Famous quotes containing the words positive and/or test:
“Regna regnis lupi, The State is a wolf unto the State. It is not a pessimistic lamentation like the old homo homini lupus [Man is a wolf to Man], but a positive creed and political ideal.”
—Johan Huizinga (1872–1945)
“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)
