They deem him their worst enemy who tells them the truth. -Plato, philosopher (427-347 BCE) - Plato

....I am inclined to think that these muscles and bones of mine would have gone off long ago to Megara or Boeotia — by the dog they would, if they had been moved only by their own idea of what was best.

(tr Jowett)

"Any one who has common sense will remember that the bewilderments of the eyes are of two kinds, and arise from two causes, either from coming out of the light or from going into the light, which is true of the mind's eye, quite as much as of the bodily eye; and he who remembers this when he sees any one whose vision is perplexed and weak, will not be too ready to laugh; he will first ask whether that soul of man has come out of the brighter life, and is unable to see because unaccustomed to the dark, or having turned from dakness to the day is dazzled by excess of light. And he will count the one happy in his condition and state of being, and he will pity the other; or, if he have a mind to laugh at the soul which comes from below into the light, there will be more reason in this than in the laugh which greets him who returns from above out of the light into the den. (Included in the introduction to "Flowers for Algernon" by Daniel Keyes)"

First, I must distinguish between that which always is and never becomes and which is apprehended by reason and reflection, and that which always becomes and never is and is conceived by opinion with the help of sense.
