the intelligence directly impedes firmness of character and resolution of will. Hence this kind of eminence is not so abnormal, and is a hundred times less rare than the former kind; and accordingly we see great generals and great ministers appear in every age, whenever the merely external conditions are favourable to their efficiency. Great poets and philosophers, on the other hand, leave centuries waiting for them; and yet humanity may be contented even with this rare appearance of them, for their works remain, and do not exist only for the present, like the achievements of those other men. It is also quite in keeping with the law of the parsimony of nature referred to above that it bestows great eminence of mind in general upon very few, and genius only as the rarest of all exceptions, while it equips the great mass of the human race with no more mental power than is required for the maintenance of the individual and the species. For the great, and through their very satisfaction, constantly increasing needs of the human race make it necessary that the great majority of men should pass their lives in occupations of a coarsely physical and entirely mechanical description. And what would be the use to them of an active mind, a glowing imagination, a subtle understanding, and a profoundly penetrating intellect? These would only make them useless and unhappy. Therefore nature has thus gone about the most costly of all her productions in the least extravagant manner. In order not to judge unfairly one ought also to settle definitely one's expectations of the mental achievements of men generally from this point of view, and to regard, for example, even learned men, since as a rule they have become so only by the force of outward circumstances, primarily as men whom nature really intended to be tillers of the soil; indeed even professors of philosophy ought to be estimated according to this standard, and then their achievements will be found to come up to all fair expectations. It is worth noticing that in the south, where the necessities of life press less
