Famous quotes containing the words express and/or propositions:
“Every family should extend First Amendment rights to all its members, but this freedom is particularly essential for our kids. Children must be able to say what they think, openly express their feelings, and ask for what they want and need if they are ever able to develop an integrated sense of self. They must be able to think their own thoughts, even if they differ from ours. They need to have the opportunity to ask us questions when they don’t understand what we mean.”
—Stephanie Martson (20th century)
“It has often been argued that absolute scepticism is self-contradictory; but this is a mistake: and even if it were not so, it would be no argument against the absolute sceptic, inasmuch as he does not admit that no contradictory propositions are true. Indeed, it would be impossible to move such a man, for his scepticism consists in considering every argument and never deciding upon its validity; he would, therefore, act in this way in reference to the arguments brought against him.”
—Charles Sanders Peirce (1839–1914)
