Mind / Brain

[Angrboda]

By way of comparison, early religion looked at what they knew from the world around them and concluded "god". At the time, it was a reasonable assumption. So that's all I am saying about mind/brain. With current knowledge, it is reasonable to conclude they are one and the same.

So, you're arguing that because an analogous deduction was faulty, we should have confidence in this one? Not sure I follow your logic here, nor that I would agree that the situations are analogous. (Partly due to specific features of the respective problem spaces, and partly because it sounds to be coming from a position of ignorance concerning the history of various religions, and specifically the philosophical cultures surrounding them.) Moreover, we have better knowledge of the ways in which such reasoning can go wrong which are specifically applicable to this question, disregarding those "reasonable" ideas would make your conclusion other than that which is most reasonable; that would make your conclusion somewhat irrational and unreasonable.
