I certainly do not deny that, if the books of the ancients who wrote about the art of painting still lay before our eyes, my design might be open to the false interpretation that I thought to find out something better than what was known unto them. These books, however, have been totally lost in the lapse of time; so I cannot be justly blamed for publishing my opinions and discoveries in writing, for that is exactly what the ancients did. If other competent men are thereby induced to do the like, our descendants have something which they may add to and improve upon, and thus the art of painting may in time advance and reach its perfection. II Whether we should exercise our intellects or logical sense alone upon the records and remains of past ages, or whether they may not be better employed for the exercise and edification of the imaginative faculties, would seem to be a question which, though they did not perhaps in set terms put to themselves, modern historians have very summarily answered; and I think answered wrongly. The records of the past, the records even of yesterday, are necessarily extremely incomplete; to make them at all significant something must be added by the historian. The 'perception' of probability is never exact; it varies with the mind between man and man; in the same man even before and after different experiences, &c. But even if the perception of the highest probability were practically exact, it would never suffice; for, as Aristotle says, "it is probable that many things should happen contrary to probability." From these facts it follows that the man who has the most exhaustive knowledge of what has actually survived, and what has been recorded, will not necessarily form the truest judgment on a question of history; it might always happen that the intuition of some unscholarly person was nearer the truth; still no man could ever decide between the two, nor would any sane man think it worth his while to take sides with either of them; such questions are most useful when they are left open. This is the case because the imagination is thus left freer to use such knowledge as it has for the edification of the character; and that model for our example or warning which the imagination constructs may always possibly be the truth. According to the balance in it of apparent probability, with edifying power it will beget conviction. Such a conviction may be doomed to be superseded sooner or later; its value lies in its potency while it lasts. The temper in which we look at our historical heritage is of more importance to us now than the exactitude of our vision; for this latter can never be proved, while the former approves itself by the fruit it bears within us. It is better, more fruitful, to feel with Dürer about the art of Ancient Greece than to know all that can be known of it to-day and feel a great deal less. "Character calls forth character," said Goethe; we may add, "even from the grave." Now that the physical
