Famous quotes containing the word apt:

    You ask if there is no doctrine of sorrow in my philosophy. Of acute sorrow I suppose that I know comparatively little. My saddest and most genuine sorrows are apt to be but transient regrets. The place of sorrow is supplied, perchance, by a certain hard and proportionately barren indifference. I am of kin to the sod, and partake of its dull patience,—in winter expecting the sun of spring.
    Henry David Thoreau (1817–1862)
