Boing Boing has a great interview with Loren Coleman, the creator and curator of the International Cryptozoology Museum. Loren has been studying mythical creatures for over 50 years. When asked if he really believes in beasts like Bigfoot or the Loch Ness Monster, his answer is surprisingly respectably scientific: Loren says he doesn't, because belief "belongs in the providence of religion." Rather than believing or not believing in the weird and unusual creatures he studies, he merely keeps an open mind to accepting or denying evidence after a scientific investigation.
The interview is very interesting, as it not only explores the world of cryptozoology, but also examines the mind of someone completely dedicated to the pseudoscience.
