It has appeared in the second Essay of this volume, that there is not that broad and strong line of distinction between the wise man and the dull that has often been supposed. We are all of us by turns both the one and the other. Or, at least, the wisest man that ever existed spends a portion of his time in vacancy and dulness; and the man, whose faculties are seemingly the most obtuse, might, under proper management from the hour of his birth, barring those rare exceptions from the ordinary standard of mind which do not deserve to be taken into the account, have proved apt, adroit, intelligent and acute, in the walk for which his organisation especially fitted him(15). (15) See above, Essay 3. Many men without question, in a walk of the same duration as that above described between Temple-Bar and Hyde-Park-Corner, have passed their time in as much activity, and amidst as strong and various excitements, as those enumerated in the passage above quoted. But the lives of all men, the wise, and those whom by way of contrast we are accustomed to call the dull, are divided between animation and comparative vacancy; and many a man, who by the bursts of his genius has astonished the world, and commanded the veneration of successive ages, has spent a period of time equal to that occupied by a walk from Temple-Bar to Hyde-Park-Corner, in a state of mind as idle, and as little affording materials for recollection, as the dullest man that ever breathed the vital air. The two states of man which are here attempted to be distinguished, are, first, that in which reason is said to fill her throne, in which will prevails, and directs the powers of mind or of bodily action in one channel or another; and, secondly, that in which these faculties, tired of for ever exercising their prerogatives, or, being awakened as it were from sleep, and having not yet assumed them, abandon the helm, even as a mariner might be supposed to do, in a wide sea, and in a time when no disaster could be apprehended, and leave the vessel of the mind to drift, exactly as chance might direct. To describe this last state of mind I know not a better term that can be chosen, than that of reverie. It is of the nature of what I have seen denominated BROWN STUDY(16) a species of dozing and drowsiness, in which all men spend a portion of the waking part of every day of their lives. Every man must be conscious of passing minutes, perhaps hours of the day, particularly when engaged in exercise in the open air, in this species of neutrality and eviration. It is often not unpleasant at the time, and leaves no sinking of the spirits behind. It is probably of a salutary nature, and may be among the means, in a certain degree beneficial like sleep, by which the machine is restored, and the man comes forth from its discipline reinvigorated, and afresh capable of his active duties.
