Efficient Causality

Famous quotes containing the words efficient and/or causality:

    An efficient and valuable man does what he can, whether the community pay him for it or not. The inefficient offer their inefficiency to the highest bidder, and are forever expecting to be put into office. One would suppose that they were rarely disappointed.
    Henry David Thoreau (1817–1862)

    Any important disease whose causality is murky, and for which treatment is ineffectual, tends to be awash in significance.
    Susan Sontag (b. 1933)
