[Raphael's] great superiority is due to the instinctive sense which, in him, seems to desire to shatter form. Form is, in his figures, what it is in ourselves, an interpreter for the communication of ideas and sensations, an exhaustless source of poetic inspiration. Every figure is a world in itself, a portrait of which the original appeared in a sublime vision, in a flood of light, pointed to by an inward voice, laid bare by a divine finger which showed what the sources of expression had been in the whole past life of the subject.
If you remember nothing else, remember this: Inspiration from outside one's self is like the heat in an oven. It makes passable Bath buns. But inspiration from within is like a volcano: It changes the face of the world.
The realization that we are all basically the same human beings who seek happiness and try to avoid suffering is very helpful in developing a sense of brotherhood and sisterhood; a warm feeling of love and compassion for others.
