Famous quotes containing the words group and/or species:

    Laughing at someone else is an excellent way of learning how to laugh at oneself; and questioning what seem to be the absurd beliefs of another group is a good way of recognizing the potential absurdity of many of one’s own cherished beliefs.
    Gore Vidal (b. 1925)

    A man can go from being a lover to being a stranger in three moves flat ... but a woman under the guise of friendship will engage in acts of duplicity which come to light very much later. There are different species of self-justification.
    Anita Brookner (b. 1938)
