Famous quotes containing the word fitness:
“... it is use, and use alone, which leads one of us, tolerably trained to recognize any criterion of grace or any sense of the fitness of things, to tolerate ... the styles of dress to which we are more or less conforming every day of our lives. Fifty years hence they will seem to us as uncultivated as the nose-rings of the Hottentot seem today.”
—Elizabeth Stuart Phelps (1844–1911)
“Parentage is a very important profession; but no test of fitness for it is ever imposed in the interest of children.”
—George Bernard Shaw (1856–1950)
“Critics generally come to be critics not by reason of their fitness for this, but of their unfitness for anything else. Books should be tried by a judge and jury as though they were a crime, and counsel should be heard on both sides.”
—Samuel Butler (1835–1902)
