We fancy there are many independent sciences, because we stand half-way up on different mountain-peaks, calling to each other from isolated stations. The mists hide from us the foot of the range beneath us, the depths of primary analysis to which none can reach, or we should see that all the peaks were but offsets of one vast mountain-base, and in their inmost root but One! And the clouds which float between us and the heaven shroud from us the sun-lighted caps themselves -- the perfect issues of synthetic science, on which the Sun of Righteousness shines with undimmed lustre -- and keep us from perceiving that the complete practical details of our applied knowledge is all holy and radiant with God's smile. And so, half-way up, on the hillside, beneath a cloudy sky, we build up little earthy hill-cairns of our own petty synthesis, and fancy them Babel-towers whose top shall reach to heaven!
