Famous quotes containing the words test and/or substance:
“He who has never failed somewhere, that man can not be great. Failure is the true test of greatness. And if it be said, that continual success is a proof that a man wisely knows his powers,—it is only to be added, that, in that case, he knows them to be small.”
—Herman Melville (1819–1891)
“True, I talk of dreams,
Which are the children of an idle brain,
Begot of nothing but vain fantasy,
Which is as thin of substance as the air,
And more inconstant than the wind, who woos
Even now the frozen bosom of the north,
And being angered, puffs away from thence,
Turning his side to the dew-dropping south.”
—William Shakespeare (1564–1616)
