Everybody except of course Mückenheim knows that Russell's stance concerning foundations of mathematics was logicism; and with a little background knowledge about this philosophy it is quite clear what he means and why he must be concerned about the truth of that axiom in the above quotation. Without such background one simply can not understand it. Mückenheim is too stupid for this subject in any respect. He is even too stupid to imagine that e.g. Cantor's speech habits might be different from those of today, not even if he is told so for no less than 8 years. He can just cull quotations from wherever he finds them and have a kind of feeling whether he likes what he reads or not. But he can't understand anything, and he can't understand that he can't understand and so on ad infinitum. Usually idiots stop short at the second (those who at least know that they don't know much) or third (those exhibiting the DunningKruger effect) round of this but Mückenheim's idiocy has infinite deepness and thereby proofs the existence of actual infinity.
