Proposes a new way of understanding the nature of metaphysics, focusing on nonreductionist emergence theory, both in ancient and modern philosophy, as well as in contemporary philosophy of science.

In recent years, many philosophers of science have attempted to articulate a theory of non-epistemic emergence that is compatible with mechanistic explanation and incompatible with reductionism. The 2005 account of Fred C. Boogerd et al. has been particularly influential. They argued that a systemic property was emergent if it could not be predicted from the behaviour of less complex systems. Here, I argue that Boogerd et al.'s attempt to ground emergence in complexity guarantees that we will see emergence, but at (...) the cost of rendering it either trivial or epistemic. There are three basic problems. First, neither the measures of complexity explicitly mentioned by Boogerd et al. nor the most popular measures in the literature can do the practical and theoretical work that they assign to complexity. Second, I argue that while the success of their view depends on restricting the base of information available to the reductionist, this cannot be done in a way that is metaphysically neutral with respect to emer..

This paper examines the metaphysical status of the fact-value entanglement. According to Hilary Putnam, among others, this is a major theme in both classical and recent pragmatism, but its relevance obviously extends beyond pragmatism scholarship. The pragmatic naturalist must make sense of the entanglement thesis within a broadly non-reductively naturalist account of reality. Two rival options for such metaphysics are discussed: values may be claimed to emerge from facts (or normativity from factuality), or fact and value may be considered continuous. (...) Thus, pragmatic naturalism about fact and value may be based on either emergentism or Peircean synechism. This is a crucial tension not only in pragmatist philosophy of value but in pragmatically naturalist metaphysics generally. (shrink)

A prominent objection to supervenience physicalism is that a definition of physicalism in terms of supervenience allows for physicalism to be compatible with nonphysicalist outlooks, such as certain forms of emergentism. I take as my starting point a recent defense of supervenience physicalism from this objection. According to this line of thought, the subvenient base for emergent properties cannot be said to be purely physical; rather, it is “polluted” with emergent features in virtue of necessarily giving rise to them. Thus, (...) if emergentism is true, it is false that everything supervenes on physical properties. I argue that this gives way to a new challenge for supervenience physicalism. The challenge, roughly, is to distinguish the emergentist’s “polluted” base from a physical supervenience base; that is, to give conditions under which the subvenient base is not “polluted” by supervenient properties. The problem, I argue, is that it is hard to see how this can be done without collapsing supervenience physicalism into alternative approaches to physicalism. I thus argue that if the present defense of supervenience physicalism succeeds in defending the adequacy of a supervenience-based definition of physicalism, it does so by compromising its uniqueness.

Philosophical accounts of emergence have been explicated in terms of logical relationships between statements (derivation) or static properties (function and realization). Jaegwon Kim is a modern proponent. A property is emergent if it is not explainable by (or reducible to) the properties of lower level components. This approach, I will argue, is unable to make sense of the kinds of emergence that are widespread in scientific explanations of complex systems. The standard philosophical notion of emergence posits the wrong dichotomies, confuses (...) compositional physicalism with explanatory physicalism, and is unable to represent the type of dynamic processes (self-organizing feedback) that both generate emergent properties and express downward causation.

The tradition of pragmatism has, especially since Dewey, been characterized by a commitment to nonreductive naturalism. The notion of emergence, popular in the early decades of the twentieth century and currently re-emerging as a central concept in metaphysics and the philosophy of mind, may be useful in explicating that commitment. The present paper discusses the issue of the reality of emergent properties, drawing particular attention to a pragmatic way of approaching this issue. The reality of emergents can be defended as (...) a pragmatically-useful ontological commitment; hence, pragmatism can be employed as a tool in the debate over the structure and reality of emergence. This strategy of justifying ontological commitments is examined through historical and systematic discussions of the pragmatist tradition. It turns out, among other things, that while classical pragmatists did not specify any technical notion of emergence in the contemporary sense, their non-reductively naturalist views are relevant to the more recent emergence discussions -- especially because they rejected the metaphysical realism typical of today’s ontologically-oriented emergence theories.

John Searle's The Rediscovery of the Min is a sustained attempt to locate the mind and the mental firmly in the realm of the physical. Consciousness ,claims Searle, is just an ordinary biological feature of the world ... More specifically,``[t]he mental state of consciousness is just an ordinary biological, that is, physical featureof the brain''. Searle is adamant: ``Consciousness,to repeat, is a natural biological phenomenon''.

I develop a variant of the constraint interpretation of the emergence of purely physical (non-biological) entities, focusing on the principle of the non-derivability of actual physical states from possible physical states (physical laws) alone. While this is a necessary condition for any account of emergence, it is not sufficient, for it becomes trivial if not extended to types of constraint that specifically constitute physical entities, namely, those that individuate and differentiate them. Because physical organizations with these features are in fact (...) interdependent sets of such constraints, and because such constraints on physical laws cannot themselves be derived from physical laws, physical organization is emergent. These two complementary types of constraint are components of a complete non-reductive physicalism, comprising a non-reductive materialism and a non-reductive formalism. (shrink)

Tim Crane's ‘Cosmic Hermeneutics vs. Emergence: The Challenge of the Explanatory Gap’ claims that non‐reductive physicalism must either close the explanatory gap, addressing the challenge famously posed by Levine's argument, or become identical to emergentism. Since no way to close the gap is available, the result is that there can be no interesting philosophical position intermediate between physicalism and emergentism. This chapter argues that if we look at the relation between physicalism and emergentism from the vantage point of reduction, Crane's (...) analysis is rather persuasive. However, if we switch from reduction to causality, its conclusions appear more disputable. In particular, if we shift from ‘novelty and explanation’ to ‘novelty and causality’ as key features of emergent properties, we may introduce a distinction between two kinds of emergentism (moderate and radical) based on their attitude towards the causal inheritance principle. If the causal inheritance principle is accepted (some versions of) moderate emergentism may be considered as non‐trivial forms of non‐reductive physicalism. (shrink)
