Observe that the least things and effects in Nature are not without charm and beauty, as the little cracks in the crust of a loaf, though not intended by the baker, are agreeable and invite the appetite. Thus figs, when they are ripest, open and gape; and olives, when they are near decaying, are peculiarly attractive. The bending of an ear of corn, the frown of a lion, the foam of a boar, and many other like things, if you take them singly, are far from beautiful; but seen in their natural relations are characteristic and effective. So if a man have but inclination and thought to examine the product of the universe, he will find that the most unpromising appearances have their own appropriate charm. Do not spend your thoughts upon other people, nor pry into the talk, fancies and projects of another, nor guess at what he is about, or why he is doing it. Think upon nothing but what you could willingly tell about, so that if your soul were laid open there would appear nothing but what was sincere, good-natured, and public-spirited. A man thus qualified is a sort of priest and minister of the gods, and makes a right use of the divinity within him. Be cheerful; depend not at all on foreign supports, nor beg your happiness of another; don't throw away your legs to stand upon crutches. If, in the whole compass of human life, you find anything preferable to justice and truth, temperance and fortitude, or to a mind self-satisfied with its own rational conduct and entirely resigned to fate, then turn to it as to your supreme happiness. But if there be nothing more valuable than the divinity within you, if all things are trifles in comparison with this, then don't divide your allegiance. Let your choice run all one way, and be resolute for that which is best. As for other speculations, throw them once for all out of your hand. _BOOK IV_ It is the custom of people to go to unfrequented places and to the seashore and to the hills for retirement; and you yourself have often wished this solitude. But, after all, this is only a vulgar fancy, for it is in your power to withdraw into yourself whenever you have a mind to it. One's own heart is a place the most free from crowd and noise in the world if only one's thoughts are serene and the mind well ordered. Make, therefore, frequent use of this retirement, therein to refresh your virtue. And to this end be always provided with a few short, uncontested notions, to keep your understanding true. Do not forget to retire to this solitude of yours; let there be no straining or struggling in the matter, but move at ease. If understanding be common to us all, then reason, its cause, must be common, too. And so also must the reason which governs conduct by commands and prohibitions be common to us all. Mankind is therefore under one common law, and so are fellow-citizens; and the whole world is but one commonwealth, for there is no other society in which mankind can be incorporated.
