An idea is a concept or mental impression. Very often, ideas are construed as representational images; i.e. images of some object. In other contexts, ideas are taken to be concepts, although abstract concepts do not necessarily appear as images. Many philosophers consider ideas to be a fundamental ontological category of being. The capacity to create and understand the meaning of ideas is considered to be an essential and defining feature of human beings. In a popular sense, an idea arises in a reflex, spontaneous manner, even without thinking or serious reflection, for example, when we talk about the idea of a person or a place.

Famous quotes containing the word idea:

    During our twenties...we act toward the new adulthood the way sociologists tell us new waves of immigrants acted on becoming Americans: we adopt the host culture’s values in an exaggerated and rigid fashion until we can rethink them and make them our own. Our idea of what adults are and what we’re supposed to be is composed of outdated childhood concepts brought forward.
    Roger Gould (20th century)

    The idea that leisure is of value in itself is only conditionally true.... The average man simply spends his leisure as a dog spends it. His recreations are all puerile, and the time supposed to benefit him really only stupefies him.
    —H.L. (Henry Lewis)

    Well may Mr. [David] Garrick be so celebrated, so universally admired—I had not any idea of so great a performer. Such ease! such vivacity in his manner! such grace in his motions! such fire and meaning in his eyes!—I could hardly believe he had studied a written part, for every word seemed uttered from the impulse of the moment. ... his voice—so clear, so melodious, yet so wonderfully various in its tones!
    Frances Burney (1752–1840)
