Fraenkel Set Theory

Famous quotes containing the words set and/or theory:

    “Thus all probable reasoning is nothing but a species of sensation. ‘Tis not solely in poetry and music, we must follow our taste and sentiment, but likewise in philosophy, When I am convinc’d of any principle, ‘tis only an idea which strikes more strongly upon me. When I give the preference to one set of arguments above another, I do nothing but decide from my feeling concerning the superiority of their influence.”
    —David Hume (1711–1776)

    “Won’t this whole instinct matter bear revision?
    Won’t almost any theory bear revision?
    To err is human, not to, animal.”
    —Robert Frost (1874–1963)
