Minding Disorder: Philosophys role Address issues deemed to be meta-scientific Is psychiatry a science? Are there laws of psychiatry? Are mental disorders natural kinds? Or social kinds? Help tidy-up potential conceptual confusions What is a mental disorder? Categorization of disorders?
Disordered Minds: Psychiatrys role The self Belief states Perception & Cognition Human nature Cognitive architecture
What is philosophy of psychiatry? Applied philosophy of science Philosophy of physics Philosophy of biology Philosophy of social sciences Philosophy of psychology philosophy of mind
A branch of psychology? A branch of medicine? Is it a science? What demarcates science from non-science?
It is, at the least, reasonable to think that psychiatry is a science. Of course, whether it is will depend on the nature of the phenomenonmental disordersthat psychiatry is concerned with. What is a mental disorder?
Schizophrenia Bipolar Disorder Depression OCD Autism Alzheimers Capgras Syndrome Cotard syndrome Alcohol/drug addiction Depression Sociopathy ADHD Cortical Blindness Drapetomania What do all these things have in common?
Mental disorder is the behavior resulting from an underlying cause (the unconscious) Unconscious mechanisms drive conscious experiences and behavior and can be revealed and rendered intelligible by the psychoanalytic technique of interpretation.
Thomas Szasz Mental disorders are not true disorders because there are no accompanying lesions Mental disorder as problems in living Diagnosis as a means of power and control *Note: As far as I know, Szasz is not a scientologist!
Mental disorder has a normative as well as an objective component Harm Conditions Dysfunctioning mental mechanism
If psychiatry is a science, then the categories it investigates should support inductive generalizations. We want to be able to investigate a few instances of a category and project what we learn to all members of the category. Only certain categories/classes support scientifically interesting inductive generalizationsnatural kinds.
What is a natural kind? 1. A Natural kind is a class that has a property cluster that result from some causal mechanism(s). 2. The mechanism(s) which causally sustain the relevant property cluster can be considered the defining feature of a natural kind.
Psychiatry ought to only investigate mental disorders that are natural kinds. DSM-IV categories of mental disorder are symptom basedcategories are based on symptom-clusters. These categories are often treated as though they are natural kinds, kinds that should be scientifically investigated and that possess underlying causal unity.
The problem: Many DSM IV categories are probably not natural kinds!!! Whats the big deal? Investigating non-natural kinds may stall progress.
DSM-IV: Delusion A false belief The belief is based on incorrect inference about external reality Entrenched and rigid. The belief is not one ordinarily accepted by other members of the person's culture or subculture (e.g., it is not an article of religious faith).
1. Some delusions are probably caused by motivational factors employed for coping. e.g., erotomania 2. Some delusions are likely caused by cognitive/perceptual impairments. e.g., Capgras *Suggests various causal mechanisms.
1. Bottom-up: abnormal experience that then modifies belief system. 2. Top-down: start with modified beliefs that give rise to strange experiences. *Suggests various causal mechanisms.
Origins: Division of emotional labor Gives rise to multiple personalities? Fictive selves vs. Real Selves Are multiple personalities the same as multiple selves? Do neurotypicals only have one self? Is it a Fictive self
What is the relation between delusions and beliefs? Delusions do not integrate well and are not sensitive to updating in the face of new evidence. Does this suggest that delusions are not beliefs? Or does it suggest our previous notions of belief are too strongi.e., no account of beliefs consistent with empirical data suggests the strict conditions that are often imposed on beliefs.
If most disorders are just deviations from the norm along a continuum then we learn something about human nature. Most people have multiple personalities. Most people have obsessive-compulsive tendencies in certain domains. Most people have delusions. Most people experience depression. We need to keep these facts in mind if philosophical claims hinge on alleged features of human nature (i.e., descriptive ethics, theories of rationality).
How tightly linked are cognition and perception? Top-down accounts of delusions suggest that cognition can influence perception. How much influence can the physiological component of depression have on agency and cognition? Do depressives perceive, or conceive, the world differently What can we learn about the content of mental states from mental disorders such as delusions?
