But wasn't this a queer question to ask? Can't I believe that someone else has pains? Is it not quite easy to believe this? ‒ ‒ ‒ Is it an answer to say that things are as they appear to common sense? ‒ ‒ ‒ Again, needless to say, we don't feel these difficulties in ordinary life. Nor is it true to say that we feel them when we scrutinize our experiences by introspection, or make scientific investigations about them. But somehow, when we look at them in a certain way, our expression is liable to get into a tangle. It seems to us as though we had either the wrong pieces, or not enough of them, to put together our jig-saw puzzle. But they are all there, only all mixed up; and there is a further analogy between the jig-saw puzzle and our case: It's no use trying to apply force in fitting pieces together. All we should do is to look at them carefully and arrange them.
