Famous quotes containing the word deficiency:
“If a man is a good lawyer, a good physician, a good engineer ... he may be a fool in every other capacity. But no deficiency or mistake of judgment is forgiven to a woman ... and should she fail anywhere, if she has any scientific attainment, or artistic faculty, instead of standing her interest as an excuse, it is censured as an aggravation and offence.”
—E.P.P., U.S. women’s magazine contributor. The Una, p. 28 ( February 1855)

“Shakespeare’s fault is not the greatest into which a poet may fall. It merely indicates a deficiency of taste.”
