All art speaks in signs and symbols. No one can explain how it happens that the artist can waken to life in us the existence that he has seen and lives through. No artistic speech is the adequate expression of what it represents; its vital force comes from what is unspoken in it.
Albert SchweitzerNot one of us knows what effect his life produces, and what he gives to others; that is hidden from us and must remain so, though we are often allowed to see some little fraction of it, so that we may not lose courage.
Albert Schweitzer
