Famous quotes containing the word concerns:
“Art and science coincide insofar as both aim to improve the lives of men and women. The latter normally concerns itself with profit, the former with pleasure. In the coming age, art will fashion our entertainment out of new means of productivity in ways that will simultaneously enhance our profit and maximize our pleasure.”
—Bertolt Brecht (1898–1956)
“Science asks no questions about the ontological pedigree or a priori character of a theory, but is content to judge it by its performance; and it is thus that a knowledge of nature, having all the certainty which the senses are competent to inspire, has been attained—a knowledge which maintains a strict neutrality toward all philosophical systems and concerns itself not with the genesis or a priori grounds of ideas.”
—Chauncey Wright (1830–1875)
“Universal empire is the prerogative of a writer. His concerns are with all mankind, and though he cannot command their obedience, he can assign them their duty. The Republic of Letters is more ancient than monarchy, and of far higher character in the world than the vassal court of Britain.”
—Thomas Paine (1737–1809)
