Objectivism was a real turn off for me at first but I realized it
wasn't because of Rand. Whether one agrees with everything she had to
say or not she was a brilliant philosopher that provoked thought. The
problem was the church you mention. Collectivized Objectivism is a
contradiction in terms.
It's understandable why it happens though. Pining about the virtues of
some ideology tends to lead to collectivized action revolving around
that ideology. It's a focal point for common interests. She joked
about her "collective" but there was some contradiction there. She
herself politicized Objectivism (which leads to that exact sort of
collectivized action) rather than keeping it purely in the realm of
philosophical debate. (to let readers themselves decide their
individual interests)
For example, it might actual be someone's rational self-interest to
be a communist, a religious fundamentalist, or even Nazis.
Now I don't actually believe that but empiricism is part of reason not
purely speculative a priori moral theories. A claim of something is in
our interests is not actually the same as it being in our interests.
We cannot yet assert pure capitalism (or liberalism, or whatever) is
in our ideal self-interests with certainty with absolute confidence.
Complex moral and economic issues remain unresolved. This is not to
say these issues can't eventually be resolved but as it stands there
is still uncertainty.
Its funny. When I was a young man I thought I knew everything. As I
get older I realize more how little I actually know and just how
complex issues can be. It's easy to let hubris tell us we know
something but we are often just fooling ourselves by just letting out
egos take command rather than reason.
