    Samuel Butler (1835–1902)

    The problems of the world, AIDS, cancer, nuclear war, pollution, are, finally, no more solvable than the problem of a tree which has borne fruit: the apples are overripe and they are falling—what can be done?... Nothing can be done, and nothing needs to be done. Something is being done—the organism is preparing to rest.
    David Mamet (b. 1947)

    fundamentally an organism has conscious mental states if and only if there is something that it is like to be that organism—something it is like for the organism.
    Thomas Nagel (b. 1938)
