The belief that science destroys culture is sometimes supported by historical statements that the arts have flourished only when the sciences have been neglected. This thesis is... directly contrary to history... [I]n the great age of Greece, art and science penetrate one another more closely than in any modern age. ...The example of these men in science as much as in art set the modern world afire in the Renaissance. And the type and symbol of Renaissance man... remains Leonardo da Vinci, painter, sculptor, mathematician, and engineer. No man has shown more strikingly the universality and the unity of the intellect.
