Famous quotes containing the words orders, magnitude and/or energy:
“Our own physical body possesses a wisdom which we who inhabit the body lack. We give it orders which make no sense.”
—Henry Miller (1891–1980)
“We quaff the cup of life with eager haste without draining it, instead of which it only overflows the brim—objects press around us, filling the mind with their magnitude and with the throng of desires that wait upon them, so that we have no room for the thoughts of death.”
—William Hazlitt (1778–1830)
“Violence among young people ... is an aspect of their desire to create. They don’t know how to use their energy creatively so they do the opposite and destroy.”
—Anthony Burgess (b. 1917)
