There is a broad consensus that Aristotle introduced the concept of matter in order to develop a consistent account of substantial change. However, it is disputed which role matter fulfills in substantial change. According to the traditional interpretation, matter persists while taking on or losing a substantial form. According to a rival interpretation, matter does not persist in substantial change; instead, it is an entity from which a new substance can emerge and which ceases to exist in this process. In my view, both interpretations are problematic in the light of Aristotle’s broader ontological project and are at odds with the way Aristotle describes the substantial generation of living beings. On the basis of Aristotle’s biological theory, I will suggest that Aristotelian matter is a continuant in substantial generation, but does not satisfy the common criteria for persistence that apply to individual substances.

Western metaphysics is based on the opposition between reality and appearance. This construction essentially rests on a visual model, or more exactly on some staging of what visual experience is.
I am going to question the basis of this metaphysics, by taking into account the reality of appearances and reflecting on their various uses, in particular artistic ones. This path will be taken in the first place by shifting the focus of philosophical analysis from visual to acoustic models. Thus, I will envisage a realism of echoes, as opposed to the metaphysics of shadows.

Biography:

Jocelyn Benoist, born in 1968, is Professor at the university Paris 1 Panthéon-Sorbonne, where he teaches Contemporary Philosophy, and currently a member of the ‘Institut Universitaire de France’. He has dedicated his early work to phenomenology and the bridges between phenomenology and early Analytic philosophy. For some time he was the Director of the Husserl Archive of Paris at the Ecole Normale Supérieure. Then, he developed a personal investigation into the meaning of realism in philosophy. He has published many books, including recently: Toward a Contextual Realism, H.U.P., 2021, and Von der Phänomenologie zum Realismus, Mohr Siebeck, 2022.

In this paper, I explore the role that metaphor plays in the development of new scientific models. My goal is to illustrate metaphor’s fecundity in this regard, the way in which it extends our understanding in surprisingly diverse ways. As Mary Hesse put this point, “it is precisely in its extension that the fruitfulness of the model may lie” (1980, 114).

The particular focus of my paper is on the history of what John Haugeland called mind design: the use of mechanical models to reverse-engineer how minds work (1997, 1). My history focuses on two such models: the clockwork model and the computer model. In each case, I show how a metaphorical understanding of the model led to conceptual innovation in two distinct ways. First, it provided an interpretive frame that guided new research by offering an abstract, hypothesized structure to be later filled in by empirical research (Camp 2020). Second, it provided a concrete exemplar to contrast with human minds (Daston 1994). For instance, while on the one hand Descartes invoked the clockwork model to explain how color vision works (Adams 2015), he also invoked it as a vivid illustration of how human reasoning does not work (Riskin 2016).

It is this second source of conceptual innovation that is the real core of the paper; it reveals what I call the dialectic of mind design. This dialectic is especially evident in our tendency to redefine what it is to be human in response to new technological developments. For instance, it is evident when we take something that was previously assumed to be paradigmatic of mental acuity, such as the ability to play chess, and redefine it as something merely mechanical (Ensmenger 2012). But it is equally well evident when we take something that was previously taken to be mechanical—such as color vision—and redefine it as paradigmatically mental (Chalmers 1997; cf. Adams and Browning 2020). The concept of mindedness is, in this sense, a constantly moving goalpost that is perennially being redefined in response to new technological developments.
