True art and true science possess two unmistakable marks: the first, an inward mark, which is this, that the servitor of art and science will fulfil his vocation, not for profit but with self- sacrifice; and the second, an external sign, his productions will be intelligible to all the people whose welfare he has in view.
Leo TolstoyThe vegetarian movement ought to fill with gladness the souls of those who have at heart the realization of God's kingdom upon earth, not because vegetarianism itself is such an important step towards the realization of this kingdom (all real steps are equally important or unimportant), but because it serves as a criterion by which we know that the pursuit of moral perfection on the part of man is genuine and sincere.
Leo TolstoyIn spite the mountains of books written about art, no precise definition of art has been constructed. And the reason for this is that the conception of art has been based on the conception of beauty.
