Famous quotes containing the words field and/or theory:

    “There is a call to life a little sterner,
    And braver for the earner, learner, yearner.
    Less criticism of the field and court
    And more preoccupation with the sport.”
    —Robert Frost (1874–1963)

    “Hygiene is the corruption of medicine by morality. It is impossible to find a hygienest who does not debase his theory of the healthful with a theory of the virtuous.... The true aim of medicine is not to make men virtuous; it is to safeguard and rescue them from the consequences of their vices.”
    —H.L. (Henry Lewis)
