Traditionally conceived, introspection is a form of nonsensuous perception that allows the mind to scrutinize at least some of its own states while it is experiencing them. The traditional account of introspection has been in disrepute ever since Ryle argued that the very idea of introspection is a logical muddle. Recent critics such as William Lyons, John Searle, and Sydney Shoemaker argue that this disrepute is well-deserved. Three distinct objections to the traditional account of introspection are considered and rejected. It is argued that critics of the traditional account of introspection fail to adequately distinguish potential objects of introspection. Further, it is argued that at least two cognitive states are properly understood as objects of introspection. The conclusions reached suggest that there are sufficient reasons to reconsider ther merits of the traditional account of introspection.

In the last of his three Royce Lectures called "Self‑Knowledge and 'Inner Sense'", Sydney Shoemaker attempts to reconcile two commitments: (1) that experiences have "qualia", nonrepresentational features that constitute what it is like to have the experiences, and (2) that perceptual experiences seem "diaphanous", yielding to introspection only the way they represent the environment, not intrinsic or otherwise nonrepresentational qualia. On the idea that we internally sense qualia�that we sense what our experiences are like�one way to explain apparent diaphanousness is to maintain that these qualia are mistakenly "projected" onto the environment, that in perception we erroneously sense qualia as belonging to environmental objects. Shoemaker rejects both the projection view and the existence of inner sense, and develops an alternative reconciliation. I will describe reasons to doubt his positive proposal, and ways to save projection and inner sense from his criticisms.

Sydney Shoemaker argues that introspection, unlike perception, provides no identification information about the self, and that knowledge of one''s mental states should be conceived as arising in a direct and unmediated fashion from one''s being in those states. I argue that while one does not identify aself as the subject of one''s states, one does frequently identify and misidentify thestates, in ways analogous to the identification of objects in perception, and that in discourse about one''s mental states the self plays the role of external reality in discourse about physical objects. Discourse about any sort of entity or property can be viewed as involving a domain or frame of reference which constrains what can be said about the entities; this view is related to Johnson-Laird''s theory of mental models. On my approach evidence, including sensory evidence, may be involved in decisions about one''s mental states. I conclude that while Shoemaker may well be right about different roles for sense impressions in introspection and perception, the exact differences and their significance remain to be established.

I investigate the way in which our conscious judgments can be a guide to our beliefs, a topic discussed by Gareth Evans, Richard Moran, Christopher Peacocke, and Alex Byrne, among others. I argue that our conscious judgments can give us a kind of justification to self-ascribe beliefs which is (i) distinctively first-personal, (ii) non-inferential, and (iii) fallible. I then defend my view from a challenge from "constitutivist" views in the epistemology of introspection, defended by philosophers such as Sydney Shoemaker, according to which only our beliefs themselves give us justification to self-ascribe beliefs.

What is introspective knowledge of one's own intentional states like? This paper aims to make plausible the view that certain cases of self-knowledge, namely the cogito-type ones, are enough like perception to count as cases of quasi-observation. To this end it considers the highly influential arguments developed by Sydney Shoemaker in his recent Royce Lectures. These present the most formidable challenge to the view that certain cases of self-knowledge are quasi-observational and so deserve detailed examination. Shoemaker's arguments are directed against two models of ordinary perception, the "object perception model" and the "broad perceptual model". I argue that the core theses that Shoemaker associated with them are either dubious in their own right or applicable to certain cases of self-knowledge. Overall the aim is to show that there is such a variety of patterns in each case that simple analogies or disanalogies are unhelpful.

In a number of papers, Sydney Shoemaker has argued that first-order belief plus rationality implies second-order belief. This paper is a critical discussion of Shoemaker's argument.

Propositions such as <It is raining, but I do not believe that it is raining> are paradoxical, in that even though they can be true, they cannot be truly asserted or believed. This is Moore’s paradox. Sydney Shoemaker has recently ar- gued that the paradox arises from a constitutive relation that holds between first- and second-order beliefs. This paper explores this approach to the paradox. Although Shoemaker’s own account of the paradox is rejected, a different account along similar lines is endorsed. At the core of the endorsed account is the claim that conscious beliefs are always partly about themselves; it will be shown to follow from this that conscious beliefs in Moorean propositions are self-contradictory.