Do mental disorders tell us anything about the cognitive architecture of the human mind-brain? Can we infer dedicated modules from observed mental disorders? Can we infer that certain cognitive processes are not modular; rather, that they are domain general?

Delusions are (probably) not a natural kind: What Samuels missed about realization, Bryan Miller In Delusions as a natural kind Richard Samuels argues contrary to theorists such as Peter Zachar (2000) and Nassir Ghaemi (2004) that delusions probably do constitute a natural kind. Samuels supports his claim, the natural kind thesis (hereafter, NK thesis), by showing that several objections to it are mistaken. One of the strongest objections that Samuels must face is the heterogeneity objection, the claim that the NK thesis is false because delusions are realized by a number of heterogeneous neural and/or cognitive states. Samuels response to this objection notes that this only shows that delusions are multiply realizable and that this fact is consistent with and supportive of the NK thesis. In this paper, I argue that Samuels response to the heterogeneity objections fails to support the NK thesis insofar as it employs a form of realization that does not give rise to natural kinds. I conclude by remarking on how the failure to secure the natural kind status of delusions might be problematic for a special case of delusionsnamely, religious delusions. Dworkin on the Moral Psychology of Abortion, Jonathon Hricko In his book Lifes Dominion, Ronald Dworkin argues that, though defenders of the pro-life position may say that they object to abortion because they believe that it violates the rights and interests of the fetus, they actually object to it because they believe that it violates the intrinsic value of the fetus. Dworkin attempts to reach this conclusion by arguing that the former belief is incoherent. I will draw an analogy between the abortion debate and the conjunction fallacy in order to argue that Dworkin cannot reach his conclusion by means of the arguments he gives. The fact that a belief is incoherent is no reason to conclude that people do not hold that belief. Just as the probability rankings that people assign to a set of statements is an empirical issue, so is what people think about abortion, and so an empirical investigation is necessary to determine whether Dworkins conclusion is correct.
Religion, Rationality, and Altruism, John Waterman Religion is puzzling from an evolutionary perspective. Religious ritual and belief have clear adaptive costs in time and effort, but they don't have clear compensating benefits. By any right, natural selection should have eliminated them long ago. Instead we find religion is a human universal. How should we explain this? An age old, if now unpopular, view explains that religions worth derives from promoting morality. Costly Signaling Theory, an adaptationist approach gaining currency among cognitive scientists of religion, updates this view. It argues religious beliefs and rituals are adaptations integral to the evolution of human altruism. The theory claims the adaptive benefits of religion accrue by mitigating the threat narrow self-interest poses to cooperative behavior. In this essay I argue that Costly Signaling Theory fails as an explanation of the evolution of cooperation in populations with unrelated individuals. Using the framework of evolutionary game theory, I show that religious belief and religious ritual are neither necessary nor sufficient for eliminating the underlying adaptive instability of cooperative behavior. I conclude with a discussion of the evolutionary relationship between religion and morality, and by considering a pending question for both adaptationist and spandrelist theories of religious cognition. Between Adaptations and Spandrels: Cognitive science and evolutionary psychology of religion, Derek Leben Many psychologists, anthropologists, and biologists currently attempt to explain religion as not only a biological-cognitive product, but as an evolutionary adaptation. This paper will discuss the adaptationist argument as well as the supposed alternative, that religion is a useless by-product of other cognitive systems (spandrelism). It will be argued that the adaptationist argument is not effective, due to a failure to distinguish beneficial uses from proper evolutionary functions, as well as a much wider variety of evolutionary causes than simply an adaptation or spandrel (kluge, exaptation, co-opted mechanism). Other cases such as language and moral appraisal will also be considered for comparison.

Which account of mental disorder seems most correct? Why? If there is essentially a normative component to mental disorder, does this threaten the status of psychiatry as a science? Can mental disorder ever be valuable?
