1. Probability and Chance, Fritz Mauthner's Studies of Improbability

This is a much more important matter than we might suppose, for it demonstrates how extraordinarily difficult it can be, no matter how scientifically one proceeds, to avoid losing sight of reality as we pursue a train of thought. We must imbue our feelings with this realization and learn a great deal from just such an example. Two things are required as we mull it over. One is that we educate ourselves through an outstanding example of this kind to an awareness that the search for truth is far from easy, and that we badly need to develop a feeling for the fact that not just any thought sequence that strikes us at first glance as correct is actually a sound one. The more we can imbue ourselves with the feeling that we could err, that even at our most conscientious we might be wrong, the more easily will we avoid a rigid clinging to our own opinions, to a stubborn belief in the correctness of our views.
