This paper presents The Unity of Science by answering four fundamental concerns about nature: 1) The ultimate property of everything— the intrinsicality of nature is not only logicality, but also logicality’s non-absoluteness; 2) The ultimate impact of everything— the “General Impact of Nature” (GIN) is what can explain mental processes physically; 3) The proto-structure of everything— the “architect of everything” is with two three-point group concepts; 4) One architecture to host everything— the “general model of nature” provided a whole (...) picture of nature by particularly describing what consciousness is. With this unity, we have developed seven points to complete the unification of all knowledge. But all these are structured on reductionism and neutral monism. (shrink)
