As I argued in "Beloved Son", a book about my son Brian and the subject of religious communes and cults, one result of proper early instruction in the methods of rational thought will be to make sudden mindless conversions — to anything — less likely. Brian now realizes this and has, after eleven years, left the sect he was associated with. The problem is that once the untrained mind has made a formal commitment to a religious philosophy — and it does not matter whether that philosophy is generally reasonable and high-minded or utterly bizarre and irrational — the powers of reason are suprisingly ineffective in changing the believer's mind.

Why do I get this image in my head of two C'thulus kissing?

F*ck yeah. That's got me in the weekend mood.

OH MY! How dare you put such a graphic and lurid picture on the internet? What's next?! You're going down a slippery slope!

Invertebrate ventral mating? Who woulda thunk? Wish I could've had this graphic last week! But I did find movies of the nautilus, BTW, and ran them during my Darwin Day Power Point. At my church, while showing some kids some ammonites, most fun I've had in weeks. As always, PZ, your site is an invaluable resource.....SH

Yeah, but they can't look each other in the eye.

Presumably a NaughtyLass and a NaughtyLad - unless PZ knows more about the incidences of (intended or accidental) homosexuality among cephalopods.
Accidental homosexuality? Would that be similar to Rev. Haggard?

I was thinking more in terms of the squid orgies in which tentacles and sperm packets go every which way.

It's so heartwarming in some very strange way.

Awwww~. Copulation isn't generally something I would describe as cute, but when it's a pair of nautilus, it's just adorable.
