What is metaphysics? Yet again. The difference between the two is the difference between the different grounds of being in each. The ground of being in the Tao Te Ching is the Tao, the undifferentiated unity which is the natural state of existence before humans get involved. For science, it is objective reality, which represents the multiplicity of concrete phenomena that would make up the universe even if there was no consciousness.

But from the point of view of a kind of Kantianism--particularly Schopenhauer's--these two are consistent. At least, they're consistent if science's objective reality is not taken as the ground of being. My guess is that this is quite a common stance even among scientific people. It was something like Kant's view, and Kant himself was an astronomer and cosmologist who claimed never to be denying the reality of empirical reality (science's objective reality).
You know the story: we perceive and model the world in the way we do owing to the way that we
must do according to our perceptual and conceptual faculties. We never get beyond that to see the world in itself, the ground of being. What we have then, and what we study scientifically, is empirical reality, i.e., real and objective but bound reciprocally with human beings. (Whether this is coherent or not is another story).
It was Schopenhauer who took it a step further and asserted positively that the thing in itself, that which is beyond human perception and concepts, is an undifferentiated unity. He might have been encouraged in this by his reading of Eastern philosophy.
Although they seem contradictory, I didn't feel any conflict in using both ways of understanding. I could hold them both in my mind at the same time. That's when I started to think about the fact that they weren't true or false. Sometimes it made sense for me to think in one way and at other times the other. That's what made it clear that neither was true or false. — T Clark
So it seems to me that it doesn't necessarily follow from one's ability to hold both positions at the same time that they are neither true nor false. They might be doing different things, and are true in their own ways, meaning at their own levels of description or within their own scope. In a similar way, you can think of a painting as a certain configuration of pigments, and you can describe it that way in great detail, but you can also think of it as a moving portrait or beautiful scene or whatever. Different levels or modes of description, both having true or false statements. (I suspect you're an emotivist who doesn't believe artistic judgments have truth value, but I don't think that's relevant here; maybe I should have thought of a better example).
