me, 'What is Man'? It is the postulate already
mentioned in connection with his reading of Lecky, that every human
action, bad or good, is the result of a selfish impulse; that is to say,
the result of a desire for the greater content of spirit. It is not a
new idea; philosophers in all ages have considered it, and accepted or
rejected it, according to their temperament and teachings, but it was
startling and apparently new to the Monday Evening Club. They scoffed
and jeered at it; denounced it as a manifest falsity. They did not quite
see then that there may be two sorts of selfishness--brutal and divine;
that he who sacrifices others to himself exemplifies the first, whereas
he who sacrifices himself for others personifies the second--the divine
contenting of his soul by serving the happiness of his fellow-men. Mark
Twain left this admonition in furtherance of that better sort:

"Diligently train your ideals upward, and still upward, toward a summit
where you will find your chiefest pleasure, in conduct which, while
contenting you, will be sure to confer benefits upon your neighbor and
the community."

It is a divine admonition, even if, in its suggested moral freedom, it
does seem to conflict with that other theory--the inevitable sequence
of cause and effect, descending from the primal atom. There is seeming
irrelevance in introducing this matter here; but it has a chronological
relation, and it presents a mental aspect of the time. Clemens was
forty-eight, and becoming more and more the philosopher; also, in logic
at least, a good deal of a pessimist. He made a birthday aphorism on the
subject:

"The man who is a pessimist before he is forty-eight knows too much; the
man who is an optimist after he is forty-eight knows too little."

He was never more than a pessimist in theory at any time. In practice he
would be a visionary; a builder of dreams and fortunes, a veritable
Colonel Sellers to the end of his days.

CXLII

"LIFE ON THE MISSISSIPPI"

The Mississippi book was completed at last and placed in Osgood's hands
for publication. Clemens was immensely fond of Osgood. Osgood would
come down to Hartford and spend days discussing plans and playing
billiards, which to Mark Twain's mind was the proper way to conduct
business. Besides, there was Webster, who by this time, or a very little
later, had the word "publisher" printed in his letter-heads, and was
truly that, so far as the new book was concerned.
