When even the most strictly logical mind looks round and investigates the phenomena attending its own existence, perhaps the first fact to attract attention by its strongly marked prominence, is the remarkable loneliness of man. He stands alone. He may have brethren, but they are far below, and like Joseph’s seen in the dream, must bow the knee to his state. There extends, as it were, behind him a vast army of bird, beast, reptile, fish, and insect, thronging the broad earth in countless myriads, whose ancestry goes back into periods of time which cannot be expressed by notation. And every one of these, from the tiniest insect to the majestic elephant, is man’s intellectual inferior; so that he stands alone on a pedestal on the apex of a huge pyramid of animal life. He looks back—there are millions of inferior creatures. He looks forward—where is his superior? His mind easily grasps the idea of a superior, but where is it? He cannot see, feel, touch, or in any way indisputably prove the existence of a superior being, or race of beings. Yet the mind within is so wonderful and so complex, that it _will_ not accept the conclusion that he really stands alone; that he is the completion and the keystone of creation. A little thought convinces him of his own shortcomings, tells him how far he is from perfection, and the analogy of all things teaches him almost instinctively to look above into the Unknown for a superior being, or a race of beings. It is contrary to all reason and logic, to all analogy and all imagination, that there should be so many myriads behind, and nothing in _front_. There must be beings in front of him in the scale of existence, just as he is in front of the beings in his rear. Where are they? The answer to that question has peopled the whole universe with invisible beings. The solid earth beneath our feet has, according to one form of mythology, its gnomes and dwarfs, low of stature, grimy of aspect, but mighty in strength; or it has its Pluto and its Proserpine, its Titans struggling under Etna. The air and the sky above us teem with such shapes; they follow us night and day as our good and evil genii, or they engage in mighty battles—Armageddons of the angels in the empyrean, echoes of whose thundering charges reach our ears on earth.
