The
four main ideas for scientific
progress are:
①
Never accept anything as true
until all reasons for doubt can
be ruled out.
②
Divide
problems into as many parts
as possible and necessary to
provide an
adequate solution.
③
Thoughts should be ordered,
starting with the simplest and
easiest to know, ascending
little by little, and, step by
step, to more complex knowledge.
④
Make enumerations so complete,
and reviews so general, that
nothing is omitted.
