Persons who assume to know all about God, as if He lived just around the corner, as Matthew Arnold said, will not find much comfort in Emerson's uncertainty and blind groping for adequate expression concerning Him. How can we put the All, the Eternal, in words? How can we define the Infinite without self-contradiction? Our minds are cast in the mould of the finite; our language is fashioned from our dealings with a world of boundaries and limitations and concrete objects and forces. How much can it serve us in dealing with a world of opposite kind--with the Whole, the Immeasurable, the Omnipresent, and Omnipotent? Of what use are our sounding-lines in a bottomless sea? How are we to apply our conceptions of personality to the all-life, to that which transcends all limitations, to that which is everywhere and yet nowhere? Shall we assign a local habitation and a name to the universal energy? As the sunlight puts out our lamp or candle, so our mental lights grow pale in the presence of the Infinite Light. We can deal with the solid bodies on the surface of the earth, but the earth as a sphere in the heavens baffles us. All our terms of over and under, up and down, east and west, and the like, fail us. You may go westward around the world and return to your own door coming from the east. The circle is a perpetual contradiction, the sphere a surface without boundaries, a mass without weight. When we ascribe weight to the earth, we are trying it by the standards of bodies on its surface--the pull of the earth is the measure of their weight; but the earth itself--what pulls that? Only some larger body can pull that, and the adjustment of the system is such that the centripetal and centrifugal forces balance each other, and the globes float as lightly as any feather.
