Be reasonable

In a discussion on Pharyngula about the necessity of reason, I wondered what would happen if I adopted Berkeley's subjective idealism:

Bishop Berkeley's existence was crammed
in his mind. His philosophy slammed
what he couldn't perceive.
I'll refuse to believe
in these bullets, so physics be dam-UGH!

And since I was in a mood for bashing the bishop:

Bishop Berkeley's religion subverted
his morals. His head was inserted
so far up his tush
that he started to push
Christian slavery: "Come, be converted!"
