Famous quotes containing the words examples of, examples and/or collective:

    There are many examples of women that have excelled in learning, and even in war, but this is no reason we should bring ‘em all up to Latin and Greek or else military discipline, instead of needle-work and housewifry.
    Bernard Mandeville (1670–1733)

    In the examples that I here bring in of what I have [read], heard, done or said, I have refrained from daring to alter even the smallest and most indifferent circumstances. My conscience falsifies not an iota; for my knowledge I cannot answer.
    Michel de Montaigne (1533–1592)

    Anyone who is kind to man knows the fragmentariness of most men, and wants to arrange a society of power in which men fall naturally into a collective wholeness, since they cannot have an individual wholeness. In this collective wholeness they will be fulfilled. But if they make efforts at individual fulfilment, they must fail for they are by nature fragmentary.
    —D.H. (David Herbert)
