Writers of imaginative literature have found in practice that even the creative faculty might be commanded. Charles Baudelaire, who had the poetical organization with all its worst inconveniencies, said nevertheless that "inspiration is decidedly the sister of daily labor. These two contraries do not exclude each other more than all the other contraries which constitute nature. Inspiration obeys like hunger, like digestion, like sleep. There is, no doubt, in the mind a sort of celestial mechanism, of which we need not be ashamed, but we ought to make the best use of it. If we will only live in a resolute contemplation of next day's work, the daily labor will serve inspiration." In cases where discipline is felt to be very difficult, it is generally at the same time felt to be very desirable. George Sand complains that although "to overcome the indiscipline of her brain, she had imposed upon herself a regular way of living, and a daily labor, still twenty times out of thirty she catches herself reading or dreaming, or writing something entirely apart from the work in hand." She adds that without this frequent intellectual _flânerie_, she would have acquired information which has been her perpetual but unrealized desire. It is the triumph of discipline to overcome both small and great repugnances. We bring ourselves, by its help, to face petty details that are wearisome, and heavy tasks that are almost appalling. Nothing shows the power of discipline more than the application of the mind in the common trades and professions to subjects which have hardly any interest in themselves. Lawyers are especially admirable for this. They acquire the faculty of resolutely applying their minds to the dryest documents, with tenacity enough to end in the perfect mastery of their contents; a feat which is utterly beyond the capacity of any undisciplined intellect, however gifted by Nature. In the case of lawyers there are frequent intellectual repugnances to be overcome; but surgeons and other men of science have to vanquish a class of repugnances even less within the power of the will--the instinctive physical repugnances. These are often so strong as to seem apparently insurmountable, but they yield to persevering discipline. Although Haller surpassed his contemporaries in anatomy, and published several important anatomical works, he was troubled at the outset with a horror of dissection beyond what is usual with the inexperienced, and it was only by firm self-discipline that he became an anatomist at all.
