After the choice of nutrition, the choice of climate and locality, the third matter concerning which one must not on any account make a blunder, is the choice of the manner in which one _recuperates one's strength._ Here, again, according to the extent to which a spirit is _sui generis,_ the limits of that which he can allow himself--in other words, the limits of that which is beneficial to him--become more and more confined. As far as I in particular am concerned, _reading_ in general belongs to my means of recuperation; consequently it belongs to that which rids me of myself, to that which enables me to wander in strange sciences and strange souls--to that, in fact, about which I am no longer in earnest. Indeed, it is while reading that I recover from _my_ earnestness. During the time that I am deeply absorbed in my work, no books are found within my reach; it would never occur to me to allow any one to speak or even to think in my presence. For that is what reading would mean.... Has any one ever actually noticed, that, during the period of profound tension to which the state of pregnancy condemns not only the mind, but also, at bottom, the whole organism, accident and every kind of external stimulus acts too acutely and strikes too deep? Accident and external stimuli must, as far as possible, be avoided: a sort of walling-of-one's-self-in is one of the primary instinctive precautions of spiritual pregnancy. Shall I allow a strange thought to steal secretly over the wall? For that is what reading would mean.... The periods of work and fruit-fulness are followed by periods of recuperation: come hither, ye delightful, intellectual, intelligent books! Shall I read German books?... I must go back six months to catch myself with a book in my hand. What was it? An excellent study by Victor Brochard upon the Greek sceptics, in which my Laertiana[1] was used to advantage. The sceptics!--the only _honourable_ types among that double-faced and sometimes quintuple-faced throng, the philosophers!.... Otherwise I almost always take refuge in the same books: altogether their number is small; they are books which are precisely my proper fare. It is not perhaps in my nature to read much, and of all sorts: a library makes me ill. Neither is it my nature to love much or many kinds of things. Suspicion or even hostility towards new books is much more akin to my instinctive feeling than "toleration," _largeur de cœur,_ and other forms of "neighbour-love." ... It is to a small number of old French authors, that I always return again and again; I believe only in French culture, and regard everything else in Europe which calls itself "culture" as a misunderstanding. I do not even take the German kind into consideration.... The few instances of higher culture with which I have met in Germany were all French in their origin. The most striking example of this was Madame Cosima Wagner, by far the most decisive voice in matters of taste that I have ever heard.
