It isnot his possession of knowledge, of irrefutabletruth, that makes the man of science, but his persistent and recklessly critical quest for truth.

Man is the shuttle, to whose winding quest And passage through these looms God ordered motion, but ordained no rest.

-Vaughan, Henry
  Silex Scintillans,'Man'.

   Religion issomething which stands beyond, behind, and within the passing flux of immediate things; something which is real, and yet waiting to be realized; something which is a remote possibility, and yet the greatest of present facts; something that gives meaning to all that passes, and yet eludes apprehension; something whose possession is the final good, and yet is beyond all reach; something which is the ultimate ideal, and the hopeless quest.

-Whitehead, Alfred North
  Science and the ModernWorld.
