Famous quotes containing the words defense and/or system:
“Though a censure lies against those who are poor and proud, yet is Pride sooner to be forgiven in a poor person than in a rich one; since in the latter it is insult and arrogance; in the former, it may be a defense against temptations to dishonesty; and, if manifested on proper occasions, may indicate a natural bravery of mind, which the frowns of fortune cannot depress.”
—Samuel Richardson (1689–1761)
“He is not a true man of science who does not bring some sympathy to his studies, and expect to learn something by behavior as well as by application. It is childish to rest in the discovery of mere coincidences, or of partial and extraneous laws. The study of geometry is a petty and idle exercise of the mind, if it is applied to no larger system than the starry one.”
—Henry David Thoreau (1817–1862)
