What is knowledge?

  • (noun): The psychological result of perception and learning and reasoning.
    Synonyms: cognition, noesis


Knowledge is a familiarity with someone or something, which can include facts, information, descriptions, or skills acquired through experience or education. It can refer to the theoretical or practical understanding of a subject. It can be implicit (as with practical skill or expertise) or explicit (as with the theoretical understanding of a subject); it can be more or less formal or systematic. In philosophy, the study of knowledge is called epistemology; the philosopher Plato famously defined knowledge as "justified true belief." However, no single agreed upon definition of knowledge exists, though there are numerous theories to explain it. The following quote from Bertrand Russell's "Theory of Knowledge" illustrates the difficulty in defining knowledge: "The question how knowledge should be defined is perhaps the most important and difficult of the three with which we shall deal. This may seem surprising: at first sight it might be thought that knowledge might be defined as belief which is in agreement with the facts. The trouble is that no one knows what a belief is, no one knows what a fact is, and no one knows what sort of agreement between them would make a belief true. Let us begin with belief."

Famous quotes containing the word knowledge:

    Whatever your hand finds to do, do with your might; for there is no work or thought or knowledge or wisdom in Sheol, to which you are going.
    Bible: Hebrew, Ecclesiastes 9:10.

    “... Knowledge he shall unwind
    Through victories of the mind,
    Till, clambering at the cradle-side,
    He dreams himself his mother’s pride,
    All knowledge lost in trance
    Of sweeter ignorance.”
    William Butler Yeats (1865–1939)

    The difference between the actual and the ideal force of man is happily figured in by the schoolmen, in saying, that the knowledge of man is an evening knowledge, vespertina cognitio, but that of God is a morning knowledge, matutina cognitio.
    Ralph Waldo Emerson (1803–1882)
