Perceptual systems and realism

Constructivism undermines realism by arguing that experience is mediated by concepts, and that there is no direct way to examine those aspects of objects that belong to them independently of our conceptualizations; perception is theory-laden. To defend realism one has to show first that perception relates us directly with the world without any intermediary conceptual framework. The result of this direct link is the nonconceptual content of experience. Second, one has to show that part of the nonconceptual content extracted from the environment correctly represents features of mind independent objects. With regard to the first condition, I have argued elsewhere that a part of visual processing, which I call “perception,” is theory-neutral and nonconceptual. In this paper, facing the second demand, I argue that a part of the nonconceptual content of perception presents properties that are the properties of mind independent objects. I claim first that nonconceptual content is the appropriate level of analysis of the issue of realism since it avoids the main problems besetting various types of analysis of the issue at the level of beliefs about the world. Then I claim that a subset of the nonconceptual content presents features of objects in the environment as they really are. This paper was mostly written when I was a fellow at the Center of Philosophy of Science in the University of Pittsburgh during the Spring Semester of 2005–2006. A draft of this paper was presented both at the Center’s colloquium and at one of the informal discussion meetings of the fellows. I have very much benefited from the discussion that followed the presentation of the paper and so I would like to thank Gabriele de Anna, Carla Fehr, Malcolm Forster, Lilly Gurova, Nikolay Milkov, and Wang Wei. I am especially indebted to the director of the Center Professor John Norton whose astute comments made me think hard about the issues discussed in the paper. Several of my arguments in Sect. 4 are the result of John’s concerns with the earlier draft of the paper. I would also like to thank the two anonymous reviewers for helping me clarify several points in the paper. Thanks to them (especially the second one) the paper is considerably better than it would have been without them.

An earlier version of this paper has been read at a conference on Mental Causation which was held on March 12–14, 1990, at the Center for Interdisciplinary Research (ZiF), University of Bielefeld, as an integral part of the work of the research group Mind and Brain. I am very grateful to ZiF for the financial support that made it possible for me to take part in the research group. Thanks also to the organizers of the conference Peter Bieri and Jaegwon Kim.     

Is space-time discrete or continuous? — An empirical question

In this paper I present the Discrete Space-Time Thesis, in a way which enables me to defend it against various well-known objections, and which extends to the discrete versions of Special and General Relativity with only minor difficulties. The point of this presentation is not to convince readers that space-time really is discrete but rather to convince them that we do not yet know whether or not it is. Having argued that it is an open question whether or not space-time is discrete, I then turn to some possible empirical evidence, which we do not yet have. This evidence is based on some slight differences between commonly occurring differential equations and their discrete analogs.I would like to express my thanks to John McKie with whom I have had several inspiring conversations about discrete space. I would also like to thank the audience of a paper on this topic which I read in October 1991 at the College Park campus of the University of Maryland. Finally I would like to thank the referees ofSynthese for their comments. One of them, in particular, should be thanked especially for help in improving Appendix Two.

I must also thank two anonymous referees, who were most helpful on both specific and general points, and Axel Boldt, who helped with the German.     

Empathy and the aesthetic: Why does art still move us?

In this article I will argue for the affective-motivation (background affective attitude or orientation) hypothesis that incubates the aesthetic experience and sets the deep frame of our engagement with art. For this, I look at these microgenetic—early passages of (a) affective perception as mapped into the early emergence of tertiary qualities that underlie a sensorimotor synchronization—a coupling of action, emotion and perception via mirroring that result in dynamic embodied anticipatory control and a feeling of proximity/connectedness and (b) developmental passages that are characterized by spatiotemporal coordination and proximity of the self-other/interactive object and thus structure intentionality, shape experience, in an engaging world of action potentialities forming a background affective attitude. As I will argue these qualitative emergent layers provide the minimal for the aesthetic and the ‘feeling into’ empathy, or their phenomenological counterparts enable engaged, embodied perception and imagination underlying expressive symbolic communication in interpersonal settings but also for the possibility of art. These layers have an ‘echoing’ effect (pre-attentive) when we let ourselves to be ‘moved’ from within by art. The underlying mechanism could be found in the mirroring interface of the upcoming bottom-up and feeding forward anticipatory/predictive (top-down) function of the ‘embodied action’ representations that are affective, imitative and grounded in the body-affective matrix—carrying experiential affordances and keeping the intersubjective ties between spectator and beheld/object. Given the asymmetry on action tendency between them that affords the ‘subordination of the goal-directed action’ into to the means of the action’s unfolding, aesthetic experiences can go deeply back reconstructing the first level of emerging consciousness where both the aesthetic and ethic became actualities. This could be by itself deeply rewarding, amplifying the experience to the ‘edge’. This is a ‘hot’ cognition self-restructuring related to morality when facing the sufferings—so there might be something special bout art and negative emotions in relation to empathy.     

