The outlines of a novel, fully naturalistic theory of perception are provided, that can explain perception of an object X by organism Z in terms of reflexive causality. On the reflexive view proposed, organism Z perceives object or property X just in case X causes Z to acquire causal dispositions reflexively directed back upon X itself. This broadly functionalist theory is potentially capable of explaining both perceptual representation and perceptual content in purely causal terms, making no use of informational concepts. However, such a reflexive, naturalistic causal theory must compete with well entrenched, supposedly equally naturalistic theories of perception that are based on some concept of information, so the paper also includes some basic logical, naturalistic and explanatory criticisms of such informational views.

According to a classical causal account of perception, to perceive that object x is F is to fulfill the following conditions: (i) one has an experience as of x's being F, (ii) x is F, and (iii) one's experience of x's being F depends causally on x's being F. This is the core of Grice's causal theory of perception, and it is initially quite plausible (Grice 1961).

This paper explores some issues having to do with the perception of causation. It discusses the role that phenomena that that are associated with causal perception, such as Michottean launching interactions, play within philosophical accounts of causation and also speculates on their possible role in development.

Much recent discussion about the nature of perception has focused on the dispute between the Causal Theory of Perception and the rival Disjunctive View. There are different versions of the Causal Theory (the abbreviation I shall use), but the point upon which they agree is that perception involves a conscious experience which is logically distinct from the particular physical object perceived. 1 On the opposed Disjunctive View, the perceptual experience is held to be inseparable from the object perceived; what is directly present to conscious experience is, literally, part of the physical environment. 2 One prima facie difficulty the Causal Theory appears to face is the problem of deviant causal chains, of providing sufficient conditions for perception; I shall not address this difficulty directly, though some of my concluding remarks will bear on it. My main aim in this paper is to show that, despite the deviant causal chains problem, the Causal Theory is to be preferred to the rival Disjunctive View.

Can humans see causal interactions? Evidence on the visual perception of causal interactions, from Michotte to contemporary work, is best interpreted as showing that we can see some causal interactions in the same sense as that in which we can hear speech. Causal perception, like speech perception, is a form of categorical perception.

This paper presents a theory of how perception provides a basis for moral knowledge. To do this, the paper sketches a theory of perception, explores the sense in which moral perception may deserve that name, and explains how certain moral properties may be perceptible. It does not presuppose a causal account of moral properties. If, however, they are not causal, how can we perceive, say, injustice? Can it be observable even if injustice is not a causal property? The paper answers these and other questions by developing an account of how moral properties, even if not causal, can figure in perception in a way that grounds moral knowledge.
