Famous quotes containing the words natural and/or sciences:
“The urgent consideration of the public safety may undoubtedly authorise the violation of every positive law. How far that or any other consideration may operate to dissolve the natural obligations of humanity and justice, is a doctrine of which I still desire to remain ignorant.”
—Edward Gibbon (1737–1794)
“These modern ingenious sciences and arts do not affect me as those more venerable arts of hunting and fishing, and even of husbandry in its primitive and simple form; as ancient and honorable trades as the sun and moon and winds pursue, coeval with the faculties of man, and invented when these were invented. We do not know their John Gutenberg, or Richard Arkwright, though the poets would fain make them to have been gradually learned and taught.”
—Henry David Thoreau (1817–1862)
