Famous quotes containing the words logical and/or argument:
“It is possible—indeed possible even according to the old conception of logic—to give in advance a description of all ‘true’ logical propositions. Hence there can never be surprises in logic.”
—Ludwig Wittgenstein (1889–1951)
“Because a person is born the subject of a given state, you deny the sovereignty of the people? How about the child of Cuban slaves who is born a slave, is that an argument for slavery? The one is a fact as well as the other. Why then, if you use legal arguments in the one case, you don’t in the other?”
—Franz Grillparzer (1791–1872)
