Though he is advising the parliamentarians, Gould's lines refer equally to himself.
"Submission to the inevitable" is the acceptance of life as a ceaseless
futile combat, while the "whole extent" of his own "surrender"
is his abandonment of saving idealism. As he has resolved to go on using his wealth
without it, in the amoral fashion of a buccaneer, there is no need for him to
"exhibit pointedly" his change. Translated, his line means something
like, "Life may be an amoral power struggle, but if our opponent in that
struggle is Pedro Montero, we have every chance of winning."
