   It is curious that the Russians, calling themselves Christians, and like so many othere nominal christians throughout history, took no notice whatsoeverof the key parable of Jesus Christ himself, which taught that you shall love your neighbor as yourself, and that even those you have despised and hated are your neighbors. This has never made any difference to Christians, since the primary epiphenomena of any religion's foundation are the production and flourishment of hypocrisy, megalomania and psychopathy, and the first casualties of a religion's establishment are the intentions of its founder.

   Let's ask the question: Do epiphenomenons of emotions and feelings appear in these artificial brains? If so, where do they appear? It would be difficult to explain how such epiphenomenons might not appear in an artificial neural network, just as it does in a natural network.

   It is a necessary corollary of the view here advanced that in instinct as such consciousness is a mere epiphenomenon—a by-product, with no bearing whatever on the performance of the activity in so far as it is instinctive.

   From the monistic standpoint there is a choice between two possible alternatives; either consciousness is a form of energy, like heat, etc., or it is merely a so-called epiphenomenon. […] It is essential to have a clear notion of what is meant by an epiphenomenon. […] It designates an accompanying incident of a process which is assumed to have no causal relation to the further development of the process. […] For many years I have tried to recognize some actual idea underneath the epiphenomenon hypothesis of consciousness, but it more and more seems clear to me that there is no idea at all, and that the hypothesis is an empty phrase, a subterfuge, which really amounts only to this—we can explain consciousness very easily by merely assuming that it does not require to be explained at all.

   In amenorrhœa, epistaxis is by no means unfrequent; and often relieves the anomalous symptoms, especially those referable to the encephalon, which are the results of the irregular hyperæmia thus induced. The same may be said of it as an epiphænomenon in febrile affections—inflammatory and adynamic,—of which conditions it is often an important symptom.
