Famous quotes containing the words instability and/or crow:
“The difference between tragedy and comedy is the difference between experience and intuition. In the experience we strive against every condition of our animal life: against death, against the frustration of ambition, against the instability of human love. In the intuition we trust the arduous eccentricities were born to, and see the oddness of a creature who has never got acclimatized to being created.”
—Christopher Fry (b. 1907)

That the snow grows whiter
