Live and act within the limit of your knowledge and keep expanding it to the
limit of your life. Redeem your mind from the hockshops of authority. Accept
the fact that you are not omniscient, but playing a zombie will not give you
omniscience—that your mind is fallible, but becoming mindless will not make
you infallible—that an error made on your own is safer than ten truths
accepted on faith, because the first leaves you the means to correct it, but
the second destroys your capacity to distinguish truth from error. In place of
your dream of an omniscient automaton, accept the fact that any knowledge man
acquires is acquired by his own will and effort, and that that is his
distinction in the universe, that is his nature, his morality, his glory.
