Actual Infinity

Actual infinity is the idea that numbers, or some other type of mathematical object, can form an actual, completed totality; namely, a set. Hence, in the philosophy of mathematics, the abstraction of actual infinity involves the acceptance of infinite entities, such as the set of all natural numbers or an infinite sequence of rational numbers, as given objects.

Famous quotes containing the words actual and/or infinity:

    What a perpetual disappointment is actual society, even of the virtuous and gifted! After interviews have been compassed with long foresight, we must be tormented presently by baffled blows, by sudden, unseasonable apathies, by epilepsies of wit and of animal spirits, in the heyday of friendship and thought. Our faculties do not play us true, and both parties are relieved by solitude.
    Ralph Waldo Emerson (1803–1882)

    As we begin to comprehend that the earth itself is a kind of manned spaceship hurtling through the infinity of space—it will seem increasingly absurd that we have not better organized the life of the human family.
    Hubert H. Humphrey (1911–1978)
