So, explain how you prove a negative, then.

subjective ( P ) Pronunciation Key (sb-jktv)
adj. Proceeding from or taking place in a person's mind rather than the external world: a subjective decision.Particular to a given person; personal: subjective experience. Moodily introspective. Existing only in the mind; illusory. rational ( P ) Pronunciation Key (rsh-nl)adj. Having or exercising the ability to reason. Of sound mind; sane. Consistent with or based on reason; logical: rational behavior. See Synonyms at logical. Using these definitions, I don't see how that because something is subjective it cannot be rational. If something proceeds from, or takes place in, my mind while I am of sound mind, or have the ability to reason, then, according to these definitions, said thing (ie a belief in god) could be both subjective and rational.

It is impossible to prove a negative. Sure it is, ever hear of not guilty verdicts.

Let's study this and see what we make of it. I am going to copy it down:
It is agreed on all hands that reason, and even sentience, and life itself are late comers in Nature. If there is nothing but Nature, therefore, reason must have come into existence by a historical process. And of course, for the Naturalist, this process was not designed to produce a mental behavior that can find truth. There was no Designer; and indeed, until there were thinkers, there was no truth or falsehood. The type of mental behavior we now call rational thinking or inference must therefore have been "evolved" by natural selection, by the gradual weeding out of types less fitted to survive.
Once, then, our thoughts were not rational. That is, all our thoughts once were, as many of our thoughts still are, merely subjective events, not apprehensions of objective truth. Those which had a cause external to ourselves at all were (like our pains) responses to stimuli. Now natural selection could operate only by eliminating responses that were biologically hurtful and multiplying those which tended to survival. But it is not conceivable that any improvement of responses could ever turn them into acts of insight, or even remotely tend to do so. The relation between response and stimuli is utterly different from that between knowledge and the truth known. Our physical vision is a far more useful response to light than that of the cruder organisms which have only a photo-sensitive spot. But neither this inprovement nor any possible improvements we can suppose could bring it an inch nearer to being a knowledge of light.

Firstly it is widely accepted that evolution can produce a remarkable range of physical adaptions despite not being desiged to do so. That it could also produce mental adaptions is a reasonable inference and thus the question of whether the process is "designed" to produce a particular result is something of a red herring.
Note also that Lewis does not even attempt to offer any explanation for the origin of reasoning capabilities. Any potential designer must posess reasoning capabilities, and if reasoning capabiities must be the result of design (even at one or more removes) we hit an infinite regress. The situation, then is already weighted in Lewis' behaviour since he avoids answering the larger question placing whatever explanation he has (if indeed he has one !) beyond criticism. The second paragraph is simply an arrgument from personal incredulity. However it would be equally valid - or rather equally invalid - to reject Lewis' idea of a creator on the same grounds. Thus Lewis' argument boils down to a purely subjective assessment. Moreover there is no sign that his subjective assessment of the possibility of reasoning capabilities evolving (despite the fact that they clearly are advantageous) is based on anything like an adequate assessment of the issue. Indeed there is no doubt that similar arguments could be made for any complex adaption - even if reasonable lines of evolutiuon are well-known to the experts they could be hard, indeed, for the uninformed layman - like Lewis - to explain (the evolution of the human eye is a common example). Thus Lewis' argument against an evolutionary explanation carries little weight. Thus what Lewis' argument comes down to is no more than his personal bias in favour of a belief in God. He presents no positive argument other than God's (assumed) capability and willingness to produce the result we see. Yet that is precisely what he must do - even if his argument against evolution were valid it still relies on the assumption that that there are no other alternatives to God - an assumption which is certainly questionable and would be very difficult to justify.

It is impossible to prove a negative. Sure it is, ever hear of not guilty verdicts. A legal verdict is not the same as logical proof. It isn't even the same as legal proof. A court case can have no proof, but still a verdict. What is meant by "it is impossible to prove a negative" is that it is logically impossible to prove absolutely that something does not exist or is not the case. We are all atheists about most of the gods that humanity has ever believed in. Some of us just go one god further. - Richard Dawkins

What is meant by "it is impossible to prove a negative" is that it is logically impossible to prove absolutely that something does not exist or is not the case. So then is it impossible to prove a positive?

What is meant by "it is impossible to prove a negative" is that it is logically impossible to prove absolutely that something does not exist or is not the case. one can never be sure there are no ghosts under the bed.

quote: I'll remind you that part of the definition of "subjective" you provided was "Existing only in the mind; illusory". I'll also mention that a key part of rational descisions is the use of logic, and your God of the Gaps logic is poor logical reasoning.

It is impossible to prove a negative. quote: Notice how they are called not guilty verdicts rather than innocent verdicts. So, please walk us through the logical proof of a negative, please.

A legal verdict is not the same as logical proof. It isn't even the same as legal proof. A court case can have no proof, but still a verdict. quote: No, it isn't. There is a lot of squishy language in the law like "preponderance of evidence", and "reasonable doubt", etc. For example, the OJ Simpson criminal trial returned a verdict of not guilty. Does that mean we can all be 100% sure that he didn't kill Nicole Brown?
What is meant by "it is impossible to prove a negative" is that it is logically impossible to prove absolutely that something does not exist or is not the case. quote: Exactly. We are not onmicient, we do not have all knowledge, so we cannot know that there are no ghosts under the bed. We do not have any evidence for there being ghosts under the bed, but that could be just because we cannot ever detect them, or perhaps have not developed the technology to detect them yet.

DHA writes: So then is it impossible to prove a positive? Of course not. You need only produce one tangible example of an invisible (hence 'tangible') pink unicorn to logically prove that an invisible pink unicorn exists. But if it does not exist, there's nothing you can do to prove it. You can't produce the evidence, because something that doesn't exist usually doesn't leave much evidence.

What beliefs of mine are irrational? Where I said we should all 'play nice'? That's not irrational, it's from experience, here in the real world. Things that are not here in the real world, like gods, do not exist for me until someone can produce evidence of such things.
