From "engines 1542:
Most important, it was Bacon who insisted that true
science has to be falsifiable. When we stop looking
for ways to prove our science wrong, we cease to be
scientists. That was Bacon's objection to the
alchemists. They reasoned as a debate team might
reason; they reasoned to win rather than to inquire.
What Bacon insisted on (and what any real scientist
must do) is to go where nature directs. A science
that begins with its own conclusions is no science at
all.

I know what he means, but i don't think that word fits. Comments?
