such contradictory assumptions as to the nature of our relations to our neighbors, we find it very easy to make absurd statements about the meaning of error. The contradiction of common sense has in fact just here much to do with the ethical illusion that we called the illusion of selfishness. To clear up this point will be useful to us, therefore, in more ways than one.
VI.
Disappointed once more in our efforts to understand how error is possible, we turn to another class of cases, which lie in a direction where, at least for this once, all will surely be plain. Errors about matters of fact or experience are certainly clear enough in nature. And as this class of errors is practically most important, the subtleties of our previous investigation may be dismissed with light heart so soon as we have gotten rid of the few little questions that will now beset us. It is to be noted that all errors about material objects, about the laws of nature, about history, and about the future, are alike errors about our actual or possible experiences. We expect or postulate an experience that at the given time, or under the given conditions, turns out to be other than it was postulated or expected to be. Now since our experiences not now present are objective facts, and capable of clear definition, it would seem clear that error concerning them is an easily comprehensible thing.
But alas! again we are disappointed. That errors in matters of experience are common enough is
