The spurious prudence, making the senses final, is the god of sots and cowards, and is the subject of all comedy. It is nature’s joke, and therefore literature’s. The true prudence limits this sensualism by admitting the knowledge of an internal and real world. This recognition once made, the order of the world and the distribution of affairs and times, being studied with the co-perception of their subordinate place, will reward any degree of attention. For our existence, thus apparently attached in nature to the sun and the returning moon and the periods which they mark,—so susceptible to climate and to country, so alive to social good and evil, so fond of splendor and so tender to hunger and cold and debt,—reads all its primary lessons out of these books. Prudence does not go behind nature and ask whence it is. It takes the laws of the world whereby man’s being is conditioned, as they are, and keeps these laws that it may enjoy their proper good. It respects space and time, climate, want, sleep, the law of polarity, growth and death. There revolve, to give bound and period to his being on all sides, the sun and moon, the great formalists in the sky: here lies stubborn matter, and will not swerve from its chemical routine. Here is a planted globe, pierced and belted with natural laws and fenced and distributed externally with civil partitions and properties which impose new restraints on the young inhabitant. We eat of the bread which grows in the field. We live by the air which blows around us and we are poisoned by the air that is too cold or too hot, too dry or too wet. Time, which shows so vacant, indivisible and divine in its coming, is slit and peddled into trifles and tatters. A door is to be painted, a lock to be repaired. I want wood or oil, or meal or salt; the house smokes, or I have a headache; then the tax, and an affair to be transacted with a man without heart or brains, and the stinging recollection of an injurious or very awkward word,—these eat up the hours. Do what we can, summer will have its flies; if we walk in the woods we must feed mosquitos; if we go a-fishing we must expect a wet coat. Then climate is a great impediment to idle persons; we often resolve to give up the care of the weather, but still we regard the clouds and the rain.
