what are the indications that people have souls? What else has souls?

and I don't think the abolition of naive dualism has much affect on
the legal system (nor should it). The legal system runs quite fine
without souls.

hradware/software emergent behaviour. I don't believe in metaphysical
souls or minds but I do think the behaviour of complex things (brains,
laptops) cannot be predicted based on just a description of the
hardware.

sorry, you're hacking their brains with magnets! And if you forced
them to ingest a pint of whiskey they wouldn't be able to freely
choose to walk in a straight line either!

again, its not what I believe and I'm not sure its what "most" people
believe. I know a fair number of atheists and I doubt they think
they've got a "soul".

Hmm, so free will "does not exist".

OK, so let's change either 1 or 2:

1) Imprison all animals who kill humans (33 years should be long
enough).
2) Let free all humans who were motivated (somehow) to kill other
humans.

Which one do you prefer?

I don't believe in hard determinism (i.e., I do accept that quantum
indeterminacy exists). However, there is no existing evidence that
quantum indeterminacy operating in the brain is equivalent to free
will. Moreover, as Ron points out elsewhere in this subthread, quantum
indeterminacy in the brain may very well amount to the equivalent of
classical determinism.

On the contrary, we have a great deal of evidence that our subjective
evaluation of the freeness of our choices is wildly inaccurate.

I wrote "recast" our legal system, not eliminate. In particular, legal
theories of criminal penalties typically deal with several types of
penalty, among them, deterrence (as you note), incapacitation ("keeping
criminals off the street"), rehabilitation (re-training, or
re-educating criminals so they become less likely to commit future
offenses), and retribution ("punishing the morally wicked"). If we have
no free will, then any penalties based on retribution become pointless,
even cruel, like sentencing a slug to 40 lashes for wickedly eating
your garden lettuce.

Ralph
