Beliefnet (Inspiration. Spirituality. Faith) introduces its 10 Uplifting Quotes for a Depressed Heart as follows:
What is it about a short quotation that carries so much power? Anyone who has ever been moved by "I have a dream" or "I think, therefore I am" knows that a single, simple quote can change a day, a life, a world.I think therefore I am?
