him," such a state of mind must necessarily be not only inconvenient but repulsive; and hence we have no right to feel surprised when an attempt is made to expose it to popular odium, or to fasten on those who entertain it injurious or opprobrious epithets. The old-standing feud, of which Plato speaks, between poetry and philosophy, has in great measure been transferred, in these latter times, to philosophy and theology. But in both cases the antagonism is an unnecessary one. The highest art is compatible with the most profound speculation. And so we may venture to hope that the simple love of truth, combined, with the charity "which never faileth," will lead men not further away from the Divine presence, but nearer to, and into it. Here I thankfully take leave of the mass of controversial literature, in the writing of which so much of Locke's latter life was spent. The controversies were not of his own seeking, and, from all that we know of his temper and character, must have been as distasteful to him as they are wearisome to us. But prolonged and reiterated controversy was of the habit of the time, and no man who cared candidly and unreservedly to express his opinions on any important question could hope to escape from it. * * * * * In the autumn of 1697, while the controversy with Stillingfleet was at its hottest, Locke wrote to Molyneux:--"I had much rather be at leisure to make some additions to my book of Education and my Essay on Human Understanding, than be employed to defend myself against the groundless, and, as others think, trifling quarrel of the bishop." He was at this time engaged on preparing the fourth edition of the _Essay_ for the press. In addition to this task, or rather as part of it, he was also employing himself on writing the admirable little tract on the Conduct of the Understanding, the contents of which I shall notice in a subsequent chapter. This treatise, which was not published till after his death, was originally intended as an additional chapter to the _Essay_. Speaking of it in one of his letters to Molyneux, he says:--"I have written several pages on this subject; but the matter, the farther I go, opens the more upon me, and I cannot yet get sight of any end of it. The title of the chapter will be 'Of the Conduct of the Understanding,' which, if I shall pursue as far as I imagine it will reach, and as it deserves, will, I conclude, make the largest chapter of my Essay." It did not, however, appear in the new edition, nor did Locke ever reduce its parts into order, or put the finishing stroke to it. He may, perhaps, have intended to revise it for a subsequent edition of the _Essay_, but the fourth was the last which appeared during his lifetime. * * * * *
