“The world will never be long without some good reason to hate the unhappy; their real faults are immediately detected, and if those are not sufficient to sink them into infamy, an additional weight of calumny will be superadded.”
—Samuel Johnson (1709–1784)
“For such an advanced civilization as ours to be without images that are adequate to it is as serious a defect as being without memory.”
