When responding to a statement of pure unsubstantiated opinion, what style of response do you think would be more appropriate? Ultimately, regardless of style, the substance is: My opinion differs, and you are entitled to yours.

Alfredo did not initiate the philosophical discussion about thinking computers--you did. You initiated the discussion of philosophy when you started talking past Alfredo's points regarding automated theorem proving (which computers do all the time thanks in no small part to Dijkstra) when you invoked Dijkstra's name and quoted his (in)famous "submarine" observation.

You have presented a vigorous argument against anthropomorphizing computers. However, the other discussion participant did not anthropomorphize them, which makes your little pissing match rather pointless.

I am sure you have the courage and the intellectual honesty to go back to news:e4330f45.0306120712.155386c1_at_posting.google.com and to observe that Alfredo did nothing to anthropomorphize computers, did not in any way imply that computers think and did not introduce philosophy with his strictly factual observation regarding automated theorem proving. Costin, I know you have the balls to admit when you make a mistake, and I think now is a good time to behave accordingly.

If you decide to respond to what Alfredo actually said in that message and not to some imagined philosophical argument, you might move the discussion in the direction of something truly illuminating. And who knows? You might inspire some anonymous lurker to pursue a path that leads to some truly important result.
