- Tim Crane (2007). Intentionalism. In Ansgar Beckermann & Brian P. McLaughlin (eds.), Oxford Handbook to the Philosophy of Mind. Oxford University Press.The central and defining characteristic of thoughts is that they have objects. The object of a thought is what the thought concerns, or what it is about. Since there cannot be thoughts which are not about anything, or which do not concern anything, there cannot be thoughts without objects. Mental states or events or processes which have objects in this sense are traditionally called ‘intentional,’ and ‘intentionality’ is for this reason the general term for this defining characteristic of thought. Under the heading of ‘thought’ we can include many different kinds of mental apprehension of an object—including relatively temporary episodes of contemplating or scrutinising, as well as persisting states like beliefs and hopes which are not similarly episodic in character. These are all ways of thinking about an object. But even construing ‘thought’ in this broad way, it is clear that not all mental states and events are thoughts: sensations, emotions and perceptual experiences are not thoughts, but they are also paradigmatically mental. Do these mental states and events have objects too? Or are there mental states and events which have no objects? 1 The view that all mental phenomena have objects is sometimes called ‘Brentano’s thesis’ or the thesis that intentionality is the ‘mark’ of the mental.1 Sometimes the name ‘Brentano’s thesis’ is given to certain other views too: for example, to the view that only mental phenomena are intentional, or that all and only mental phenomena are intentional, or that nothing physical is intentional. These views are, however, distinct from the view that all mental phenomena are intentional. For holding that all mental phenomena are intentional does not imply that nothing nonmental is.2 And holding that all mental phenomena are intentional does not imply (pace Dennett 1969) that nothing physical is intentional; since if physicalism were true, then the mental itself would be physical. What I am concerned with here, however, is the idea that all mental states are intentional, regardless of whether anything else is, or whether anything physical is. In recent years there has been considerable debate over whether all mental states are intentional; in particular, over whether all conscious mental states are intentional or entirely intentional.

The crucial point of the mind-body-problem appears to be that mental phenome- na (events, properties, states) seem to have features which at first sight make it impossible to integrate these phenomena into a naturalistic world view, i.e. to identify them with, or to reduce them to, physical phenomena.1 In the contemp- orary discussion, there are mainly two critical features which are important in this context. The first of these is the feature of intentional states, e.g. beliefs and desires, to have a representational or semantic content. The problem of the naturalization of these states I will call the problem of intentionality. The second critical feature is the property of other mental states, e.g. perceptions and sensations, to have a qualitative aspect, i.e. that it is somehow, or feels in a characteristic way, to be in one of those states. The problem of the naturalization of these states is generally called the qualia-problem.
I. the view that reasons cannot be causes. II. the view that the explanatory relevance of psychological states such as beliefs and intentions derives from their content, their explanatory role is not causal and we thus have no good reason to ascribe causal power to them. III. the idea that if the mental supervenes on the physical, then what really explains our actions is the physical properties determining our propositional attitudes, and not those attitudes themselves. IV. the thesis that since there are no laws linking (intentional) mental states to actions, those states cannot be genuine causes of action.
Consciousness and intentionality are perhaps the two central phenomena in the philosophy of mind. Human beings are conscious beings: there is something it is like to be us. Human beings are intentional beings: we represent what is going on in the world.Correspondingly, our specific mental states, such as perceptions and thoughts, very often have a phenomenal character: there is something it is like to be in them. And these mental states very often have intentional content: they serve to represent the world. On the face of it, consciousness and intentionality are intimately connected. Our most important conscious mental states are intentional states: conscious experiences often inform us about the state of the world. And our most important intentional mental states are conscious states: there is often something it is like to represent the external world. It is natural to think that a satisfactory account of consciousness must respect its intentional structure, and that a satisfactory account of intentionality must respect its phenomenological character.With this in mind, it is surprising that in the last few decades, the philosophical study of consciousness and intentionality has often proceeded in two independent streams. This wasnot always the case. In the work of philosophers from Descartes and Locke to Brentano and Husserl, consciousness and intentionality were typically analyzed in a single package. But in the second half of the twentieth century, the dominant tendency was to concentrate on onetopic or the other, and to offer quite separate analyses of the two. On this approach, the connections between consciousness and intentionality receded into the background.In the last few years, this has begun to change. The interface between consciousness and intentionality has received increasing attention on a number of fronts. This attention has focused on such topics as the representational content of perceptual experience, the higherorder representation of conscious states, and the phenomenology of thinking. Two distinct philosophical groups have begun to emerge. One group focuses on ways in which consciousness might be grounded in intentionality. The other group focuses on ways in which intentionality might be grounded in consciousness.
What is the relationship between phenomenology and intentionality? A common picture in recent philosophy of mind has been that the phenomenal aspects and the intentional aspects of mentality are independent of one another. According to this view, the phenomenal character of certain mental states or processes”states for which there is "something it is like" to undergo them—is not intentional. Examples that are typically given of states with inherent phenomenal character are sensations, such as pains, itches, and color sensations. This view also asserts, on the other hand, that the intentionality of certain mental states and processes their "being about something" is not phenomenal. Beliefs and desires are the paradigm cases of intentional mental states. Although they are intentionally directed (i.e., they have aboutness) these mental states are not inherently phenomenal. There is nothing that it is like to be in such a state by virtue of which it is directed toward what it is about. We will call this picture separatism, because it treats phenomenal aspects of mentality and intentional aspects of mentality as mutually independent, and thus separable. Although there may be complex states that are both phenomenal and intentional, their phenomenal aspects and their intentional aspects are separable. Many philosophers who hold this picture have thought that these two aspects of mentality lead to quite different sorts of problems with respect to the project of “naturalizing the mental.†Proponents of separatism often hold that while the problem of naturalizing phenomenology poses great difficulties, the problem of naturalizing intentionality is much..
