That would make an interesting sci-fi story. I think I agree that our
evaluations of human intelligence may differ in character. Even a
hypothetical cognitive power is constrained by reality--he can't lie
to me about the laws of physics, or suggest an experiment by which I
can verify some hypothesis without allowing me or anyone else to try
to duplicate it. And he can't convince me that the evidence of my own
senses is not what it is.
I certainly recognize that I can be emotionally motivated. But let's
say our theoretical "good" power whom I have caged is, as you say,
"capable of saving me" from the "bad" power that deceived me into
granting its freedom. Could it not them use the same deceits, as well
as rational argument, to gain its own freedom, since it knows that
the result of that will be good? Deceit in defense of self and others
is quite moral, as it would discover (since even my puny brain can
discover that--when the crazed terrorist points an Uzi at me and shouts
"I hate Americans! Where are you from?", I would not hesitate a moment
to proudly, morally lie "Je suis de Quebec, monsieur!")
