When we use harsh words, biting comments, and a sarcastic tone of voice, we plant the seeds of self-doubt in their developing minds.... Children who receive a steady diet of these types of messages end up feeling powerless, inadequate, and unimportant. They start to believe that they are bad, and that they can never do enough.”
—Stephanie Martson (20th century)
“Like ultraviolet rays memory shows to each man in the book of life a script that invisibly and prophetically glosses the text.”
—Walter Benjamin (1892–1940)
“With his head over his shoulder turned,
He seemed to find his way without his eyes,
For out o’ doors he went without their help,
And to the last bended their light on me.”
