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.

I show that Nietzsche's puzzling and seemingly inconsistent claims about consciousness constitute a coherent and philosophically fruitful theory. Drawing on some ideas from Schopenhauer and F.A. Lange, Nietzsche argues that conscious mental states are mental states with conceptually articulated content, whereas unconscious mental states are mental states with non-conceptually articulated content. Nietzsche's views on concepts imply that conceptually articulated mental states will be superficial and in some cases distorting analogues of non-conceptually articulated mental states. Thus, the claim that conscious states have a conceptual articulation renders comprehensible Nietzsche's claim that consciousness is "superficial" and "falsifying.".

It is widely held that there is an important distinction between the notion of consciousness as it is applied to creatures and, on the other hand, the notion of consciousness as it applies to mental states. McBride has recently argued in this journal that whilst there may be a grammatical distinction between state consciousness and creature consciousness, there is no parallel ontological distinction. It is argued here that whilst state consciousness and creature consciousness are indeed related, they are distinct properties. Conscious creatures can have, at one time, both conscious and unconscious mental states. This raises the question of what distinguishes the conscious from unconscious mental states of a subject: a question about what state consciousness consists in. Whilst the state/creature distinction may not be of use in explaining every aspect of a subject's consciousness, it does provide a key part of the explanandum for theories of consciousness and mind. The state/creature consciousness distinction is a real one and should not be dropped from our psychological taxonomy.

Few contemporary researchers in psychology, philosophy, and the cognitive sciences have any doubt about whether mental phenomena occur without being conscious. There is extensive and convincing clinical and experimental evidence for the existence of thoughts, desires, and related mental states that aren’t conscious. We characterize thoughts, desires, intentions, expectations, hopes, and many other mental states in terms of the things they are about and, more fully, in terms of their content, as captured by a sentence nominalization, such as a clause beginning with the word ‘that’. The philosophical literature follows Franz Brentano’s adaptation of Thomist terminology in referring to all such states as intentional states. But there is another type of mental phenomena, which lack intentionality and whose mental nature consists instead of some qualitative feature. These states include bodily sensations, such as aches and pains, and perceptual states, such as visual sensations of color and tactile sensations of heat and cold. And these states all exhibit some mental quality or another, such as the mental quality distinctive of pain or the mental quality of red or blue.1 And even theorists who acknowledge that intentional states can and do occur without being conscious have sometimes insisted that qualitative states cannot. There is, according to these theorists, nothing to a state’s being qualitative or exhibiting some mental quality unless that state is conscious – unless it is, as we might metaphorically say, “lighted up”. It’s striking that Freud himself seems to have adopted this double standard toward the two types of mental state. In his metapsychological paper, “The Unconscious”, for example, he writes that “all the categories which we employ to describe conscious mental acts, such as ideas, purposes, resolutions, and so forth, can be applied to [unconscious mental occurrences]” (Freud 1915e, p. 168). But he seems here to have in..

What, in essence, characterizes the mind? According to Searle, the potential to be conscious provides the only definitive criterion. Thus, conscious states are unquestionably "mental"; "shallow unconscious" states are also "mental" by virtue of their capacity to be conscious (at least in principle); but there are no "deep unconscious mental states" - i.e. those rules and procedures without access to consciousness, inferred by cognitive science to characterize the operations of the unconscious mind are not mental at all. Indeed, according to Searle, they have no ontological status - they are simply ways of describing some interesting facets of purely physiological phenomena.

Philosophers, especially in recent years, have engaged in reflection upon the nature of experience. Such reflections have led them to draw a distinction between conscious and unconscious mentality in terms of whether or not it is like something to have a mental state. Reflection upon the history of psychology and upon contemporary cognitive science, however, identifies the distinction between conscious and unconscious mental states to be primarily one which is drawn in epistemic terms. Consciousness is an epistemic notion marking the special kind of first-person knowledge we have of our own mental states. Psychologists have found it expedient, for explanatory reasons, to ignore or reject the assumption that we have exhaustive first-person knowledge of our mental states and, in doing so, use the term 'unconscious' to indicate the peculiar epistemic status of certain mental states.It is argued that epistemic consciousness is distinct from the subjective-experiential notion of consciousness, from 'access-consciousness' and from higher-order thought conceptions of mental state consciousness, and that epistemic consciousness has an important role to play in philosophy of mind and in the history of psychology.

p0005 The term ‘consciousness’ is used in several ways: to describe a person or other creature as being awake and sentient, to describe a person or other creature as being ‘aware of ’ something, and to refer to a property of mental states, such as perceiving, feeling, and thinking, that distinguishes those states from unconscious mental states. Distinguishing these different concepts of consciousness is crucial in evaluating the major theories of what it is for a state to be conscious. Among those are first-order theories, on which a mental state is conscious if being in that state results in one’s being conscious of something; global-workspace theories, on which a state is conscious if it’s widely available for mental processing; inner-sense theories, on which a state is conscious if one senses or perceives that state by way of a special inner faculty; and higher-orderthought theories, on which a state is conscious if one is aware of that state by having a thought about it. We will consider the advantages and shortcomings of these theories and variants of them.

When a mental state is conscious – in the sense that there is something it is like for the subject to have it – it instantiates a certain property F in virtue of which it is a conscious state. It is customary to suppose that F is the property of having sensory quality. The paper argues that this supposition is false. The first part of the paper discusses reasons for thinking that unconscious mental states can have a sensory quality, for example in cases of absent-minded perception. If unconscious mental states can have a sensory quality, then sensory quality is an insufficient condition for consciousness. The second part of the paper argues that there are even better reasons to think that sensory quality is an unnecessary condition for consciousness. The idea is that mental states can be conscious even when they lack sensory quality, for example, in the case of certain conscious propositional attitudes. In the third part of the paper, an alternative to the rejected supposition, drawn from the phenomenological tradition, is offered: that consciousness is a matter of implicit self-awareness, rather than of sensory quality. According to this alternative, a mental state is conscious when, and only when, it involves implicit self-awareness.

In general, the idea is that what makes a mental state conscious is that it is the object of some kind of higher-order representation (HOR). A mental state M becomes conscious when there is a HOR of M. A HOR is a “meta-psychological” state, i.e. a mental state directed at another mental state. So, for example, my desire to do a good powerpoint presentation becomes conscious when I am (non-inferentially) “aware” of the desire. Intuitively, it seems that conscious states, as opposed to unconscious ones, are mental states that I am “aware of” in some sense.
