Controlled Substance

Famous quotes containing the words controlled and/or substance:

“Science is a system of statements based on direct experience, and controlled by experimental verification. Verification in science is not, however, of single statements but of the entire system or a sub-system of such statements.”

“Strong be thy wallis that about the standis;
Wise be the people that within the dwellis;
Fresh is thy ryver with his lusty strandis;
Blith be thy chirches, wele sownyng be thy bellis;
Riche be thy merchauntis in substance that excellis
Fair be thy wives, right lovesom, white and small;
Clere be thy virgyns, lusty under kellis:
London, thou art the flour of Cities all.”
—William Dunbar (c. 1465–c. 1530)
