Natural Sciences

Famous quotes containing the words natural and/or sciences:

“The enemy is like a woman, weak in face of opposition, but correspondingly strong when not opposed. In a quarrel with a man, it is natural for a woman to lose heart and run away when he faces up to her; on the other hand, if the man begins to be afraid and to give ground, her rage, vindictiveness and fury overflow and know no limit.”
—St. Ignatius Of Loyola (1491–1556)

“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)
