 wont to show herself utterly wayward and reckless; and though in all cases the vital informing principle is derived from her, yet to determine the right degree and the right moment, and to contribute the precision of practice and experience, is the peculiar province of scientific method. The great passions, when left to their own blind and rash impulses without the control of reason, are in the same danger as a ship let drive at random without ballast. Often they need the spur, but sometimes also the curb. The remark of Demosthenes with regard to human life in general,—that the greatest of all blessings is to be fortunate, but next to that and equal in importance is to be well advised—for good fortune is utterly ruined by the absence of good counsel,—may be applied to literature, if we substitute genius for fortune, and art for counsel. Then, again (and this is the most important point of all), a writer can only learn from art when he is to abandon himself to the direction of his genius.

These are the considerations which I submit to the unfavourable critic of such useful studies. Perhaps they may induce him to alter his opinion as to the vanity and idleness of our present investigations.
