Famous quotes containing the words secular and/or equilibrium:
“As high as mind stands above nature, so high does the state stand above physical life. Man must therefore venerate the state as a secular deity.... The march of God in the world, that is what the State is.”
—Georg Wilhelm Friedrich Hegel (1770–1831)
“There is a relation between the hours of our life and the centuries of time. As the air I breathe is drawn from the great repositories of nature, as the light on my book is yielded by a star a hundred millions of miles distant, as the poise of my body depends on the equilibrium of centrifugal and centripetal forces, so the hours should be instructed by the ages and the ages explained by the hours.”
—Ralph Waldo Emerson (1803–1882)
