Mindless Commanders?

[Ygorl]

"Reason: the power of the mind to think, understand, and form judgments by a process of logic" - this is getting a bit philosophical, perhaps, but could such power arise without a mind? Maybe from a really powerful computer, say? I can certainly imagine such a device evaluating a battlefield and issuing orders; at what point does that become thinking? Does that mean it has a mind? I think, anyway, that there's enough philosophical gray area that one can reasonably imagine a construct reasoning without having a conventionally-understood mind (that would be subject to twisting, damaging, corrupting...)
