    Two Concepts of Emergence

    Timothy O'Connor (Indiana) gives a talk for the Power Structuralism in Ancient Ontologies podcast series. Abstract: The correlated terms "emergence" and "reduction" are used in several ways in contemporary discussions ranging from complex systems theory to philosophy of mind, a fact that engenders confusion or talking at cross purposes. I try to bring greater clarity to this discussion by reflecting on John Conway's cellular automaton The Game of Life and simple variations on it. We may think of such variants as toy models of our own world that, owing to their simplicity, enable us to see quite clearly, in general terms, two importantly distinct ways (“weak” and “strong”) in which organized macroscopic phenomena might emerge from underlying microphysical processes. Strong emergence is of greater significance to metaphysics and philosophy of mind; it is also commonly deemed implausible. I close by suggesting that typical reasons for this evidential judgement are unconvincing.

    Processes and Powers

    John Dupré (Exeter) gives a talk for the Power Structuralism in Ancient Ontologies podcast series Abstract: This talk will explore the implications for a metaphysics of powers of the replacement of a substance ontology with a process ontology. I take a process to be an entity that must be active in some way to exist and I argue that processes are more fundamental than things: things are temporary and partial stabilisations in a flux of process. Can the activities that sustain processes be understood as the exercise of powers? Can the interactions between processes be treated similarly as the exercises of powers by processes?

    Powers: Necessity and Neighbourhoods

    Neil Williams (Buffalo University) gives a talk for the Power Structuralism in Ancient Ontologies podcast series Abstract; The typical understanding of powers—according to which they have their effects necessarily—has recently come under attack. The threat of imagined counterfactual scenarios (wherein the power is exercised but the characteristic manifestation does not ensue) has led some to question the traditional picture, and prompted others to give it up entirely. But this defection has been too hasty: that exercising powers produce their manifestations necessarily ranks highly among the most attractive features of the powers metaphysic, and should not be discarded lightly. Moreover, the arguments against necessity are founded upon assumptions that the friend of powers is at liberty to reject. I show how the anti-necessitarian arguments can be avoided, and thus how necessity can be restored.

    Causal Production as Interaction: a Causal Account of Persistence and Grounding

    Rögnvaldur Ingthorsson (Lund University) gives a talk for the Power Structuralism in Ancient Ontologies podcast series Abstract: In this talk I will elaborate on the naturalist theory of causation that I first presented in ‘Causal Production as Interaction’ (2002). In the course of presenting the view I will elucidate in what sense the account (i) presents causation as a necessary process of production without appeal to ceteris paribus clauses, (ii) explains the connection between causation and counterfactuals without appeal to a possible worlds ontology, (iii) does not suffer from the problem of action at a temporal distance, (iv) can exclude the possibility of interference and prevention, (v) is compatible with the way the natural sciences describe material reality (within the framework of classical science), and indeed explains why material reality—as described by science—is a causal reality. I will also indicate, more sketchily, how this causal account allows us to think of the persistence of compound entities as being a thoroughly causal affair, and thus provide a causal account of composition and grounding. Finally, I will discuss whether account depicts persistent compounds as both substances and processes.

    Doing Away With Dispositions: Towards a Law-Based Account of Modality in Science

    Stephen French (Leeds) gives a talk for the Power Structuralism in Ancient Ontologies series. Abstract: 'Recent defences of dispositionalism and powers based accounts have appealed to the way properties such as charge and spin are treated in physics. However, I shall argue that on closer analysis, modern physics does not supply the level of support that is typically adduced. Adjusting these accounts to bring them more into line with the way physics treats such properties takes them closer to certain structuralist views and I shall explore the - sometimes wafer thin - differences between these alternative approaches to properties. In conclusion I shall suggest that adopting an appropriate stance towards 'reading' theories in physics does away with dispositions and powers as seated in fundamental objects in favour of modally informed structure.'

    Quidditism and Modal Methodology

    Alastair Wilson, Birmingham, gives a talk for the Power Structuralism in Ancient Ontologies series Abstract: Jonathan Schaffer has recently defended the doctrine of quidditism against an epistemological challenge, claiming that the challenge amounts to nothing more than ‘external-world scepticism writ small’. I disagree with this assessment. The cases are significantly disanalogous, and quiddistic scepticism is much harder to avoid than external-world scepticism. Ultimately, the epistemological challenge is indecisive: quidditists can live with the sceptical conclusion. But there is a stronger anti-quidditist argument in the vicinity. Following John Hawthorne, I show how the epistemological challenge can be reformulated as an argument from theoretical parsimony. I argue that whether the parsimony argument is decisive depends on wider issues in the metaphysics of modality: different accounts of modality yield different verdicts about parsimony. The upshot is that we cannot expect to make progress in the quidditism debate while remaining neutral on the nature of modality.

    The Fundamentality of the Familiar

    Nick Jones, University of Birmingham, gives a talk in which he appeal to an examination of the explanatory role of ordinary macroscopic objects to argue that some of them are metaphysically fundamental.

    Aristotle's Dynamics in Physics VII 5: the Importance of Being Conditional

    Henry Mendell (California State) gives a talk for the Power Structualism in Ancient Ontologies series Abstract: Historians in the twentieth century argued about whether Aristotle presents a general theory of dynamics in Physics VII 5 or merely presents examples from ordinary experience, which he then applies abstractly to arguments about the unmoved mover and general issues about the balance of elements in the sublunary realm. Recently the pendulum of opinion has swayed towards taking Aristotle's account more robustly as a general theory of dynamics, but more can be said. I shall argue that one reason why the debate arose was because both sides have seen the examples in the context of Greek style mathematics, where we expect generalized principles and theorems, often couched in a modern, anachronistic representation. I suggest that the dynamics come from an older mathematical tradition, which we associate with Babylon and Egypt and which, I believe, was ordinary Greek mathematical practice even in the fourth century BCE. Mathematicians present their work as problems, given such and such, here is how to calculate such and such. It is also characteristic of a problem and the procedure for its solution that actual numbers are used. We find both in Aristotle's presentation. Aristotle's rules are stated in the form of conditionals with actual numbers. So the rules have the form: if mover A moves moved B in time D over distance G, then one may vary A, B, D, and G in the following ways, e.g. 1/2 B over 2 D. The initial conditions in the antecedent, in effect, implicitly set the parameters for the variations in the consequent, as given by example. In this way, the procedures are general over all dynamic problems set up conditionally. Aristotle proceeds to set boundaries on the consequent. However, the text that we have at this point, regardless of variations in the textual tradition, is mathematically bizarre. Whether this is Aristotle's error or an early error in the transmission of the text, the anomaly contributes to the evidence that Aristotle is actually borrowing his examples from an earlier work on dynamics that was written in the problem tradition.
