Your thoughts/feelings feel a certain way in so much as they affect your judgments of them. Your judgments become your beliefs/perceptions that you thought/felt said thoughts/feelings. These beliefs/perceptions affect your other thoughts/feelings (and any related beliefs/perceptions), as well as your behaviors and speech. In general, beliefs/perceptions that you exist independently of your brain demonstrate very little, excepting the fact that you hold said beliefs/perceptions and had thoughts/feelings leading to said beliefs/perceptions.
Neurological research has continuously found physical explanations for psychological phenomena. Thoughts/feelings and beliefs/perceptions, according to computational theory, could be implemented by a silicon robot as well as a biological human. These robots would seem to have thoughts/feelings in the same way that other humans seem to have them.
There would be reasons to suppose that these robots do not feel and only seem to feel, but these reasons would only be ‘correct’ in quite subjective and/or illusive realms: an individual’s beliefs/perceptions, a mythological faith, a piece of propaganda, and other realms with assumptions about the mind. In these realms, mystical explanations of the mind are indeed often ‘correct’ while material explanations are 'incorrect'.
The 'self' is very useful folk concept dependent on the physical world that may or may not be correct or consistent. So are many other ideas in religion and morality.
Knowledge is by default a non-absolute folk concept with the following general properties. When an explanation can be shown to be non-causative due to a more demonstrable and correct explanation, the original explanation is generally deemed incorrect. Science has become a more correct explanation of the existence of the 'self' and of the universe itself, than the idea of a soul and a god. The concept of a soul and a god are both incorrect, unless we include faith and assumption in our concept of knowledge.
It is popular to claim that science is flawed, and that this purported fact means that there is a god ("intelligent designer") and there is a soul. This is just anthropic bias. Even if our scientific models of physics and evolution are quite flawed (they are not), we are still left with the problem of our existence and with no reason to suppose that there is a soul and that there is a god without assumption.
There is no god, there is no soul. Get over it bitches.
