“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)”

“... when someone sees a soul disturbed and unable to see something, he won't laugh mindlessly, but he'll take into consideration whether it has come from a brighter life and is dimmed through not having yet become accustomed to the dark or whether it has come from greater ignorance into greater light and is dazzled by the increased brillance.”

“A sensible man will remember that the eyes may be confused in two ways - by a change from light to darkness or from darkness to light; and he will recognise that the same thing happens to the soul.”

“The souls of all are from one and the same source but a soul which is unveiled shines out. Love and light come continually from such souls. We need no proof of it for it is living all else is dead in comparison.”

“Heathenism is a state of mind. You can take it that I’m referring to one who does not see his world. He has no mental light. He destroys almost unwittingly. He cannot feel any Gods presence in his life. He is the 21st century man.”

“Only one pair was still battling, apparently unaware of the new arrival. Harry saw Sirius duck Bellatrix's jet of red light: he was laughing at her.'Come on, you can do better than that!' he yelled, his voice echoing around the cavernous room.The second jet of light hit him squarely in the chest.The laughter had not quite died from his face, but his eyes widened in shock.”
