“Let us not underrate the value of a fact; it will one day flower in a truth. It is astonishing how few facts of importance are added in a century to the natural history of any animal. The natural history of man himself is still being gradually written.”
—Henry David Thoreau (1817–1862)
“Your children are not here to fill the void left by marital dissatisfaction and disengagement. They are not to be utilized as a substitute for adult-adult intimacy. They are not in this world in order to satisfy a wife’s or a husband’s need for love, closeness or a sense of worth. A child’s task is to fully develop his/her emerging self. When we place our children in the position of satisfying our needs, we rob them of their childhood.”
—Aaron Hess (20th century)
“Paganism is infectious—more infectious than diphtheria or piety....”
—E.M. (Edward Morgan)
“A fiction about soft or easy deaths ... is part of the mythology of most diseases that are not considered shameful or demeaning.”
—Susan Sontag (b. 1933)
