Famous quotes containing the words check, clearing and/or system:
“The habit some writers indulge in of perpetual quotation is one it behoves lovers of good literature to protest against, for it is an insidious habit which in the end must cloud the stream of thought, or at least check spontaneity. If it be true that le style c’est l’homme, what is likely to happen if l’homme is for ever eking out his own personality with that of some other individual?”
—Dame Ethel Smyth (1858–1944)
“Though the words Canada East on the map stretch over many rivers and lakes and unexplored wildernesses, the actual Canada, which might be the colored portion of the map, is but a little clearing on the banks of the river, which one of those syllables would more than cover.”
—Henry David Thoreau (1817–1862)
“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.”
—Rudolf Carnap (1891–1970)
