Famous quotes containing the word purpose:
“Whoever considers morality the main objective of human existence, seems to me like a person who defines the purpose of a clock as not going wrong. The first objective for a clock, is, however, that it does run; not going wrong is an additional regulative function. If not a watch’s greatest accomplishment were not going wrong, unwound watches might be the best.”
—Franz Grillparzer (1791–1872)
“The chief want, in every State that I have been into, was a high and earnest purpose in its inhabitants. This alone draws out “the great resources” of Nature, and at last taxes her beyond her resources; for man naturally dies out of her.”
—Henry David Thoreau (1817–1862)
“To found a great empire for the sole purpose of raising up a people of customers, may at first sight appear a project fit only for a nation of shopkeepers. It is, however, a project altogether unfit for a nation of shopkeepers, but extremely fit for a nation that is governed by shopkeepers.”
—Adam Smith (1723–1790)
