Famous quotes containing the words potential and/or problems:
“Silence is as full of potential wisdom and wit as the unhewn marble of great sculpture. The silent bear no witness against themselves.”
—Aldous Huxley (1894–1963)
“There are nowadays professors of philosophy, but not philosophers. Yet it is admirable to profess because it was once admirable to live. To be a philosopher is not merely to have subtle thoughts, nor even to found a school, but so to love wisdom as to live according to its dictates, a life of simplicity, independence, magnanimity, and trust. It is to solve some of the problems of life, not only theoretically, but practically.”
—Henry David Thoreau (1817–1862)
