The Function Of Perfection

If thou shouldst say, "It is enough, I have reached perfection," all is lost.  For it is the function of perfection to make one know one's imperfection.

-- St. Augustine of Hippo (354 - 430), Christian theologian, rhetor, Doctor of the Catholic Church, saint, and philosopher, quoted by Aldous Huxley, in The Perennial Philosophy (1945)
