Anything that is beautiful is beautiful just as it is. Praise forms no part of its beauty, since praise makes things neither better nor worse. This applies even more to what it commonly called beautiful: natural objects, for example, or works of art. True beauty has no need of anything beyond itself.
Marcus AureliusAlways follow these two rules: first, act only on what your reasoning mind proposes for the good of humanity, and second, change your opinion if someone shows you it's wrong. This change of mind must proceed only from the conviction that it's both correct and for the common good, but not because it will give you pleasure and make you popular.
Marcus AureliusEnough of this wretched life and murmuring and apish tricks. Why art thou disturbed? What is there new in this? What unsettles thee? Is it the form of the thing? Look at it. Or is it the matter? Look at it. But besides these there is nothing. Towards the gods, then, now become at last more simple and better. It is the same whether we examine these things for a hundred years or three.
Marcus Aurelius
