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:

    Sorrow is a kind of rust of the soul, which every new idea contributes in its passage to scour away. It is the putrefaction of stagnant life, and is remedied by exercise and motion.
    Samuel Johnson (1709–1784)

    The value of an idea has nothing whatsoever to do with the sincerity of the man who expresses it. Indeed, the probabilities are that the more insincere the man is, the more purely intellectual will the idea be, as in that case it will not be coloured by either his wants, his desires, or his prejudices.
    Oscar Wilde (1854–1900)

    The idea that you can merchandise candidates for high office like breakfast cereal—that you can gather votes like box tops—is, I think, the ultimate indignity to the democratic process.
    Adlai Stevenson (1900–1965)
