The electrons go together, and neither goes with the cow.” -- Sider — J
The only reason electron-plus-cow seems like a bad way of carving reality is context--not any absolute ontological structure. — T Clark
Now I want to depart from Sider on one point. (And I should emphasize that much of the above is my own interpretation of Sider.) I’m not convinced that “reality’s fundamental structure” is the best way to talk about what Sider wants to talk about. I don’t know how fundamental the various reference magnets may be, or whether it’s necessary to drag in “reality” (one of those very terms whose ambiguity causes so much trouble). — J
I think there are natural kinds, but they are natural human kinds. They are manifestations of our human nature and, beyond that of our own specific personal natures. — T Clark
With all of these quotes, we're focusing on a key point for Sider and the idea of reference magnetism. I believe it's a somewhat open question. If we could adopt the ultra-objective "view from nowhere/anywhere," would the same reference magnets exert their influence? Is that what we require in order to talk about "reality's fundamental structure"? Sider declares himself to be an ontological realist; he thinks the answ
er is Yes. Yet, in his discussion of the electrons and the cow, he never claims that a cow-plus-electron grouping is impossible, or incoherent, or even wrong according to some principle. He calls it "bizarre," and says that "the three objects
should be [my itals] divided into two groups" as custom would dictate.
When I ended the OP by saying that we needed to do a lot more work on concepts like "right sort of basis," this is the kind of situation I had in mind. In Sider's favor: There is surely such a thing as a non-bizarre interpretation, in which the two electrons do "go together"; he isn't making that up. Your suggestion is that bizarre vs. ordinary is a referendum on human uses and contexts. And that too seems plausible. The question, I think, is whether we can argue that our human uses are themselves not arbitrary, but reflect actual ontological structure of some kind. I was jibbing at "fundamental," but there may be other kinds of structure which are to some extent invariant, though depending upon the life-world of humans for their perceptibility. Arguably, that's enough to satisfy Sider; he could reply that these kinds of structure are all that logic and metaphysics means to deal with. Quantification isn't a statement about ultimate reality, or even an endorsement that there must be such a thing.
in Ontologese, quantifiers are stipulated to carve at the joints. In other words, they are attracted by the correct, eligible reference magnets.
— J
Can you give an example of this? — T Clark
First, a little more elaboration. This gives us the context:
Suppose . . . that there exist, in the fundamental sense, nothing but sub-atomic particles. Given such a sparse ontology, the most plausible view about natural language quantifiers might be that they do not carve at the joints. The best metaphysical semantics of an ordinary sentence like 'There is a table' might be . . . a tolerant semantics, which interprets it as making the true claim that there exist sub-atomic particles appropriately arranged. The English 'there is', according to such a semantics, would not express fundamental quantification. . . So even if there is a joint-carving sort of quantification, the quantifiers of ordinary language might not carve at the joints. — Sider, 171-72.
Thus, Sider's E* is introduced as the quantifier that does carve at the joints -- on this example, it would refer to sub-atomic particles.
We're talking here about the "big" term "exist". Let's move to a less austere term: "happiness". Philosopher A maintains that happiness refers to a state that's measured in terms of pleasures and pains. Thus, it's possible, though unusual, for a person to fail to seek their own happiness, due to some defect of the psyche. Philosopher B maintains that happiness is best understood as that state which all people do in fact seek, since we are egoistic hedonists, and cannot fail to act in our own behalf.
This is a classic dispute about terms. A and B can go on (and on) to argue out their respective uses of "happiness" (perhaps joined by Philosopher C, who will maintain that happiness has nothing to do with pleasures and pains). Or . . . they can pose the Siderian question, "Is there something here that carves at the joints, ethically or psychologically? Is there a way of putting aside the divergent use of terms and discovering some actual structural item to which we can agree to refer?" With a term like "happiness," there are those who would claim that there is no such item. But I think there is. We can point out that there is such a thing as experiencing pleasure. Likewise, we might agree that there is such a thing as attempting to act in one's own best interests. These are reference magnets; they are "in the vicinity" of the term "happiness," and exert pressure on different philosophers to make the identification with "happiness." But we can resist that pressure, and instead decide to talk about the references, not the terms. Sider suggests this is best done not by stipulating one use of "happiness" for purposes of the discussion, but by coining or adapting a new term that is stipulated to carve at whatever joint may be available to be carved at.
Sider warns us, "Whether the introduction of Ontologese succeeds depends on the facts, on whether there is a joint-carving sort of quantification." He compares this with a proposal to introduce the term "dirt" as meaning "that element of the periodic table that allows trees to grow, etc." This isn't going to work, because there is no such element, and presumably no other reference magnet in the vicinity that is joint-carving.
The problem with that for me is, again sticking with metaphysics as the example, I need the idea as formulated in my understanding of philosophy. The way I’ve dealt with that in discussions that I started is to specify in the OP exactly the definition of metaphysics I want to use for the purposes of that particular thread. As I noted, it’s often a struggle to keep other posters on that path. — T Clark
I sympathize, and I think Sider has this sort of thing in mind. Is there a way to bracket your use of "metaphysics," so to speak, and instead specify the (joint-carving) way in which you use that term? It could be set out not as a definition of 'metaphysics', but as an interesting conceptual or structural category you've noticed. I dunno . . . people might still want to argue terms.