Merleau-Ponty and Carroll on the Power of Movies

Movies have a striking aesthetic power: they can draw us in and induce a peculiar mode of involvement in their images – they absorb us. While absorbed in a movie, we lose track both of the passage of time and of the fact that we are sitting in a dark room with other people watching the play of light upon a screen. What is the source of the power of movies? Noël Carroll, who cites Maurice Merleau-Ponty as an influence on his account of the power of movies, agrees with Merleau-Ponty that our perceptual experience of movies draws on many of the capacities at work in our perceptual experience of everyday situations. Yet Merleau-Ponty’s account of perception shows that Carroll’s emphasis on intellectual inference and the entertaining of unasserted thoughts is a distortion of the phenomenology of cinematic absorption. According to Merleau-Ponty, such intellectual operations come into play in cases of breakdown but should not be read back into the primary absorbed experience as being implicitly operative all along. After presenting and criticizing Carroll’s view, I interpret and expand upon Merleau-Ponty’s position, showing that his version of the analogy between cinematic perception and everyday perception is more convincing than Carroll’s.     

Towards an epistemology of religious traditions

Summary Starting from the acceptance of the Egalitarian Principle I exhibited a version which I considered too lax (BEP) and one I considered too strict (NEP), arriving at a version (MEP) which allows that there can be tolerance-limiting reasons for adhering to traditions but only if they are based on unreasoned knowledge claims. In fact, I hold that the situation most of us find ourselves in restricts such claims on religious topics to very general ones. Hence the choice between NEP and MEP is not significant. It follows that we should take up one of two positions concerning religious traditions: either we argue from the shared assumptions of a variety of traditions without genuine participation in any of them; or we justify participation in one of them by noting various marks of reliability, such as serendipitous understanding. A version of this paper was read at the Faith and Reason Conference held at the Catholic Institute in Strathfield, October 5 and 6, 1996. I would like to thank all who participated in the discussion of my paper on that occasion. I would also like to thank the anonymous referees for Sophia for their helpful comments.     

Process causality and asymmetry

Process theories of causality seek to explicate causality as a property of individual causal processes. This paper examines the capacity of such theories to account for the asymmetry of causation. Three types of theories of asymmetry are discussed; the subjective, the temporal, and the physical, the third of these being the preferred approach. Asymmetric features of the world, namely the entropic and Kaon arrows, are considered as possible sources of causal asymmetry and a physical theory of asymmetry is subsequently developed with special reference to the questions of objectivity and backwards causation.An earlier draft of this paper was read at the A.A.P. conference at the University of Sydney, June, 1990. The author would like to thank Peter Menzies and Huw Price for their helpful comments.     

Making sense of the libertarian’s semantic claim about agential phenomenology

Libertarians about free will sometimes argue for their position on the grounds that our phenomenology of action is such that determinism would need to be false for it to be veridical. Many, however, have thought that it would be impossible for us to have an experience that is in contradiction with determinism, since this would require us to have perceptual experience of metaphysical facts. In this paper I show how the libertarian claim is possible. In particular, if experience depicts the world such that there is more than one physically possible future, then determinism would need to be false for that experience to be veridical. I show that we have experiences, or perceptual episodes, of this kind on the basis of recent work in the study of perception. Theorists in this area have argued that we have vision-for-action, and that what we visually perceive are not just objects but also possibilities for action. If we experience that it is possible that we ?, then we also experience that it is possible that we not ?. Furthermore, we probably experience more than one possibility for action at any one moment. I argue that these are physical possibilities, and therefore that we experience the world such that there is more than one physically possible future. So the libertarian claim about the semantics of agential phenomenology is highly plausible, even if this does not entail libertarianism.     

