Abstract: I defend the historical definition of “function” originally given in my Language, Thought and Other Biological Categories (1984a). The definition was not offered in the spirit of conceptual analysis but is more akin to a theoretical definition of “function”. A major theme is that nonhistorical analyses of “function” fail to deal adequately with items that are not capable of performing their functions.
A Powerful Theory of Causation
Abstract: Hume thought that if you believed in powers, you believed in necessary connections in nature. He was then able to argue that there were none such because anything could follow anything else. But Hume wrong-footed his opponents. A power does not necessitate its manifestations: rather, it disposes towards them in a way that is less than necessary but more than purely contingent. In this paper a dispositional theory of causation is offered. Causes dispose towards their effects and often produce them. But a set of causes, even though they may succeed in producing an effect, cannot necessitate it since the effect could have been counteracted by some additional power. This would require a separation of our concepts of causal production and causal necessitation. The most conspicuous cases of causation are those where powers accumulate and pass a requisite threshold for an effect to occur. We develop a model for representing powers as constituent vectors within an n-dimensional quality space, where composition of causes appears as vector addition. Even our resultant vector, however, has to be understood as having dispositional force only. This model throws new light on causal modality and cases of prevention, causation by absence and probabilistic causation.
Properties as Processes
Summary: Sellars’ critics have, predominantly, studied single aspects of his work. This essay, on the other hand, is motivated by Sellars’ dictum that “analysis without synopsis is blind” (TWO 527). My intent is to give a synopsis of Sellars’ thought by focusing on the nominalist strands of his scheme. I shall try to draw the reader’s attention to the systematicity and overall coherence of Sellars’ work, since I think that any successful analysis of his writings must heed their systematic context. By presenting Sellars’ logical, semantic, epistemological and metaphysical arguments for the expendability of abstract entities in their systematic connection, I hope to promote both ‘full scope nominalism’ and ‘full scope Sellarsianism.’
Natural Selection as a Population-Level Causal Process
Abstract: Recent discussions in the philosophy of biology have brought into question some fundamental assumptions regarding evolutionary processes, natural selection in particular. Some authors argue that natural selection is nothing but a population-level, statistical consequence of lower-level events (Matthen and Ariew [2002]; Walsh et al. [2002]). On this view, natural selection itself does not involve forces. Other authors reject this purely statistical, population-level account for an individual-level, causal account of natural selection (Bouchard and Rosenberg [2004]). I argue that each of these positions is right in one way, but wrong in another; natural selection indeed takes place at the level of populations, but it is a causal process nonetheless.
Causation, Free Will, and Naturalism
This chapter addresses the worry that the existence of causal antecedents to your choices means that you are causally compelled to act as you do. It begins with the folk notion of cause, leads the reader through recent developments in the scientific understanding of causal concepts, and argues that those developments undermine the threat from causal antecedents. The discussion is then used as a model for a kind of naturalistic metaphysics that takes its lead from science, letting everyday concepts be shaped and transformed by scientific developments.
Aquinas
Publisher’s Note: Few philosophers or theologians exerted as much influence on the shape of Medieval thought as Thomas Aquinas. He ranks amongst the most famous of the Western philosophers and was responsible for almost single-handedly bringing the philosophy of Aristotle into harmony with Christianity. He was also one of the first philosophers to argue that philosophy and theology could support each other. The shape of metaphysics, theology, and Aristotelian thought today still bears the imprint of Aquinas work. In this extensive and deeply researched study, Eleonore Stump engages Aquinas across the full range of his philosophical writings. She examines Aquinas’ major works, Summa Theologiae and Summa Contra Gentiles and clearly assesses the vast range of Aquinas’ thought from his metaphysics, theology, philosophy of mind and epistemology to his views on free will, action, the soul and ethics, law and politics. She considers the influence of Aquinas’ thought on contemporary philosophy and why he should be still read today.
Knowledge of Arithmetic
Abstract: The goal of the research programme I describe in this article is a realist epistemology for arithmetic which respects arithmetic’s special epistemic status (the status usually described as a prioricity) yet accommodates naturalistic concerns by remaining funda- mentally empiricist. I argue that the central claims which would allow us to develop such an epistemology are (i) that arithmetical truths are known through an examination of our arithmetical concepts; (ii) that (at least our basic) arithmetical concepts are accurate mental representations of elements of the arithmetical structure of the inde- pendent world; (iii) that (ii) obtains in virtue of the normal functioning of our sensory apparatus. The first of these claims protects arithmetic’s special epistemic status relative, for example, to the laws of physics, the second preserves the independence of arithmetical truth, and the third ensures that we remain empiricists.
Models as mediating instruments
Summary: Morrison and Morgan argue for a view of models as ‘mediating instruments’ whose role in scientific theorising goes beyond applying theory. Models are partially independent of both theories and the world. This autonomy allows for a unified account of their role as instruments that allow for exploration of both theories and the world.
The Enduring Appeal of Natural Theological Arguments
Abstract: Natural theology is the branch of theology and philosophy that attempts to gain knowledge of God through non-revealed sources. In a narrower sense, natural theology is the discipline that presents rational arguments for the existence of God. Given that these arguments rarely directly persuade those who are not convinced by their conclusions, why do they enjoy an enduring appeal? This article examines two reasons for the continuing popularity of natural theological arguments: (i) they appeal to intuitions that humans robustly hold and that emerge early in cognitive development; (ii) they serve an argumen- tative function by presenting particular religious views as live options. I conclude with observations on the role of natural theology in contemporary analytic philosophy of religion.
The Trouble With Nominalism
Summary: Wetzel raises an important but underdiscussed argument for Platonism. We quantify over types (contrast with tokens) in sentences that we take to be true. This means we are, prima facie, committed to the existence of types. Wetzel considers various ‘nominalization’ strategies to get rid of type discourse and finds them all wanting. As a result, argues Wetzel, nominalism is untenable.
