(_c_) A third view affirms that while there is a distinction between the Ego and the non-Ego (the me and the not-me), it is impossible to know anything about either in its essence. That they exist and that they are different are facts within our knowledge, but as to the absolute nature of mind and matter we can discover and believe nothing. The ultimate or absolute is beyond our reach, as is the infinite and unconditioned. We can have no knowledge of First Causes, or of the Ultimate Cause, or of the Absolute Cause. The infinite cannot even be apprehended, and those who undertake to learn or to speculate regarding the infinite engage in a task beyond their powers. Such knowledge is not practical. The term "God" is merely an expression for a mode of the unknowable, conveying no meaning to those who use it. The view thus expressed originated in concessions unhappily made by certain writers, as Sir William Hamilton and Dean Mansel, who, thinking to defend revealed religion, taught that reason cannot know the Infinite, and that therefore the Infinite must reveal Himself. Herbert Spencer took advantage of this concession, and carried it to a logical conclusion, when he argued that, if reason could not know or apprehend the Infinite by reason, neither could it by revelation. (_d_) Another class hold the view which is termed cosmogonies than that of Moses, whether contained in the sacred books of religions that have long existed, or professing to be based on modern scientific discovery, raise difficulties that are insuperable. Whence came matter if not from the creative word of God? To assign eternity to it is to invest it with an attribute that is Divine, and Pantheists carry such an explanation to its logical conclusion when they affirm that the universe is God. The existence of a single atom is an unfathomable mystery. Man cannot create or destroy even a particle of matter. How overwhelming, then, if we reject the simple statement of the Bible, is the mystery of the great universe, in whose extended space suns, planets, stars, and systems unceasingly revolve, and in which our own world is but a little speck. All things created point to God as their origin and source. "The invisible things of him from the creation of the world are clearly seen, being understood by the things that are made, even his eternal power and Godhead."[027]
