Critias (107)

Crit.

I am sufficiently aware that the request I am about to make is decidedly presumptuous and less civil than is proper, but none the less it must be uttered. For as regards the exposition you gave, what man in his senses would attempt to deny its excellence? But what I must somehow endeavor to show is that the discourse now to be delivered calls for greater indulgence because of its greater difficulty. For it is easier, Timaeus, to appear to speak satisfactorily to men about the gods,

than to us about mortals. For when the listeners are in a state of inexperience and complete ignorance about a matter, such a state of mind affords great opportunities to the person who is going to discourse on that matter; and we know what our state is concerning knowledge of the gods. [*] But in order that I may explain my meaning more clearly, pray follow me further. The accounts given by us all must be, of course, of the nature of imitations and representations; and if we look at the portraiture of divine and of human bodies as executed by painters, in respect of the ease or difficulty with which they succeed in imitating their subjects in the opinion of onlookers, we shall notice in the first place that as regards the earth and mountains and rivers and woods and the whole of heaven, with the things that exist and move therein, we are content if a man is able to represent them with even a small degree of likeness; and further, that, inasmuch as we have no exact knowledge about such objects, we do not examine closely or criticize the paintings, but tolerate, in such cases, an inexact and deceptive sketch. On the other hand, whenever a painter tries to render a likeness of our own bodies, we quickly perceive what is defective because of our constant familiar acquaintance with them, and become severe critics of him who fails to bring out to the full all the points of similarity. And precisely the same thing happens, as we should notice, in the case of discourses: in respect of what is celestial and divine we are satisfied if the account pocesses even a small degree of likelihood, but we examine with precision what is mortal and human. To an account given now on the spur of the moment indulgence must be granted, should we fail to make it a wholly fitting representation; for one must conceive of mortal objects as being difficult, and not easy, to represent satisfactorily.
