Now, as regards the second part of the principle set up thus the inheritance of the intellect from the mother, this enjoys a far more general acceptance than the first part, which in itself appeals to the _liberum arbitrium indifferentiæ_, while its separate apprehension is opposed by the doctrine of the simplicity and indivisibility of the soul. Even the old and popular expression “mother‐wit” shows the early recognition of this second truth, which depends upon the experience both with regard to small and great intellectual endowments, that they are the possession of those whose mothers proportionately distinguished themselves by their intelligence. That, on the other hand, the intellectual qualities of the father are not transmitted to the son is proved both by the fathers and the sons of men distinguished by the most eminent faculties, for, as a rule, they are quite ordinary men, without a trace of the paternal mental gifts. But if now an isolated exception to this experience, so often confirmed, should appear; such, for example, as is presented by Pitt and his father, Lord Chatham, we are warranted in ascribing it to accident, nay, obliged to do so, although, on account of the exceptional rarity of great talents, it is certainly an accident of a most extraordinary kind. Here, however, the rule holds good: it is improbable that the improbable _never_ happens. Besides, great statesmen (as was already mentioned in chapter 22) are so just as much through the qualities of their character, thus through what is inherited from the father, as through the superiority of their mind. On the other hand, among artists, poets, and philosophers, to whose works alone _genius_ is properly ascribed, I know of no case analogous to that. Raphael’s father was certainly a painter, but not a great one; Mozart’s father, and also his son, were musicians, but not great ones. However, it is indeed wonderful that the fate which had destined a very short life to both of these men, each the greatest in his own sphere, as it were by way of compensation, took care, by letting them be born already in their workshop, that, without suffering the loss of time in youth which for the most part occurs in the case of other men of genius, they received even from childhood, through paternal example and instruction, the necessary introduction into the art to which they were exclusively destined. This secret and mysterious power which seems to guide the individual life I have made the subject of special investigations, which I have communicated in the essay, “_Ueber die scheinbare Absichtlichkeit im Schicksale des Einzelnen_” (_Parerga_, vol. i.). It is further to be observed here that there are certain scientific occupations which certainly presuppose good native faculties, yet not those which are really rare and extraordinary; while the principal requirements are zealous efforts, diligence, patience, early instruction, sustained study, and much practice. From this, and not from the
