Famous quotes containing the words optical and/or purity:
“People who have realized that this is a dream imagine that it is easy to wake up, and are angry with those who continue sleeping, not considering that the whole world that environs them does not permit them to wake. Life proceeds as a series of optical illusions, artificial needs and imaginary sensations.”
—Alexander Herzen (1812–1870)
“Do not be discouraged, if in a thousand instances you find your kindness rejected and wronged, your good evil-spoken of, and the hand you extend for the relief of others, cast insultingly away; the benevolence which cannot outlive these trials of its purity and strength, is not like the self-sacrifice of him, who went about doing good.”
—C., U.S. women’s magazine contributor. American Ladies Magazine, pp. 331-4 (July 1828)
