Famous quotes containing the word uncertainty:
“Now, since our condition accommodates things to itself, and transforms them according to itself, we no longer know things in their reality; for nothing comes to us that is not altered and falsified by our Senses. When the compass, the square, and the rule are untrue, all the calculations drawn from them, all the buildings erected by their measure, are of necessity also defective and out of plumb. The uncertainty of our senses renders uncertain everything that they produce.”
—Michel de Montaigne (1533–1592)
“What a chimera then is man. What a novelty! What a monster, what a chaos, what a contradiction, what a prodigy. Judge of all things, imbecile worm of the earth; depositary of truth, a sink of uncertainty and error: the pride and refuse of the universe.”
—Blaise Pascal (1623–1662)
“It was your severed image that grew sweeter,
That floated, wing-stiff, focused in the sun
Along uncertainty and gales of shame
Blown out before I slept. Now you are one
I dare not think alive: only a name
That chimes occasionally, as a belief
Long since embedded in the static past.”
—Philip Larkin (1922–1986)
