So far as hypotheses are concerned, let no one expect anything certain from astronomy, which cannot furnish it, lest he accept as the truth ideas conceived for another purpose, and depart from this study a greater fool than when he entered it.
For many parts of Nature can neither be invented with sufficient subtlety, nor demonstrated with sufficient perspicuity, nor accommodated unto use with sufficient dexterity, without the aid and intervening of the mathematics, of which sort are perspective, music, astronomy, cosmography, architecture, engineery, and divers others.
By: Francis Bacon
It would be as unthinkable to try to construct the Labour Party without Marx as it would to be to establish university faculties of astronomy,anthropology or psychology without permitting the study of Copernicus, Darwin or Freud, and still expect such faculties to be taken seriously
