And the ignorant by-stander prays that the doctor may have grace given him and time for repentance; whilst his more liberal companion reproves his want of charity, observing that travellers into far countries have always had a license for lying, as a sort of tax or fine levied for remunerating their own risks; and that great astronomers, as necessarily far travellers into space, are entitled to a double per centage of the same Munchausen privilege. Great is the mystery of Space, greater is the mystery of Time; either mystery grows upon man, as man himself grows; and either seems to be a function of the godlike which is in man. In reality the depths and the heights which are in man, the depths by which he searches, the heights by which he aspires, are but projected and made objective externally in the three dimensions of space which are outside of him. He trembles at the abyss into which his bodily eyes look down, or look up; not knowing that abyss to be, not always consciously suspecting it to be, but by an instinct written in his prophetic heart feeling it to be, boding it to be, fearing it to be, and sometimes hoping it to be, the mirror to a mightier abyss that will one day be expanded in himself. Even as to the sense of space, which is the lesser mystery than time, I know not whether the reader has remarked that it is one which swells upon man with the expansion of his mind, and that it is probably peculiar to the mind of man. An infant of a year old, or oftentimes even older, takes no notice of a sound, however loud, which is a quarter of a mile removed, or even in a distant chamber. And brutes, even of the most enlarged capacities, seem not to have any commerce with distance: distance is probably not revealed to them except by a _presence_, viz., by some shadow of their own animality, which, if perceived at all, is perceived as a thing _present_ to their organs. An animal desire, or a deep animal hostility, may render sensible a distance which else would not be sensible; but not render it sensible _as_ a distance. Hence perhaps is explained, and not out of any self-oblivion from higher enthusiasm, a fact that often has occurred, of deer, or hares, or foxes, and the pack of hounds in pursuit, chaser and chased, all going headlong over a precipice together. Depth or height does not readily manifest itself to _them_; so that any _strong_ motive is sufficient to overpower the sense of it. Man only has a natural function for expanding on an illimitable sensorium, the illimitable growths of space. Man, coming to the precipice, reads his danger; the brute perishes: man is saved; and the horse is saved by his rider.
