Famous quotes containing the words predicate and/or true:
“The predicate of truth-value of a proposition, therefore, is a mere fictive quality; its place is in an ideal world of science only, whereas actual science cannot make use of it. Actual science instead employs throughout the predicate of weight.”
—Hans Reichenbach (1891–1953)
“Whenever a true theory appears, it will be its own evidence. Its test is, that it will explain all phenomena.”
—Ralph Waldo Emerson (1803–1882)
