The problem of the conscious for the consept of science of the materialistic evolution

One of the most debated topics of contemporary philosophy of mind is whether mental states which can be reached objectively and intuitively through the first person's perspective and consciousness in this respect can be a subject of objective science through the third person's perspective. Today some thought experiments which are mostly known and used as references aim to show the incompatibility of the existence of consciousness to the world view by referring to the conscious, this privileged access or the inner qualities. After opposing views are explained through analysis in this thesis, it will be explained how conscious organism existed in materialist universe over the conscious theory built by Daniel Dennett and how it can be a subject of objective science through the third person's perspective. Dennett, who step by step explained the existence of conscious organisms with the theory of Darwin's natural selection, it shows that conscious can scientifically be examined with a method he called Heterophenomenology. In the study finally, most known and referred thought experiments of the philosophy of mind, which aim to exclude conscious from materialist world view and therefore science, are all studied with Dennett's answer. That way, the idea is suggested that the matter of conscious can be explained scientifically; conscious is not outside the scope of scientific methodologies and concepts and it is not a supernatural concept.
