Famous quotes containing the words outer and/or circle:

    “The heartless and enormous Outer Black ...”
    —Robert Frost (1874–1963)

    “That three times five is equal to the half of thirty, expresses a relation between these numbers. Propositions of this kind are discoverable by the mere operation of thought, without dependence on what is any where existent in the universe. Though there never were a circle or triangle in nature, the truths, demonstrated by Euclid, would for ever retain their certainty and evidence.”
    —David Hume (1711–1776)
