Famous quotes containing the word history:

    Those who weep for the happy periods which they encounter in history acknowledge what they want; not the alleviation but the silencing of misery.
    Albert Camus (1913–1960)

    Philosophy of science without history of science is empty; history of science without philosophy of science is blind.
    Imre Lakatos (1922–1974)

    In the history of the human mind, these glowing and ruddy fables precede the noonday thoughts of men, as Aurora the sun’s rays. The matutine intellect of the poet, keeping in advance of the glare of philosophy, always dwells in this auroral atmosphere.
    Henry David Thoreau (1817–1862)
