Speculative ability depends on vigorous thinking--practical ability on vigorous acting; and the two qualities are usually found combined in very unequal proportions. The speculative man is prone to indecision: he sees all the sides of a question, and his action becomes suspended in nicely weighing the pros and cons, which are often found pretty nearly to balance each other; whereas the practical man overleaps logical preliminaries, arrives at certain definite convictions, and proceeds forthwith to carry his policy into action. (23)Yet there have been many great men of science who have proved efficient men of business. We do not learn that Sir Isaac Newton made a worse Master of the Mint because he was the greatest of philosophers. Nor were there any complaints as to the efficiency of Sir John Herschel, who held the same office. The brothers Humboldt were alike capable men in all that they undertook--whether it was literature, philosophy, mining, philology, diplomacy, or statesmanship.
Niebuhr, the historian, was distinguished for his energy and success as a man of business. He proved so efficient as secretary and accountant to the African consulate, to which he had been appointed by the Danish Government, that he was afterwards selected as one of the commissioners to manage the national finances; and he quitted that office to undertake the joint directorship of a bank at Berlin. It was in the midst of his business occupations that he found time to study Roman history, to master the Arabic, Russian, and other Sclavonic languages, and to build up the great reputation as an author by which he is now chiefly remembered.
Having regard to the views professed by the First Napoleon as to men of science, it was to have been expected that he would endeavour to strengthen his administration by calling them to his aid. Some of his appointments proved failures, while others were completely successful. Thus Laplace was made Minister of the Interior; but he had no sooner been appointed than it was seen that a mistake had been made. Napoleon afterwards said of him, that "Laplace looked at no question in its true point of view. He was always searching after subtleties; all his ideas were problems, and he carried the spirit of the infinitesimal calculus into the management of business." But Laplace's habits had been formed in the study, and he was too old to adapt them to the purposes of practical life.
With Darn it was different. But Darn had the advantage of some practical training in business, having served as an intendant of the army in Switzerland under Massena, during which he also distinguished himself as an author. When Napoleon proposed to appoint him a councillor of state and intendant of the Imperial Household, Darn hesitated to accept the office. "I have passed the greater part of my life," he said, "among books, and have not had time to learn the functions of a courtier." "Of courtiers,"replied Napoleon, "I have plenty about me; they will never fail.
But I want a minister, at once enlightened, firm, and vigilant;and it is for these qualities that I have selected you." Darn complied with the Emperor's wishes, and eventually became his Prime Minister, proving thoroughly efficient in that capacity, and remaining the same modest, honourable, and disinterested man that he had ever been through life.
Men of trained working faculty so contract the habit of labour that idleness becomes intolerable to them; and when driven by circumstances from their own special line of occupation, they find refuge in other pursuits. The diligent man is quick to find employment for his leisure; and he is able to make leisure when the idle man finds none. "He hath no leisure," says George Herbert, "who useth it not." "The most active or busy man that hath been or can be," says Bacon, "hath, no question, many vacant times of leisure, while he expecteth the tides and returns of business, except he be either tedious and of no despatch, or lightly and unworthily ambitious to meddle with things that may be better done by others." Thus many great things have been done during such "vacant times of leisure," by men to whom industry had become a second nature, and who found it easier to work than to be idle.
Even hobbies are useful as educators of the working faculty.
Hobbies evoke industry of a certain kind, and at least provide agreeable occupation. Not such hobbies as that of Domitian, who occupied himself in catching flies. The hobbies of the King of Macedon who made lanthorns, and of the King of France who made locks, were of a more respectable order. Even a routine mechanical employment is felt to be a relief by minds acting under high-pressure: it is an intermission of labour--a rest--a relaxation, the pleasure consisting in the work itself rather than in the result.
But the best of hobbies are intellectual ones. Thus men of active mind retire from their daily business to find recreation in other pursuits--some in science, some in art, and the greater number in literature. Such recreations are among the best preservatives against selfishness and vulgar worldliness. We believe it was Lord Brougham who said, "Blessed is the man that hath a hobby!"and in the abundant versatility of his nature, he himself had many, ranging from literature to optics, from history and biography to social science. Lord Brougham is even said to have written a novel; and the remarkable story of the 'Man in the Bell,' which appeared many years ago in 'Blackwood,' is reputed to have been from his pen. Intellectual hobbies, however, must not be ridden too hard--else, instead of recreating, refreshing, and invigorating a man's nature, they may only have the effect of sending him back to his business exhausted, enervated, and depressed.