Intentionality, as Brentano originally introduced the term in modern philosophy, was meant to provide a distinctive characteristic definitively separating the mental from the physical.(1) Mental states have an intrinsic relationship to an object, to that which they are "about." Physical entities just are what they are, they cannot, by their very essence, refer to anything, they have no "outreach", as one might put it. Mental states have, as it were, an incomplete essence, they cannot exist at all unless they are completed by something other than themselves, their object. Brentano's position is opposed to all theories which represent the mental as only extrinsically related to the world, that is, to all theories in which mental states are themselves self-sufficient for their own existence and only secondarily relate to the world by means of something external to their nature, e.g., neurological causation, divine intervention, or pre-established harmony. In these later cases, any mental act whatsoever could be related to any object, or indeed to none, for the relation is external to the nature of the act, it is superimposed on it by outside forces. Brentano's point is that a mental act has, by its very essence, an Intentional object without which it would not be a mental act. It would therefore appear that since causality is an external relationship which could in principle relate any two things regardless of their nature, the Intentional relation between an act and its object cannot be a causal relation.
After Brentano, intentionality is often characterized as “the mark of the mental”. In Brentano‟s view, intentionality “is characteristic exclusively of mental phenomena. No physical phenomenon manifests anything like it”. 2 After Meinong, it is also generally believed that intentionality, as this characteristic mental phenomenon, concerns a specific type of objects, namely, intentional objects, having intentional inexistence, as opposed to ordinary physical objects, having real existence. Thus, intentional objects are supposed to constitute a mysterious ontological realm, the dwelling place of the objects of dreams and fiction, and other “weird entities”, even inconsistent objects, such as round squares. Finally, it is also generally held that intentionality somehow defies logic, as the well-known phenomena of the breakdown of the substitutivity of identicals, the failure of existential generalization, and generally the strange behavior of quantification in intentional contexts testify. In this paper, I will refer to these positions as the psychological, ontological, and logical “myths of intentionality”, respectively. The reason is that although this important modern notion of intentionality and the positions involving it are supposed to have come from medieval philosophy, medieval philosophers would be starkly opposed to them. On the basis of the relevant doctrines of some medieval philosophers, especially, Aquinas and Buridan, this paper is going to argue that the three positions on intentionality described above are in fact just three modern myths.
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..
‘It is of the very nature of consciousness to be intentional’ said Jean-Paul Sartre, ‘and a consciousness that ceases to be a consciousness of something would ipso facto cease to exist’.1 Sartre here endorses the central doctrine of Husserl’s phenomenology, itself inspired by a famous idea of Brentano’s: that intentionality, the mind’s ‘direction upon its objects’, is what is distinctive of mental phenomena. Brentano’s originality does not lie in pointing out the existence of intentionality, or in inventing the terminology, which derives from scholastic discussions of concepts or intentiones.2 Rather, his originality consists in his claim that the concept of intentionality marks out the subject matter of psychology: the mental. His view was that intentionality ‘is characteristic exclusively of mental phenomena. No physical phenomenon manifests anything like it’.3 This is Brentano’s thesis that intentionality is the mark of the mental. Despite the centrality of the concept of intentionality in contemporary philosophy of mind, and despite the customary homage paid to Brentano as the one who revived the terminology and placed the concept at the centre of philosophy, Brentano’s thesis is widely rejected by contemporary philosophers of mind. What is more, its rejection is not something which is thought to require substantial philosophical argument. Rather, the falsity of the thesis is taken as a starting-point in many contemporary discussions of intentionality, something so obvious that it only needs to be stated to be recognised as true. Consider, for instance, these remarks from the opening pages of Searle’s Intentionality: Some, not all, mental states and events have Intentionality. Beliefs, fears, hopes and desires are Intentional; but there are forms of nervousness, elation and undirected anxiety that are not Intentional.... My beliefs and desires must always be about something. But my nervousness and undirected anxiety need not in that way be about anything.4 Searle takes this as obvious, so obvious that it is not in need of further argument or elucidation.
I question Brentano's thesis that all and only mental phenomena are
intentional. The common gloss on intentionality in terms of
directedness does not justify the claim that intentionality is sufficient for mentality. One response to this problem is to lay down further requirements for intentionality. For example, it may be said that we have intentionality only where we have such phenomena as failure of
substitution or existential presupposition. I consider a variety of
such requirements for intentionality. I argue they either fail to exclude all non-mental phenomena or are so demanding that they ground new, serious
challenges to the claim that qualitative states of mind are
intentional.
Intentionality is the mind’s capacity to direct itself on things. Mental states like thoughts, beliefs, desires, hopes (and others) exhibit intentionality in the sense that they are always directed on, or at, something: if you hope, believe or desire, you must hope, believe or desire something. Hope, belief, desire and any other mental state which is directed at something, are known as intentional states. Intentionality in this sense has only a peripheral connection to the ordinary ideas of intention and intending. An intention to do something is an intentional state, since one cannot intend without intending something; but intentions are only one of many kinds of intentional mental states. The terminology of intentionality derives from the scholastic philosophy of the Middle Ages, and was revived by Brentano in 1874. Brentano characterized intentionality in terms of the mind’s direction upon an object, and emphasized that the object need not exist. He also claimed that it is the intentionality of mental phenomena that distinguishes them from physical phenomena. These ideas of Brentano’s provide the background to twentieth-century discussions of intentionality, in both the phenomenological and analytic traditions. Among these discussions, we can distinguish two general projects. The first is to characterize the essential features of intentionality. For example, is intentionality a relation? If it is, what does it relate, if the object of an intentional state need not exist in order to be thought about? The second is to explain how intentionality can occur in the natural world. How can..
