Famous quotes containing the words true and/or propositions:
“It is not true that there is dignity in all work. Some jobs are definitely better than others.... People who have good jobs are happy, rich, and well dressed. People who have bad jobs are unhappy, poor and use meat extenders. Those who seek dignity in the type of work that compels them to help hamburgers are certain to be disappointed.”
—Fran Lebowitz (b. 1950)
“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)
