Life

Life (cf. biota) is a characteristic that distinguishes objects that have signaling and self-sustaining processes from those that do not, either because such functions have ceased (death), or else because they lack such functions and are classified as inanimate. Biology is the science concerned with the study of life.

Famous quotes containing the word life:

    Everything one does in life, even love, occurs in an express train racing toward death. To smoke opium is to get out of the train while it is still moving. It is to concern oneself with something other than life or death.
    Jean Cocteau (1889–1963)

    There is no way to penetrate the surface of life but by attacking it earnestly at a particular point.
    Charles Horton Cooley (1864–1929)

    If I had my life over again I should form the habit of nightly composing myself to thoughts of death. I would practise, as it were, the remembrance of death. There is no other practice which so intensifies life. Death, when it approaches, ought not to take one by surprise. It should be part of the full expectancy of life. Without an ever- present sense of death life is insipid. You might as well live on the whites of eggs.
    Muriel Spark (b. 1918)
