One of the recognized problems in research, any kind of research, is the repetition of a single original finding or opinion by other, later researchers as if those others had arrived at the finding or opinion independently. This, then, may result in an extensive bibliography of secondary sources for a position that, in fact, has only a single source. Obviously there is no problem with building on the work of others, but there isa problem if the original source was flawed.
The talking of allfreeflyingbirdshaspersistedwithoutinterruption in the past years in which I frequently changed my residence, and it persists to this day … I would now prefer to use the expression “talking bird” to “miraculously created bird” which is used in the text. Earlier on I thought I could not explain the talking of the birds other than by assuming that they were assuch created by miracle, that is to say were created anew each time. After what I have observed meantime I consider it more likely that they were birds produced by natural reproduction, into whose bodies the remnants of the “forecourts of heaven,” that is to say erstwhile blessed human souls, had been inserted in some supernatural way or were inserted anew each time. But that these souls [nerves] were actually inside the bodies of these birds [perhaps inaddition to the nerves which these birds naturally possess and in any case without awareness of their previous identity] remains as before without any doubt for me for reasons developed in the text.
