Does he ever fully explain what he means by this? This reads super vaguely. — Heister Eggcart
I think he means that there's no other realm, no supernatural realm, that the world exists by itself...
The broader ontology typically associated with atheism is naturalism—there is only one world, the natural world, exhibiting patterns we call the “laws of nature,” and which is discoverable by the methods of science and empirical investigation. There is no separate realm of the supernatural, spiritual, or divine; nor is there any cosmic teleology or transcendent purpose inherent in the nature of the universe or in human life. “Life” and “consciousness” do not denote essences distinct from matter; they are ways of talking about phenomena that emerge from the interplay of extraordinarily complex systems. Purpose and meaning in life arise through fundamentally human acts of creation, rather than being derived from anything outside ourselves. Naturalism is a philosophy of unity and patterns, describing all of reality as a seamless web
Yet, the same man who just wrote the above is also vehemently against the many religious traditions that, unfortunately for him, tell a similar story in a multitude of different ways! — Heister Eggcart
I think this might be because he thinks that it goes against his second point...
-There are many ways of talking about the world.
-All good ways of talking must be consistent with one another and with the world.
-Our purposes in the moment determine the best way of talking.
Though, does Carroll provide a measure for what constitutes greater and lesser degrees of usefulness? — Heister Eggcart
I'm not sure, I still haven't reached very far but this is what he says...
I’m going to argue for a different view: our fundamental ontology, the best way we have of talking about the world at the deepest level, is extremely sparse. But many concepts that are part of non-fundamental ways we have of talking about the world—useful ideas describing higher-level, macroscopic reality—deserve to be called “real.” The key word there is “useful.” There are certainly non-useful ways of talking about the world. In scientific contexts, we refer to such non-useful ways as “wrong” or “false.” A way of talking isn’t just a list of concepts; it will generally include a set of rules for using them, and relationships among them. Every scientific theory is a way of talking about the world... Today, we would say that Kepler’s theory is fairly useful in certain circumstances, but it’s not as useful as Newton’s, which in turn isn’t as broadly useful as Einstein’s general theory of relativity
What we’re seeing is a manifestation of the layered nature of our descriptions of reality. At the deepest level we currently know about, the basic notions are things like “spacetime,” “quantum fields,” “equations of motion,” and “interactions.” No causes, whether material, formal, efficient, or final. But there are levels on top of that, where the vocabulary changes. Indeed, it’s possible to recover pieces of Aristotle’s physics quantitatively, as limits of Newtonian mechanics in an appropriate regime, where dissipation and friction are central. (Coffee cups do come to a stop, after all.) In the same way, it’s possible to understand why it’s so useful to refer to causes and effects in our everyday experience, even if they’re not present in the underlying equations. There are many different useful stories we have to tell about reality to get along in the world.
So, I'm wondering who decides that it is only useful to consider causes "real" at a higher level and not at the fundamental level too? As I said, I think that it is useful to Mr. Carroll because he thinks it fits his atheist/naturalist view better, but if someone does not have that view, then it might not be useful to get rid of causes at the fundamental level. If usefulness determines the reality of things, then doesn't it follow that different people who find different things useful (in order "to get along in the world") will talk about the world differently? After all, talking about causes at the fundamental level, does not make predictions less accurate. Am I wrong???
