Meditations, Book III, Section 2

One can find beauty in unexpected places. I would argue that you can even find beauty in litter (which isn't to say that litter is good for the environment). Some litter has the most astonishing colors and reflective, glossy surfaces. But the beauty of litter is only available to those who suspend their judgment. 

Meditations, Book III, Section 2: 

This also thou must observe, that whatsoever it is that naturally doth happen to things natural, hath somewhat in itself that is pleasing and delightful: as a great loaf when it is baked, some parts of it cleave as it were, and part asunder, and make the crust of it rugged and unequal, and yet those parts of it, though in some sort it be against the art and intention of baking itself, that they are thus cleft and parted, which should have been and were first made all even and uniform, they become it well nevertheless, and have a certain peculiar property, to stir the appetite. So figs are accounted fairest and ripest then, when they begin to shrink, and wither as it were. So ripe olives, when they are next to putrefaction, then are they in their proper beauty. The hanging down of grapes—the brow of a lion, the froth of a foaming wild boar, and many other like things, though by themselves considered, they are far from any beauty, yet because they happen naturally, they both are comely, and delightful; so that if a man shall with a profound mind and apprehension, consider all things in the world, even among all those things which are but mere accessories and natural appendices as it were, there will scarce appear anything unto him, wherein he will not find matter of pleasure and delight. So will he behold with as much pleasure the true rictus of wild beasts, as those which by skilful painters and other artificers are imitated. So will he be able to perceive the proper ripeness and beauty of old age, whether in man or woman: and whatsoever else it is that is beautiful and alluring in whatsoever is, with chaste and continent eyes he will soon find out and discern. Those and many other things will he discern, not credible unto every one, but unto them only who are truly and familiarly acquainted, both with nature itself, and all natural things.
