Famous quotes containing the words solid, state and/or physics:
“Constant revolutionizing of production ... distinguish the bourgeois epoch from all earlier ones. All fixed, fast-frozen relations, with their train of ancient and venerable prejudices are swept away, all new-formed ones become antiquated before they can ossify. All that is solid melts into air, all that is holy is profaned, and man is at last compelled to face with sober senses, his real conditions of life, and his relations with his kind.”
—Karl Marx (1818–1883)
“To one who habitually endeavors to contemplate the true state of things, the political state can hardly be said to have any existence whatever. It is unreal, incredible, and insignificant to him, and for him to endeavor to extract the truth from such lean material is like making sugar from linen rags, when sugar-cane may be had.”
—Henry David Thoreau (1817–1862)
“He who is conversant with the supernal powers will not worship these inferior deities of the wind, waves, tide, and sunshine. But we would not disparage the importance of such calculations as we have described. They are truths in physics because they are true in ethics.”
—Henry David Thoreau (1817–1862)
