This is probably one of the most popular quotations in Shaw's repertoire. Indeed, photographs like this one abound on the Internet.
"But I dread success. To have succeeded is to
have finished one’s business on earth, like the male spider, who is killed by the female the moment he has succeeded in his courtship. I like a state of continual becoming, with a goal in front and not
behind. Then, too, I like fighting successful people; attacking them; rousing
them; trying their mettle; kicking down their sand castles so as to make them
build stone ones, and so on. It develops one’s muscles. Besides, one learns
from it: a man never tells you anything until you contradict him."
"Unless you contradict me, I shall assume that you prefer him to the available alternatives."
Of course, this tecnique - although effective - was not without detractors. As we can read in an article by Tom Miller (The Shavian 8.8, 2000), professor Harold J. Laski did not enjoy Shaw as a provocateur who fostered conflicting arguments, especially because Shaw seemed to have the sympathetic upper hand from his audience:
"He
talks as though he knows that Europe is listening at the keyhole to what he
says; and he has, consequently, a reckless disregard for truth where this is in
conflict with sensation that I really find a painful thing. And the adulation
which surrounds him is irritating beyond words. He says something which makes
you revolt; you contradict; and his audience looks at you as though you had
spat upon the Eucharist." (8 Jan. 1928)
I wonder if self-contradiction was Shaw's way of getting the truth out of himself?
