Appendix

> If one wants to find out which theoretical position a supposed epistemological monist occupies, one need only put certain questions to him and compel him to answer them. For such a person will never willingly commit himself to an expression of opinion on these points, and will, moreover, seek by all means to evade answering direct questions, because every answer would show that epistemological monism cannot claim to be different from one or other of the three positions. These questions are as follows: > (1) Are things continuous or intermittent in their existence? If the answer is “continuous”, then one is dealing with some form of naïve realism. If the answer is “intermittent”, then one has transcendental idealism. But if the answer is that they are, on the one hand, continuous (as contents of the absolute consciousness, or as unconscious mental pictures, or as possibilities of perception), but on the other hand, intermittent (as contents of limited consciousness), then transcendental realism is established. > (2) When three people are sitting at a table, how many distinct tables are there: Whoever answers “one” is a naïve realist; whoever answers “three” is a transcendental idealist; but whoever answers “four” is a transcendental realist. Here, of course, it is assumed that it is legitimate to embrace such different things as the one table as a thing-in-itself and the three tables as perceptual objects in the three consciousnesses under the common designation of “a table”. If this seems too great a liberty to anyone, he will have to answer “one and three” instead of “four”. > (3) When two people are alone together in a room, how many distinct persons are there: Whoever answers “two” is a naïve realist. Whoever answers “four” (namely, one self and one other person in each of the two consciousnesses) is a transcendental idealist. Whoever answers “six” (namely, two persons as “things-in-themselves” and four persons as mentally pictured objects in the two consciousnesses) is a transcendental realist. > If anyone wants to show that epistemological monism is different from any of these three positions, he would have to give a different answer to each of these three questions; but I would not know what this could be.
