of testing things and inquiring into them; for then it must sink back into savagery.
This sense of power is the highest and best of pleasures when the belief on which it is founded is a true belief, and has been fairly earned by investigation.
It is wrong always, everywhere, and for anyone, to believe anything upon insufficient evidence.
The harm which is done by credulity in a man is not confined to the fostering of a credulous character in others, and consequent support of false beliefs.
