Famous quotes containing the words empirical and/or tests:
“To develop an empiricist account of science is to depict it as involving a search for truth only about the empirical world, about what is actual and observable.... It must involve throughout a resolute rejection of the demand for an explanation of the regularities in the observable course of nature, by means of truths concerning a reality beyond what is actual and observable, as a demand which plays no role in the scientific enterprise.”
—Bas Van Fraassen (b. 1941)
“The secret of a leader lies in the tests he has faced over the whole course of his life and the habit of action he develops in meeting those tests.”
—Gail Sheehy (b. 1937)
