Abstract

When we climb in the high places of the earth, plodding slowly at mountaineer's pace with crampons on our boots, that we may keep foothold on the blue ice, we should stop from time to time and, steadying ourselves with our ice-axe for a moment, raise our downbent eyes, weary with guiding our steps between crevasses, to the great peaks we would conquer, and see, too, the foot hills we have left behind. Only by gazing thus can the Alpine climber find values, and often he catches too, just then, a glimpse of beauty. So it is profitable to turn from our work in laboratories and among the sick, to survey the general state of our knowledge in larger sweep. We cannot hope to have added by our deliberations to-day anything of solving value in this ultimate problem. But we clarify to ourselves the state of our small knowledge and the extent of our nescience, and, though we may throw on these matters no more light than that which Milton tells us shines in Hell, “enough to make darkness visible,” yet it were well done
