Famous quotes containing the words internal and/or entities:
“We have our difficulties, true; but we are a wiser and a tougher nation than we were in 1932. Never have there been six years of such far flung internal preparedness in all of history. And this has been done without any dictator’s power to command, without conscription of labor or confiscation of capital, without concentration camps and without a scratch on freedom of speech, freedom of the press or the rest of the Bill of Rights.”
—Franklin D. Roosevelt (1882–1945)
“Experimental work provides the strongest evidence for scientific realism. This is not because we test hypotheses about entities. It is because entities that in principle cannot be ‘observed’ are manipulated to produce a new phenomena
[sic] and to investigate other aspects of nature.”
—Ian Hacking (b. 1936)
