[Don Quixote] witnesses the same events as everyone else, but comes away
with a completely different set of facts. He reasons soundly from what
he sees, but his perception is radically different from how everyone
else perceives....
Once Quixote's stories lead him to believe that the chain gang is more
likely to be disguised victims of injustice than criminals and cons, the
empirical fact of their chains reinforces, rather than undermines, his
belief.
