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:

    We all come from our own little planets. That’s why we’re all different. That’s what makes life interesting.
    Robert E. Sherwood (1896–1955)

    The symbol of perpetual youth, the grass-blade, like a long green ribbon, streams from the sod into the summer, checked indeed by the frost, but anon pushing on again, lifting its spear of last year’s hay with the fresh life below. It grows as steadily as the rill oozes out of the ground.... So our human life but dies down to its root, and still puts forth its green blade to eternity.
    Henry David Thoreau (1817–1862)

    What makes saintliness in my view, as distinguished from ordinary goodness, is a certain quality of magnanimity and greatness of soul that brings life within the circle of the heroic.
    Harriet Beecher Stowe (1811–1896)
