—Václav Havel (b. 1936)
“Though a censure lies against those who are poor and proud, yet is Pride sooner to be forgiven in a poor person than in a rich one; since in the latter it is insult and arrogance; in the former, it may be a defense against temptations to dishonesty; and, if manifested on proper occasions, may indicate a natural bravery of mind, which the frowns of fortune cannot depress.”
—Samuel Richardson (1689–1761)
