Science, like any human endeavor, is limited by funding, imagination
and the interests of egos involved. Most funding is provided by
governments or corporations for purposes of furthering established
industry interests (that should be obvious), and new research is only
pursued if it is either economically viable or militarily useful.

Research in all other fields accept those approved by the
establishment (ANY OF THEM) will always be limited by interest (which
gets reduced by official ostracism and encouraged by kook clingers-on,
though they can still provide funding, usually don't though), danger
to established interests (viable free energy sources, if they exist,
threaten very rich and dangerous people, cheap home-made superweapons
a BIG NO NO, make your own medicines uh-nope, find out whats really
going on- they'll wipe your mind, or just out right kill you, or
convince you to watch some kind of "programming"... sorry for the
emotive juvenalism, but it is that bad), and of course access to data
and equiptment in proportion to avoiding the above mentioned dampeners
of real progress.

As far as crowley is concerned, i think some of his ideas are useful.
Taken too seriously it's a problem, but I still effective ideas all
the time, it helps buttress my own projekz. Gurdjieff made far more
sense, and "Bob" was just easier. Grant Morrison is just more
entertaining. I could go on. Damn it's a big world, and there are
hundreds, if not thousands of interesting ideas and people out there
to meet and learn from.
