21. Difficulty in delimitation of own
knowledge
I do not know what I do not know. It is
tempting to subconsciously think that we personally know everything that is
important to know, even in outline. This leads to a false sensation of
omniscience, conducive to intellectual blindness and an
unwillingness to accept new data. Albert Camus said that the only system
of thought that is Òfaithful to the originsÓ is one which
Ònotes its limitsÓ. We should always be keeping an eye out for unknown
unknowns, and realize that they must exist, even if we cannot currently imagine
what they are.
