10 ideas
| 7017 | The reductionist programme dispenses with levels of reality [Heil] |
| Full Idea: The reductionist programme dispenses with levels of reality. | |
| From: John Heil (From an Ontological Point of View [2003], 04.3) | |
| A reaction: Fodor, for example, claims that certain causal laws only operate at high levels of reality. I agree with Heil's idea - the notion that there are different realities around here that don't connect properly to one another is philosopher's madness. |
| 18539 | Our categories lack the neat arrangement needed for reduction [Heil] |
| Full Idea: Categories we use to describe and explain our universe do not line up in the neat way reductive schemes require. | |
| From: John Heil (The Universe as We Find It [2012], 13.2) | |
| A reaction: He takes reduction to be largely a relation between our categories, rather than between entities, so he is bound to get this result. He may be right. |
| 4616 | A higher level is 'supervenient' if it is determined by lower levels, but has its own natural laws [Heil] |
| Full Idea: 'Supervenience' means lower-level objects and properties suffice for the higher level ones, but the higher level is distinct from its ground, which is reflected in the higher level being governed by distinct laws of nature. | |
| From: John Heil (Philosophy of Mind [1998], Ch.6) | |
| A reaction: A nice summary of Davidson's idea. It feels wrong to me. Can I create some 'new laws of nature' by combining things novelly in a laboratory so that a supervenient state emerges. Sounds silly to me. Must we invoke God to achieve this? |
| 7003 | There are levels of organisation, complexity, description and explanation, but not of reality [Heil] |
| Full Idea: We should accept levels of organisation, levels of complexity, levels of description, and levels of explanation, but not the levels of reality favoured by many anti-reductionists. The world is then ontologically, but not analytically, reductive. | |
| From: John Heil (From an Ontological Point of View [2003], Intro) | |
| A reaction: This sounds right to me. The crunch questions seem to be whether the boundaries at higher levels of organisation exist lower down, and whether the causal laws of the higher levels can be translated without remainder into lower level laws. |
| 7045 | Realism says some of our concepts 'cut nature at the joints' [Heil] |
| Full Idea: Realism is sometimes said to involve a commitment to the idea that certain of our concepts, those with respect to which we are realists, 'carve reality at the joints'. | |
| From: John Heil (From an Ontological Point of View [2003], 14.11) | |
| A reaction: Clearly not all concepts cut nature at the joints (e.g. we have concepts of things we know to be imaginary). Personally I am committed to this view of realism. I try very hard to use concepts that cut accurately; why shouldn't I sometimes succeed? |
| 7065 | Anti-realists who reduce reality to language must explain the existence of language [Heil] |
| Full Idea: Anti-realist philosophers, and those who hope to reduce metaphysics to (or replace it with) the philosophy of language, owe the rest of us an account of the ontology of language. | |
| From: John Heil (From an Ontological Point of View [2003], 20.6) | |
| A reaction: A nice turning-the-tables question. In all accounts of relativism, x is usually said to be relative to y. You haven't got proper relativism if you haven't relativised both x and y. But relativised them to what? Nietzsche's 'perspectivism' (Idea 4420)? |
| 18505 | Fundamental ontology aims at the preconditions for any true theory [Heil] |
| Full Idea: Fundamental ontology is in the business of telling us what the universe must be like if any theory is true. | |
| From: John Heil (The Universe as We Find It [2012], 01.1) | |
| A reaction: Heil is good at stating simple ideas simply. This seems to be a bold claim, but I think I agree with it. |
| 18499 | Our quantifications only reveal the truths we accept; the ontology and truthmakers are another matter [Heil] |
| Full Idea: Looking at what you quantify over reveals, at most, truths to which you are committed. What the ontology is, what the truthmakers are for these truths, is another matter, one tackled, if at all, only in the pursuit of fundamental physics. | |
| From: John Heil (The Universe as We Find It [2012], 08.08) | |
| A reaction: Exactly right. Nouns don't guarantee objects, verbs don't guarantee processes. If you want to know my ontological commitments, ask me about them! Don't infer them from the sentences I hold true, because they need interpreting. |
| 18512 | Ontology aims to give the fundamental categories of being [Heil] |
| Full Idea: The task of ontology is to spell out the fundamental categories of being. | |
| From: John Heil (The Universe as We Find It [2012], 02.5) | |
| A reaction: This is the aspiration of 'pure' metaphysics, which I don't quite believe in. There is too much convention involved, on the one hand, and physics on the other. |
| 7020 | Concepts don't carve up the world, which has endless overlooked or ignored divisions [Heil] |
| Full Idea: Concepts do not 'carve up' the world; the world already contains endless divisions, most of which we remain oblivious to or ignore. | |
| From: John Heil (From an Ontological Point of View [2003], 05.3) | |
| A reaction: Concepts could still carve up the world, without ever aspiring to do a complete job. We carve up the aspects that interest us, but the majority of the carving is in response to natural divisions, not whimsical conventions. |
