Logical Atomism

Logical atomism is a philosophical belief that originated in the early 20th century with the development of analytic philosophy. Its principal exponents were the British philosopher Bertrand Russell, the early work of his Austrian-born pupil and colleague Ludwig Wittgenstein, and his German counterpart Rudolf Carnap.

The theory holds that the world consists of ultimate logical "facts" (or "atoms") that cannot be broken down any further. Having originally propounded this stance in his Tractatus Logico-Philosophicus, Wittgenstein rejected it in his later Philosophical Investigations.

The name for this kind of theory was coined in 1918 by Russell in response to what he called "logical holism"; i.e. the belief that the world operates in such a way that no part can be known without the whole being known first. This belief is commonly called monism, and in particular, Russell (and G.E. Moore) were reacting to the absolute idealism dominant then in Britain.

Famous quotes containing the word logical:

    The sensual and spiritual are linked together by a mysterious bond, sensed by our emotions, though hidden from our eyes. To this double nature of the visible and invisible world—to the profound longing for the latter, coupled with the feeling of the sweet necessity for the former, we owe all sound and logical systems of philosophy, truly based on the immutable principles of our nature, just as from the same source arise the most senseless enthusiasms.
    Karl Wilhelm Von Humboldt (1767–1835)
