Robertson Davies said this quote

The eye sees only what the mind is prepared to comprehend.

~ Robertson Davies

I am quite a wise old bird, but I am no desert hermit who can only prophesy when his guts are knotted with hunger. I am deep in the old man’s puzzle, trying to link the wisdom of the body with the wisdom of the spirit until the two are one.

~ Robertson Davies

But the character of the music emphasized the tale as allegory--humorous, poignant, humane allegory--disclosing the metamorphosis of life itself, in which man moves from confident inexperience through the bitterness of experience, toward the rueful wisdom of self-knowledge.

~ Robertson Davies

Happiness is always a by-product. It is probably a matter of temperament, and for anything I know it may be glandular. But it is not something that can be demanded from life, and if you are not happy you had better stop worrying about it and see what treasures you can pluck from your own brand of unhappiness.

~ Robertson Davies