Smelling lessons

Much of the philosophical work on perception has focused on vision. Recently, however, philosophers have begun to correct this ‘tunnel vision’ by considering other modalities. Nevertheless, relatively little has been written about the chemical senses—olfaction and gustation. The focus of this paper is olfaction. In this paper, I consider the question: does human olfactory experience represents objects as thus and so? If we take visual experience as the paradigm of how experience can achieve object representation, we might think that the answer to this question is no. I argue that olfactory experience does indeed represent objects—just not in a way that is easily read from the dominant visual case.     

First-order modal theories

This paper is part of a general programme of developing and investigating particular first-order modal theories. In the paper, a modal theory of propositions is constructed under the assumption that there are genuinely singular propositions, ie. ones that contain individuals as constituents. Various results on decidability, axiomatizability and definability are established.I should like to thank the members of a metaphysics seminar at Irvine, and Peter Woodruff in particular, for several helpful discussions on the topic of this paper.     

Perceptual precision

The standard view in philosophy of mind is that the way to understand the difference between perception and misperception is in terms of accuracy. On this view, perception is accurate while misperception is inaccurate. However, there is some evidence (albeit controversial evidence) that perceptual experience actually involves widespread inaccuracy. I add to that evidence in the paper. Then I point toward a way of understanding the difference between perception and misperception, not in terms of accuracy alone, but in terms of precision. That is, I argue that perceptual experience is designed to enable more fine-grained discrimination among the properties that are most useful for action, even if that involves inaccuracy. The view in this paper motivates a new account of illusion, on which illusions are imprecise as well as inaccurate. I call this the Precision Account of Illusion.     

The reductionist ideal in cognitive psychology

I offer support for the view that physicalist theories of cognition don't reduce to neurophysiological theories. On my view, the mind-brain relationship is to be explained in terms of evolutionary forces, some of which tug in the direction of a reductionistic mind-brain relationship, and some of which which tug in the opposite direction. This theory of forces makes possible an anti-reductionist account of the cognitive mind-brain relationship which avoids psychophysical anomalism. This theory thus also responds to the complaint which arguably lies behind the Churchlands' strongest criticisms of anti-reductionism — namely the complaint that anti-reductionists fail to supply principled explanations for the character of the mind-brain relationship. While lending support to anti-reductionism, the view defended here also insures a permanent place for mind-brain reduction as an explanatory ideal analogous to Newtonian inertial motion or Aristotelian natural motion.I wish to thank the Synthese referees for their comments and suggestions. I also wish to thank Steve Bowen, Elise Brenner, and Arthur Fine for helpful discussions and Joseph Owens for his comments on a version of this paper read at the Central Division Meetings of the American Philosophical Association held in Cincinnati in April 1988.     

Empathy and the responsiveness to social affordances

The direct perception theory of empathy claims that we can immediately experience a person’s state of mind. I can see for instance that my neighbour is angry with me in his bodily countenance. I develop a version of the direct perception theory of empathy which takes this perceptual capacity to depend upon recognising in what way the other person is responsive to the affordances the environment provides. By recognising which possibilities for action are relevant to a person, I can thereby understand something about the meaning they give to the world. I come to share something of their perspective on the world, and this allows me to grasp based on my perception of them something about their current state of mind. I argue that shared affect plays a central role in this perceptual capacity. Shared affect allows me to orient my attention to possibilities for action that matter to the other person. I end by briefly discuss the implications of this view of empathy for the disturbances in so-called “cognitive empathy” that are found in people diagnosed with autism spectrum disorder.     

Moral education: An act-utilitarian view1

In this essay, I distinguish two significant act-utilitarian theories of moral education: the traditional rule of thumb view and the Harian intuition view. I argue that there are problems with the traditional view and that an act-utilitarian ought to adopt a version of the Harian view. I then explain and respond to a major objection to the intuition view given by Bernard Williams. Williams argues that the system of moral thought which the Harian view advocates we teach is inherently unstable and is certain to undermine itself. I argue that there is reason to expect a great deal of stability in this system.I wish to thank Richard Brandt, William Frankena and R.M. Hare for their conversation on this and other topics and for their comments on earlier drafts of this paper. I would also like to thank the Association for the Philosophy of Education and the Northwest Philosophy conference for the opportunity to read and discuss versions of the essay.
