Self-knowledge is knowledge of one’s own states (or processes) in an indexical mode of presentation. The philosophical debate is concentrating on mental states (or processes). If we characterize self-knowledge by natural language sentences, the most adequate utterance has a structure like “I know that I am in mental state M”. This common sense characterization has to be developed into an adequate description. In this investigation we will tackle two questions: (i) What precisely is the phenomenon referred to by “self-knowledge” and how can we adequately describe a form of self-knowledge which we might realistically enjoy? (ii) Can we have self-knowledge given the fact that the meaning of some words which we utter depends on the environment or the speech community? The theory we defend argues that we have to distinguish the public meaning of utterances, on the one hand, and the mental representations which are constituting a mental state of an individual, on the other. Self-knowledge should be characterized on the level of mental representations while the semantics of utterances self-attributing mental states should be treated separately. Externalism is only true for the public meaning of utterances but not for beliefs and other mental states including self-knowledge.

Traditionally, it has been supposed that both minds and mental states are unobservable. If the mind and its contents are hidden in this way, our knowledge of others' mental lives would have to be indirect. In this thesis, I argue that it is not plausible-to suppose that all of our knowledge, of others mental lives is indirect. It is more plausible to suppose that sometimes, we can perceive others' mental states. Thereby, we can sometimes come to have direct, perceptual knowledge of when another is in some mental state’ The hypothesis that we can sometimes perceive each others' mental states is plausible because it is possible, and because if it were true, it would bestexplain our knowledge of others' mental states. It is possible to perceive others' mental states, because others' behaviours need not conceal those states. Rather, what behaviour sometimes does is to reveal another's mental state. When behaviour acts this way, knowledge of another's mental state need not rest on any beliefs about their behaviour. If others' behaviour could inform us of their mental states only in so far as it could be our evidence of their mental states, then the evidence it would provide could not be sufficient to secure all the knowledge we take ourselves to have about others’ mental states. If so, the claim that all we have to go on in discovering how others think or feel is the evidence of their behaviour could not hope to explain that knowledge. So, only if it were true that others' behaviour sometimes enabled us to perceive their mental states could we adequately explain all our knowledge of their mental states. For these reasons, I claim that the hiddenness of the mental is a myth.

Vendler, Res Cogitans Knowing that one wants to go to the movies is an example of self-knowledge, knowledge of one’s mental states. It may be foolish to ask the man on the Clapham Omnibus how he knows what he wants, but the question is nonetheless important — albeit neglected by epistemologists. This paper attempts an answer. Before getting to that, the familiar claim that we enjoy “privileged access” to our mental states needs untwining (section 1). A sketch of a theory of knowledge of one’s beliefs that has received some attention in the recent literature (section 2), and the case for extending that account to self-knowledge in general (section 3), sets the stage for our answer to the main question (section 4).

A self-ascription is a thought or sentence in which a predicate is self-consciously ascribed to oneself. Self-ascriptions are best expressed using the first-person pronoun. Mental self-ascriptions are ascriptions to oneself of mental predicates (predicates that designate mental properties), non-mental self-ascriptions are ascriptions to oneself of non-mental predicates (predicates that designate non-mental properties). It is often claimed that there is a range of self-ascriptions that are immune to error through misidentification relative to the first-person pronoun (IEM for short). What this means, and exactly which self-ascriptions are properly classed as IEM, is a topic hotly disputed. Some claim that only mental self-ascriptions are IEM, others claim that some non-mental self-ascriptions are IEM. Before this question can be decided, it needs to be judged exactly what it means to say that a self-ascription is IEM. And here we stumble across the fact that there are, at least, two non-equivalent ways of defining the phenomenon1. I will be claiming that one of these definitions should be rejected.

In this paper, I propose an account of self-knowledge for desires. According to this account, we form beliefs about our own desires on the basis of our grounds for those desires. First, I distinguish several types of desires and their corresponding grounds. Next, I make the case that we usually believe that we have a certain desire on the basis of our grounds for it. Then, I argue that a belief formed thus is epistemically privileged. Finally, I compare this account to two other similar accounts of self-knowledge.

* Argument from authoritative self-knowledge ("privileged access" to one's own mental states) 1. We have a "privileged access" to our own mental states in the sense we have the authority on what mental states we are in. 2. Through introspection, we are aware of our mental states but not aware of them as physical states of any sort or as functional states. 3. Therefore, our mental states cannot be physical states.

Many philosophers accept a “privileged access” thesis concerning our own present mental states and mental events. According to these philosophers, if I am in mental state (or undergoing mental event) M, then – at least in many cases – I have privileged access to the fact that I am in (or undergoing) M. For instance, if I now believe that my cat is sitting on my lap, then (in normal circumstances) I have privileged access to the fact that I now believe that my cat is sitting on my lap. Similarly, if I now imagine a parade coming down Main Street, then (again, in normal circumstances) I have privileged access to the fact that I am now imagining a parade coming down Main Street. And again, if it now visually appears to me as if there is a cloud in the sky, then (again, in normal circumstances) I have privileged access to the fact that it now visually appears to me as if there is a cloud in the sky. In each of these aforementioned cases, if circumstances are normal, then, these philosophers say, I have a distinctive kind of privileged epistemic access to facts about my own mental states or events. Of course, I don’t have privileged epistemic access to all facts about my own mental states or events. For instance, I don’t have privileged epistemic access to facts about which unconscious mental states or events I have. But I do have privileged epistemic access to many facts about my own mental states or events, and in particular to the various facts listed above.

According to one of the most influential views in the philosophy of self-knowledge each person enjoys some special cognitive access to his or her own current mental states and episodes. This view faces two fundamental tasks. First, it must elucidate the general conceptual structure of apparent asymmetries between beliefs about one’s own mind and beliefs about other minds. Second, it must demarcate the mental territory for which first-person-special-access claims can plausibly be maintained. Traditional candidates include sensations, experiences (of various kinds), thoughts, beliefs, desires, and also affective states such as emotions. I reconstruct five prominent privileged access claims that have traditionally been maintained for emotions and discuss logical relations among them. I then argue that none of these claims stands up to scrutiny. The truth is that we often suffer from affective ignorance, and that third-person ascriptions of emotional states should often be credited with more rather than less authority than corresponding self-ascriptions. I conclude by considering, and rejecting, five potential objections to my argument.

The purpose of this essay is to account for privileged access or, more precisely, the special kind of epistemic right that we have to some beliefs about our own mental states. My account will have the following two main virtues. First of all, it will only appeal to those conceptual elements that, arguably, we already use in order to account for perceptual knowledge. Secondly, it will constitute a naturalizing account of privileged access in that it does not posit any mysterious faculty of introspection or "inner perception" mechanism.
