Famous quotes containing the words natural and/or sciences:
“Death of the self in a long, tearless night,
All natural shapes blazing unnatural light.”
—Theodore Roethke (1908–1963)
“All cultural change reduces itself to a difference of categories. All revolutions, whether in the sciences or world history, occur merely because spirit has changed its categories in order to understand and examine what belongs to it, in order to possess and grasp itself in a truer, deeper, more intimate and unified manner.”
—Georg Wilhelm Friedrich Hegel (1770–1831)
