This dissertation is a philosophical investigation of irrationality. The aim is to provide a conceptual basis for understanding various forms of irrationality, such as psychosis, neurosis, self-deception, repression, and weak-willed behavior. There are six main chapters, focusing on different phenomena, and touching on several fields of inquiry, including moral psychology, value theory, philosophy of mind, philosophy of language, philosophy of science and psychoanalytic theory. The first two chapters are broad in scope, discussing the relation of philosophy to clinical psychology, and the very possibility of the existence of irrationality. The subsequent four chapters explore the particular topics of the disunity of self, unconscious mental states, self-deception, and weakness of will. There is no single overriding thesis being argued for here, but the general theme is that it is possible to understand irrationality in detail, and that the forms of irrationality that we are capable of understanding include extreme ones that many thinkers have deemed conceptually or logically impossible. Chapter One argues for the importance of the interrelation of philosophy and clinical psychology. Chapter Two argues against the necessity of charitable assumptions of rationality in interpreting the language or behavior of others. Chapter Three discusses the various ways in which the disunity of persons have been conceptualized, and argues that homuncularism often confuses different levels of talking about people. Chapter Four argues for a strong ontology of unconscious mental states and processes, giving them equal status to conscious mentality. Chapter Five argues against several so-called 'paradoxes of self-deception' and clears the way for the possibility of intentional self-deception. Finally, in Chapter Six a standard conception of the distinction between valuing and desiring is examined and found wanting. A new model of the nature of valuing is proposed, drawing on Gestalt psychology. On this view, most weak-willed behavior involves not a divergence between what is desired and what is valued at the time, but rather a change in the person's values. If there are occasions where what is valued differs from what is desired, they are rare and demand a special explanation

Stephens and Grahamset themselves an apparently modest task, to understand why people who experience alien voices and inserted thoughts do not believe that they themselves are the source of these experiences. However, it soon becomes clear that there are many connected issues here. In eight short chapters, they address the phenomenology and ontology of consciousness, the phenomenology of alien voices, inserted thoughts, obsessive-compulsive thoughts and feelings, and other cases of unusual experience often associated with psychopathology, including brief discussion of multiple personality disorder. They survey some of the main empirical explanations of the phenomenology, set out the shortcomings of these theories, and end by proposing their own schematic account.

Gold & Stoljar's target article is important because it shows the limitations of neurobiological theories of the mind more powerfully than previous philosophical criticisms, especially those that focus on the subjective nature of experience and those that use considerations from philosophy of language to argue for the holism of the mental. They use less controversial assumptions and clearer arguments, the conclusions of which are applicable to the whole of neuroscience. Their conclusions can be applied to psychiatry to argue that, contrary to many researchers' assumptions, the approaches to both understanding and treating mental disorders must be interdisciplinary.

Exactly when Philosophy of Psychiatry started as a subfield of Philosophy is hard to say. There are several different estimates of how old psychiatry itself is, from one hundred to three hundred years, and of course there has been discussion and treatment of mental illness for at least a couple of thousand years. A host of issues which could count as belonging to the field have been discussed just within the last hundred years. For instance, a large literature on the philosophy of psychoanalysis dates back to the beginning of the century, and in the last thirty years there has been discussion of amnesia and multiple personality in the philosophy of mind, bioethical debate about involuntary hospitalization and the ability of the mentally ill to give informed consent to drug trials, and recent continental philosophy has shown much interest in madness, civilization, capitalism and schizophrenia. However, I suggest that Philosophy of Psychiatry reached a sense of itself as a separate field only in the 1990s. In this time, it has gained its own association, journal, and a book series with a prestigious press. I refer to the American Association for Philosophy and Psychiatry, the associated journal, Philosophy, Psychiatry, and Psychology, and the MIT Press series, Philosophical Psychopathology: Disorders of Mind, edited by Owen Flanagan and George Graham. Jennifer Radden's Divided Minds and Successive Selves is the first book in that series

There is much to admire in Michelle Ciurria’s provocative approach to ascribing moral responsibility. Her work is detailed and spells out explicitly her methodological assumptions. In this commentary, my main focus is on the methodological assumptions she makes. Ciurria’s arguments often depend on our reactions to actual cases and thought experiments. She takes it for granted that we need a theory that matches certain of our intuitions. This is not an unreasonable way to proceed. We definitely need a good reason if we are going to adopt a theory that does not fit with well-established moral intuitions. Nevertheless, we need to be cautious in using these cases to guide our theory choice, especially when our ..
