Constructive Set Theory

Constructive set theory is an approach to mathematical constructivism following the program of axiomatic set theory. That is, it uses the usual first-order language of classical set theory, and although of course the logic is constructive, there is no explicit use of constructive types. Rather, there are just sets, thus it can look very much like classical mathematics done on the most common foundations, namely the Zermelo–Fraenkel axioms (ZFC).

Famous quotes containing the words constructive, set and/or theory:

    Friendship among nations, as among individuals, calls for constructive efforts to muster the forces of humanity in order that an atmosphere of close understanding and cooperation may be cultivated.
    Franklin D. Roosevelt (1882–1945)

    The love of truth, virtue, and the happiness of mankind are specious pretexts, but not the inward principles that set divines at work; else why should they affect to abuse human reason, to disparage natural religion, to traduce the philosophers as they universally do?
    George Berkeley (1685–1753)

    We have our little theory on all human and divine things. Poetry, the workings of genius itself, which, in all times, with one or another meaning, has been called Inspiration, and held to be mysterious and inscrutable, is no longer without its scientific exposition. The building of the lofty rhyme is like any other masonry or bricklaying: we have theories of its rise, height, decline and fall—which latter, it would seem, is now near, among all people.
    Thomas Carlyle (1795–1881)
