1. Introduction. Like other direct realists, Thomas Reid offered an alternative to indirect realist and idealist accounts of perception. Reids alternative aimed to preserve the indirect realists commitment to realism about the objects of perception, and the idealists commitment to the immediacy of the minds relation to the objects of perception. Reid holds that what you perceive is mind independent or external; and your relation to such objects in perception is direct or immediate. In his own words, something which is extended and solid, which may be measured and weighed, is the immediate object of my touch and sight. And this object I take to be matter, and not an idea (IP II xi, 154).

The foundation of phenomenological image theories is the view that image perception leads to a perception sui generis . In order to grasp this peculiarity of image perception, two ways have traditionally been considered: either through a description of the particular object of image perception or through a description of the unique origin of image perception. This article explores a third way within the phenomenology of the image by trying to determine the uniqueness of image perception through its peculiar, necessary effects on the observer of the image. The thesis is: The observer of an image does not become an image object in the image. It is only in the case of image perception that there is relief through a gap in participation. It is the perception of something without the demand, as the perceiving person, of being physically involved in what is perceived.

A theory of perception must be capable of explaining the full range of conscious perception, including amodal perception. In amodal perception we perceive the world to contain physical features that are not directly detectable by the sensory receptors. According to the active-externalist theory of perception, amodal perception depends on active engagement with perceptual objects. This paper focuses on amodal visual perception and presents a counter-example to the idea that active-externalism can account for amodal perception. The counterexample involves the experience of so-called ‘impossible objects’, objects experienced in perceptual character as having geometrical properties that no physically real object can have.

As our chief aim is a comprehensive theory of perception which will cover all the facts, ... JR Smythies' Analysis of Perception I discuss in Ch. VI, § 6. ...

In discussions of perception and its relation to knowledge, it is common to distinguish what one comes to believe on the basis of perception from the distinctively perceptual basis of one's belief. The distinction can be drawn in terms of propositional contents: there are the contents that a perceiver comes to believe on the basis of her perception, on the one hand; and there are the contents properly attributed to perception itself, on the other. Consider the content.

An attempt is made to pinpoint the way in which perception is related to belief. Although, for familiar reasons, it is not true to say that we necessarily believe in the existence of the objects we perceive, nor that they actually have their ostensible characteristics, it is argued that the relation between perception and belief is more than merely contingent There are two main issues to address. The first is that `collateral' beliefs may impede perceptual belief. It is argued that this still assigns an essential role to belief in perception, though the belief may be of an attenuated form. The second is Fred Dretske's claim that even attenuated belief may be entirely absent from perception. It is argued that (a) `non-epistemic' perception can be understood only by employing the concept of `epistemic' perception; (b) that the former can occur only partially-i.e., within perceptions that are otherwise epistemic; and (c) that by switching attention from the perception of objects to the Phenomenological tradition's concern with the perception of world, we can see that perception must be entirely permeated with `doxastic' force.

Michael Jacovides For Locke, the first step in inquiring into perception should be reflection: “What Perception is, every one will know better by reflecting on what he does himself, when he sees, hears, feels, etc. or thinks, than by any discourse of mine” (2.9.2). As a second step, I say, we may learn from reading him. Locke’s use of the term ‘perception’ is somewhat broad. At one point, he tells us that “having Ideas and Perception” are “the same thing” (2.1.9). Elsewhere, he includes the perceiving the agreement of ideas and perceiving the meaning of signs among the varieties of perception (2.21.5). What I have to say will be about perception as psychologists classify it nowadays. I will first discuss sensation in general and then elucidate some of the subtleties of Locke’s account of the visual perception of shape. I’ll close with some remarks on Locke account of time perception.

Thomas Reid's distinction between original and acquired perception is not merely metaphysical; it has psychological and phenomenological stories to tell. Psychologically, acquired perception provides increased sensitivity to features in the environment. Phenomenologically, Reid's theory resists the notion that original perception is exhaustive of perceptual experience. James Van Cleve has argued that most cases of acquired perception do not count as perception and so do not pose a threat to Reid's direct realism. I argue that acquired perception is genuine perception and as direct as original perception. Perception is grounded in a productive and developing relationship between the mind and world.
