Why is it, in spite of all the mirrors in existence, no man really knows what he looks like, and, therefore, cannot picture in his mind his own person as he pictures that of an acquaintance? This is a difficulty which is thwarted at the very outset by gnothi sauton—know thyself.
This is undoubtedly partly due to the fact that a man can only see himself in the glass by looking straight towards it and remaining quite still; whereby the play of the eye, which is so important, and the real characteristic of the face is, to a great extent, lost. But co-operating with this physical impossibility, there appears to be an ethical impossibility analogous to it. A man cannot regard the reflection of his own face in the glass as if it were the face of some one else—which is the condition of his seeing himself objectively. This objective view rests with a profound feeling on the egoist's part, as a moral being, that what he is looking at is not himself; which is requisite for his perceiving all his defects as they really are from a purely objective point of view; and not until, then can he see his face reflected as it really and truly is. Instead of that, when a man sees his own person in the glass the egoistic side of him always whispers, It is not somebody else, but I myself, which has the effect of a noli me tangere, and prevents his taking a purely objective view. Without the leaven of a grain of malice, it does not seem possible to look at oneself objectively.
No one knows what capacities he possesses for suffering and doing until an opportunity occurs to bring them into play; any more than he imagines when looking into a perfectly smooth pond with a mirror-like surface, that it can tumble and toss and rush from rock to rock, or leap as high into the air as a fountain;—any more than in ice-cold water he suspects latent warmth.
That line of Ovid's,
"Pronaque cum spectent animalia cetera terram,"
is only applicable in its true physical sense to animals; but in a figurative and spiritual sense, unfortunately, to the great majority of men too. Their thoughts and aspirations are entirely devoted to physical enjoyment and physical welfare, or to various personal interests which receive their importance from their relation to the former; but they have no interests beyond these. This is not only shown in their way of living and speaking, but also in their look, the expression of their physiognomy, their gait and gesticulations; everything about them proclaims in terram prona! Consequently it is not to them, but only to those nobler and more highly endowed natures, those men who really think and observe things round them, and are the exceptions in the human race, that the following lines are applicable:
"Os homini sublime dedit coelumque tueri
Jussitt et erectos ad sidera tollere vultus."
