When, however, we turn to “zeal” or “energy” or “go,” we do seem to be dealing with a simpler and more transmissible thing. Let us assume that in this matter there is a wide range of difference that may be arranged in a direct and simple scale in quantitative relation to the gross output of action of different human beings. One passes from the incessant employment of such a being as Gladstone at the one extreme, a loquacious torrent of interests and achievements, to the extreme of phlegmatic lethargy on the other. Call the former a high energetic and the latter low. Quite possibly it might be found that we could breed “high energetics.” But before we did so we should have to consider very gravely that the “go” and “energy” of a man have no ascertainable relation to many other extremely important considerations. Your energetic person may be moral or immoral, an unqualified egotist or as public spirited as an ant, sane, or a raving lunatic. Your phlegmatic person may ripen resolves and bring out truths, with the incomparable clearness of a long-exposed, slowly developed, slowly printed photograph. A man who would exchange the slow gigantic toil of that sluggish and deliberate person, Charles Darwin, for the tumultuous inconsequence and (as some people think it) the net mischief of a Gladstone, would no doubt be prepared to substitute a Catherine-wheel in active eruption for the watch of less adventurous men. But before we could induce the community as a whole to make a similar exchange, he would have to carry on a prolonged and vigorous propaganda. For my own part--and I write as an ignorant man in a realm where ignorance prevails--I am inclined to doubt the simplicity and homogeneity even of this quality of “energy” or “go.” A person without restraint, without intellectual conscience, without critical faculty, may write and jabber and go to and fro and be here and there, simply because every impulse is obeyed so soon as it arises. Another person may be built upon an altogether larger scale of energy, but may be deliberate, concentrated, and fastidious, bent rather upon truth and permanence than upon any immediate quantitative result, and may appear to any one but an extremely penetrating critic, as inferior in energy to the former. So far as our knowledge goes at present, what is popularly known as “energy” or “go” is just as likely to be a certain net preponderance of a varied miscellany of impulsive qualities over a varied miscellany of restraints and inhibitions, as it is to prove a simple indivisible quality transmissible intact. We are so profoundly ignorant in these matters, so far from anything worthy of the name of science, that one view is just as permissible and just as untrustworthy as the other.
