Famous quotes containing the words historical and/or years:

    “The analogy between the mind and a computer fails for many reasons. The brain is constructed by principles that assure diversity and degeneracy. Unlike a computer, it has no replicative memory. It is historical and value driven. It forms categories by internal criteria and by constraints acting at many scales, not by means of a syntactically constructed program. The world with which the brain interacts is not unequivocally made up of classical categories.”
    —Gerald M. Edelman (b. 1928)

    “I was born a mechanic, and made a barrel before I was ten years old. The cooper told my father, “Fanny made that barrel, and has done it quicker and better than any boy I have had after six months’ training.” My father looked at it and said, “What a pity that you were not born a boy so that you could be good for something. Run into the house, child, and go to knitting.””
    —Frances D. Gage (1808–1884)
