I would like to challenge you to try to think from first principles. This means you are searching for an explanation for your beliefs which is the most comprehensive and cohesive with known facts.
Thinking from first principles will eliminate dualism of any kind. While there have been dualisms proposed by the great Thinkers, Philosophy and Science can never ever be satisfied with an unbridgeable dualism.
For example, why should there be an “is/ought” distinction? Are their ANY cases in which we fell confident that this does not apply? Are their any things in this universe that have a purpose as a matter of undeniable fact? What is the purpose of bird’s wings? If I say that “A bird OUGHT to be able to fly.”, am I committing the naturalistic fallacy? What if I say that “Humans ought to talk to each other and think about things.”, is THAT justified any less than something I say about birds? I don;t think so.
Not only do wings have a purpose for birds, but birds also have an ecological purpose. They perform a function for the biosphere. What’s so mystical about that? There’s nothing supernatural or non-physical about purpose or function. Perhaps you might think that there is, but the fact that you think that way has a rather nifty explanation which is far more comprehensive and cohesive than the explanation you will give for why your life has purpose.
Dualism is the mind-killer. Face your dualism and let is pass over you. When it is gone, only the Arkhe will remain.
Long ago we thought there was two kinds of matter: celestial and terrestrial. But then we found they were the Same. Later on we had a dualism of matter and energy; those also were the Same.
What about Matter/Energy and Space and Time, are they not totally different?. Later on, we found out that is the Same as well.
What about the difference between Physical reality and Information, are they not totally different? Guess what? Later on, we found out that information is a physical phenomenon. (No kidding! Look it up.)
So if you come up with some tiny thing you think is so special that it could never ever be the Same as something else. I will laugh at you.
Any statement of the form “There are only two types of things: x and everything else.” is by definition unwarranted. Its very form violates the conditions of possible knowledge. This is because all explanation as such must subsume the explanandum under a genus as a new species with a difference from other species.
Formerly light was essentially the field of visibility and on the other hand there had recently been discovered “radiation”. One was visible and the other not; two things could not seem to be more different, could they? But in due course science explained radiation. How? Simple, we found that it was actually a form of light; invisible light, but light none the less. Now are you going to accept an argument that light qua light must be visible? In a very common sense way “light” is visible by definition, but science is not limited by common sense usage of any term. What physics has done with “light”, Philosophy must do with “consciousness” and “ethics”. Ethics is not necessarily ethical, and consciousness is not necessarily conscious.
