of man has not any word....

This experience had been produced by study of the first volume of
the Synthetic Philosophy, which an American friend had taught me
how to read. I did not find it easy reading; partly because I am a
slow thinker, but chiefly because my mind had never been trained to
sustained effort in such directions. To learn the "First Principles"
occupied me many months: no other volume of the series gave me equal
trouble. I would read one section at a time,--rarely two,--never
venturing upon a fresh section until I thought that I had made sure
of the preceding. Very cautious and slow my progress was, like that
of a man mounting, for the first time, a long series of ladders in
darkness. Reaching the light at last, I caught a sudden new vision of
things,--a momentary perception of the illusion of surfaces,--and from
that time the world never again appeared to me quite the same as it
had appeared before.

thrill of the moment, were recently revived for me by the reading of
the essay "Ultimate Questions," in the last and not least precious

contains his final utterance about the riddle of life and death,
as that riddle presented itself to his vast mind in the dusk of a
lifetime of intellectual toil. Certainly the substance of what he had
to tell us might have been inferred from the Synthetic Philosophy;
but the particular interest of this last essay is made by the writer's
expression of personal sentiment regarding the problem that troubles
all deep thinkers. Perhaps few of us could have remained satisfied
