While there is virtually a consensus among contemporary philosophers of perception that some form of direct realism is true, there is less than complete agreement about whether normal, direct perceptions involve mental inferences in any sense. In taking another look at this recurrent question, my aim is twofold: first, to examine some of the arguments and evidences that have been offered in favor of inferences and to see if they can be accommodated within the direct realist framework, and second, to attempt to clarify and defend the insight of direct realism that normal perceptions are noninferential.

In at least some cases of justified perceptual belief, our perceptual experience itself, as opposed to beliefs about it, evidences and thereby justifies our belief. While the phenomenon is common, it is also mysterious. There are good reasons to think that perceptions cannot justify beliefs directly, and there is a significant challenge in explaining how they do. After explaining just how direct perceptual justification is mysterious, I considerMichael Huemers (Skepticism and the Veil of Perception, 2001) and Bill Brewers (Perception and Reason, 1999) recent, but radically different, attempts to eliminate it. I argue that both are unsuccessful, though a consideration of their mistakes deepens our appreciation of the mystery.

The goal of this paper is to defend the claim that there is such a thing as direct perception, where by ‘direct perception’ I mean perception unmediated by theorizing or concepts. The basis for my defense is a general philosophic perspective which I call ‘empiricist philosophy’. In brief, empiricist philosophy (as I have defined it) is untenable without the occurrence of direct perception. It is untenable without direct perception because, otherwise, one can't escape the hermeneutic circle, as this phrase is used in van Fraassen (1980). The bulk of the paper is devoted to defending my belief in direct perception against various objections that can be posed against it. I discuss various anticipations of my view found in the literature, eventually focusing on Ian Hacking's related conception of `entity realism' (Hacking 1983). Hacking has been criticized by a number of philosophers and my plan is to respond to these criticisms on behalf of entity realism (or more precisely on behalf of the claim that direct perception is a reality) and to then respond to other possible criticisms that can be launched against direct perception.

Direct Realists believe that perception involves direct awareness of an object not dependent for its existence on the perceiver. Howard Robinson rejects this doctrine in favour of a Sense-Datum theory of perception. His argument against Direct Realism invokes the principle ‘same proximate cause, same immediate effect’. Since there are cases in which direct awareness has the same proximate cerebral cause as awareness of a sense datum, the Direct Realist is, he thinks, obliged to deny this causal principle. I suggest that although Direct Realism is in more than one respect implausible, it does not succumb to Robinson’s argument. The causal principle is true only if ‘proximate cause’ means ‘proximate sufficient cause’, and the Direct Realist need not concede that there is a sufficient cerebral cause for direct awareness of independent objects.

In this paper, I attempt to demonstrate the structure of Sellars' critical direct realism in the philosophy of perception. This position is original because it attempts to balance two claims that many have thought to be incompatible: (1) that perceptual knowledge is direct, i.e., not inferential, and (2) that perceptual knowledge is irreducibly conceptual. Even though perceptual episodes are not the result of inferences, they must still stand within the space of reasons if they are to be counted not only as knowledge, but also as thoughts directed at the world. The goal of this paper is to demonstrate how Sellars elaborates and defends this position.

This book develops and defends a version of direct realism: the thesis that perception gives us direct awareness, and non-inferential knowledge, of the external...

When philosophers speak of direct perceptual knowledge, they obviously mean to suggest that such knowledge is unmediated ? but unmediated by what? This is where we find evidence of violent disagreement. To clarify matters, I want to identify and briefly describe several important senses of "direct" that have helped shape our understanding of perceptual knowledge. They are (1) "Direct" as Non-Inferential Perception; (2) "Direct" as Unmediating by Objects of Perception; (3) "Direct" as Conceptually Unmediated Perception; (4) "Direct" as Independent Verification of Perceptual Beliefs; and (5) "Direct" as Perception of What is Epistemically Prior.
