Famous quotes containing the words sensitivity, syndrome and/or symptoms:
“Freedom of choice for women, at the expense of the caring, warmth, and sensitivity to others so often associated with them, may be empty. In the thrust to redefine male and female roles, women must not become men; nor can men be permitted the continual dehumanization of their roles.”
—Kathleen Weibel (b. 1945)
“[T]he syndrome known as life is too diffuse to admit of palliation. For every symptom that is eased, another is made worse. The horse leech’s daughter is a closed system. Her quantum of wantum cannot vary.”
—Samuel Beckett (1906–1989)
“Protest, evasion, merry distrust, and a delight in mockery are symptoms of health: everything unconditional belongs in pathology.”
—Friedrich Nietzsche (1844–1900)
