Why does the equation have an imaginary form? What is the meaning of Planck's constant it the CONTEXT of the MWI? Just saying, as you do, that the SE is what it is just because, is adopting the same POSITIVIST attitude as the Copenhagen school. I am looking for the INTERPRETATION of this equation in terms of the MW. Is it possible to derive this equation from a PURELY COMPUTATIONALIST APPROACH? You say that psi can be written in terms of orthogonal (decoherent) functions. Are those functions equivalent to the individual worlds in the MW? If so, then we certainly have the ability to be affected by several such worlds simultaneously because of the phenomenon of superposition. What does this say about consciousness? Does consciousness have "thickness" across the MW? How does this fit with the ideas of Lewis and Kriepke? > > You still don't know what computationalism means?

Computationalism ASSUMES that certain computations give rise to consciousness. It does not EXPLAIN consciousness. And without a third person/ first person theory you can only talk about behaviors as observed from a third person point of view without ever describing what it is to be (yourself) conscious. George
