Lewis and Nagel

 

In Lewis’s essay “Meditation in a  Toolshed Lewis distinguishes between looking ay and looking along.  Looking at is the third person scientific perspective, looking along is looking from the first person perspective. This is the issue that is the subject of Thomas Nagel’s famous “What it is Like to Be a Bat.” Many, from J. B. Watson to Patricia Churchland, have argued the uselessness of introspection as sub-scientific. Lewis, like Nagel, argues that this kind of dismissiveness cannot be sustained, and he does sao on the grounds that to do so would undermine the very reasoning process that grounds the scientific argument on which the dismissal is based.  He writes:

Having been so often deceived by looking along, are we not well advised to trust only to looking at? in fact to discount all these inside experiences? Well, no. There are two fatal objections to discounting them all. And the first is this. You discount them in order to think more accurately. But you can't think at all - and therefore, of course, can't think accurately - if you have nothing to think about. A physiologist, for example, can study pain and find out that it “is” (whatever is means) such and such neural events. But the word pain would have no meaning for him unless he had “been inside” by actually suffering. If he had never looked along pain he simply wouldn't know what he was looking at. The very subject for his inquiries from outside exists for him only because he has, at least once, been inside. This case is not likely to occur, because every man has felt pain. But it is perfectly easy to go on all your life giving explanations of religion, love, morality, honour, and the like, without having been inside any of them. And if you do that, you are simply playing with counters. You go on explaining a thing without knowing what it is. That is why a great deal of contemporary thought is, strictly speaking, thought about nothing - all the apparatus of thought busily working in a vacuum. The other objection is this: let us go back to the toolshed. I might have discounted what I saw when looking along the beam (i.e., the leaves moving and the sun) on the ground that it was “really only a strip of dusty light in a dark shed”. That is, I might have set up as “true” my “side vision” of the beam. But then that side vision is itself an instance of the activity we call seeing. And this new instance could also be looked at from outside. I could allow a scientist to tell me that what seemed to be a beam of light in a shed was “really only an agitation of my own optic nerves”. And that would be just as good (or as bad) a bit of debunking as the previous one. The picture of the beam in the toolshed would now have to be discounted just as the previous picture of the trees and the sun had been discounted. And then, where are you? In other words, you can step outside one experience only by stepping inside another. Therefore, if all inside experiences are misleading, we are always misled. The cerebral physiologist may say, if he chooses, that the mathematician's thought is “only” tiny physical movements of the grey matter. But then what about the cerebral physiologist's own thought at that very moment? A second physiologist, looking at it, could pronounce it also to be only tiny physical movements in the first physiologist's skull. Where is the rot to end? The answer is that we must never allow the rot to begin. We must, on pain of idiocy, deny from the very outset the idea that looking at is, by its own nature, intrinsically truer or better than looking along. One must look both along and at everything. In particular cases we shall find reason for regarding the one or the other vision as inferior. Thus the inside vision of rational thinking must be truer than the outside vision which sees only movements of the grey matter; for if the outside vision were the correct one all thought (including this thought itself) would be valueless, and this is self-contradictory. You cannot have a proof that no proofs matter. On the other hand, the inside vision of the savage's dance to Nyonga may be found deceptive because we find reason to believe that crops and babies are not really affected by it. In fact, we must take each case on its merits. But we must start with no prejudice for or against either kind of looking. We do not know in advance 3 whether the lover or the psychologist is giving the more correct account of love, or whether both accounts are equally correct in different ways, or whether both are equally wrong. We just have to find out. But the period of brow-beating has got to end.t
