The eye is continually influenced by what it cannot detect; nay, it is not going too far, to say that it is most influenced by what it detects least. Let the painter define, if he can, the variations of lines on which depend the change of expression in the human countenance.
John RuskinThere are, indeed, two forms of discontent: one laborious, the other indolent and complaining. We respect the man of laborious desire, but let us not suppose that his restlessness is peace, or his ambition meekness. It is because of the special connection of meekness with contentment that it is promised that the meek shall 'inherit the earth.' Neither covetous men, nor the grave, can inherit anything; they can but consume. Only contentment can possess.
John Ruskin
