This paper compares and contrasts three views on the issue of 'solipsism' that were much discussed in the first half of the 20th century, namely those of Wittgenstein, Carnap and Reichenbach. While the paper deals mainly with early Wittgenstein, the so-called 'later Wittgenstein ' is seen as arguing that Carnap's Aufbau, and any similar 'solipsist' reinterpretation of the language must start with a notion of experience utterly different from the one we actually have. And this criticism actually coheres with Wittgenstein (...) 's views in the Tractatus. (shrink)

The document before you is by a member of a fanatical sect of heretical Ludwig scholars. Through a twist of fate it has fallen into my hands. I hesitate to make it public, since its circulation may do more harm than good. What speaks against publication is that it has the power to corrupt young minds. I do not take a light view of the dangers it poses in this regard. What speaks in favor of publication is the fact that (...) these people must be stopped. Through their pamphlets and brochures they continue to attract more converts everyday. The importance of this document lies in the fact that it brings to light some of the more esoteric doctrines of the sect, revealing the vulnerable theological underbelly of their creed. It also speaks of quar- relling within the infidel camp. There are even suggestions that the author fears that he himself may be excommunicated by an up-and-coming generation of zealots. He pleads here for a mild interpretation of their creed. (Oblivious to the stench of his own blasphemies, he even imagines entering into dialogue with mainstream Ludwig scholars!) My main aim in making this text generally available is that more learned men than I may make a study of it. A sound theological thrashing of the author’s own (according to him, mild!) version of the creed is devoutly to be wished. But my fondest hope is that, in the hands of one of our finer Ludwig scholars, it might become a weapon that can be turned against the infidel camp. I have a Trojan horse maneuver in mind here. A cunningly crafted pseudonymous publication, addressing some of the niceties of their more peculiar doctrines, under the pretence of attempting to heal the looming schism in their sect, ought to be able to bust it wide open. One particularly confusing feature of the document is that the author occasionally adopts a heavily ironical tone, actually going so far as to refer to himself as an infidel, etc., though without apparently the least appreciation of the fact that the heavier he allows his irony to become, the closer he comes finally to speaking the truth..
