Experiments are actions, performed in order to gain information. Like other acts, there are virtues of performing them well. I discuss one virtue of experimentation, that of knowing how to trade its information-gaining potential against other goods.

This is a reply to de Sousa's 'Emotional Truth', in which he argues that emotions can be objective, as propositional truths are. I say that it is better to distinguish between truth and accuracy, and agree with de Sousa to the extent of arguing that emotions can be more or less accurate, that is, based on the facts as they are.

I praise Franklin's full descriptions of important and exemplary experiments, and wish that he had said more about why they are exemplary.

I assess Churchland's views on folk psychology and conceptual thinking, with particular emphasis on the connection between these topics.

I relate plural quantification, and predicate logic where predicates do not need a fixed number of argument places, to the part-whole relation. For more on these themes see later work by Boolos, Lewis, and Oliver & Smiley.

I argue that folk psychology does not serve the purpose of facilitating prediction of others' behaviour but if facilitating cooperative action. (See my subsequent book *The Importance of Being Understood*.

I consider Glimcher's claim to have given an account of mental functioning that is at once neurological and decision-theoretical. I am skeptical, but remark on some good ideas of Glimcher's.

I discuss a large number of emotions that are relevant to performance at epistemic tasks. My central concern is the possibility that it is not the emotions that are most relevant to success of these tasks but associated virtues. I present cases in which it does seem to be the emotions rather than the virtues that are doing the work. I end of the paper by mentioning the connections between desirable and undesirable epistemic emotions.

This paper begins with a discussion the role of less-than-admirable epistemic emotions in our respectable, indeed admirable inquiries: nosiness, obsessiveness, wishful thinking, denial, partisanship. The explanation for their desirable effect is Mandevillian: because of the division of epistemic labour individual epistemic vices can lead to shared knowledge. In fact it is sometimes essential to it.

I give models for modal languages in which all individuals are actual.

I compare our idioms for quantifying into belief contexts to our idioms for quantifying into intention contexts. The latter is complicated by the fact that there is always a discrepancy between the action as intended and the action as performed. The article contains - this is written long after it appeared - an early version of a tracking or sensitivity analysis of the relation between a thought and its object.

review of Falzon *Philosophy goes to the Movies*.

We give a general description of a class of contrastive constructions, intended to capture what is common to contrastive knowledge, belief, hope, fear, understanding and other cases where one expresses a propositional attitude in terms of “rather than”. The crucial element is the agent's incapacity to distinguish some possibilities from others. Contrastivity requires a course-graining of the set of possible worlds. As a result, contrastivity will usually cut across logical consequence, so that an agent can have an attitude to p (...) rather than q but not to r rather than q , where r is a logical consequence of p . We relate these ideas to some general issues about thought, such as the question of whether all possibilities that can be distinguished in emotion can be distinguished in belief. (shrink)

I give ways of comparing the disvalue of death and of pain by comparing each to other evils.

I discuss Quine's claim that anyone denying what we now take to be a logical truth would be using logical words in a novel way. I trace this to a confusions between outright denial and failure to assert, and assertion of a negation. (This abstract is written from memory decades after the article.).

review of Mark Crimmins' *Talk about Beliefs*.

I discuss ways in which the linguistic form of mathimatics helps us think mathematically.

I discuss the possibility that there is no intrinsic unity to the capacities which are bundled under the label "folk psychology". Cooperative skills, attributional skills, and predictive skills may be scattered as parts of other non--psychological capacities. I discuss how some forms of social life bring these different skills together. I end with some remarks on how abilities that are not unified in their essential mechanisms may still form a rough practical unity. (Remark: the paper is conjectural. It describes a (...) possibility to take seriously rather than a conclusion of which I am convinced.). (shrink)

I argue that considerations about computational complexity show that all finite agents need characteristics like those that have been called epistemic virtues. The necessity of these virtues follows in part from the nonexistence of shortcuts, or efficient ways of finding shortcuts, to cognitively expensive routines. It follows that agents must possess the capacities – metavirtues –of developing in advance the cognitive virtues they will need when time and memory are at a premium.

I explore the possibility that propositional attitudes are not basic in folk psychology, and that what we really ascribe to people are relations to individuals, those that the apparently propositional contents of beliefs, desires, and other states concern. In particular, the relation between a state and the individuals that it tracks shows how ascription of propositional attitudes could grow out of ascription of relations between people and objects.

The concepts of knowledge and of accomplishment have many similarities. In fact they are duals, in a sense that I explain. Similar issues arise about both of them, deriving from the functions they serve in everyday evaluation of inquiry and action.

Is there such a thing as bounded rationality? I first try to make sense of the question, and then to suggest which of the disambiguated versions might have answers. We need an account of bounded rationality that takes account of detailed contingent facts about the ways in which human beings fail to perform as we might ideally want to. But we should not think in terms of rules or norms which define good responses to an individual's limitations, but rather in (...) terms of desiderata, situations that limited agents can hope to achieve, and corresponding virtues of achieving them. We should not take formal theories defining optimal behavior in watered-down bounded form, even though they can impose enormous computational or cognitive demands. (shrink)

I classify emotions in the family of regret, remorse, and so on, in such a way that it is easy to see how there can be further emotions in this family, for which we happened not to have names in English. I describe some of these emotions.

In natural language we rarely use relation-words with more than three argument places. This paper studies one systematic device, rooted in natural language, by which relations of greater adicity can be expressed. It is based on a higher-order relation between 1-place, 2-place, and 4-place relations (and so on) of which the relation between the positive and comparative degrees of a predicate is a special case. Two formal languages are presented in this connection, one of which represents the language of communication (...) and the other the contextual information against which the first language is interpreted. A semantical theory is described, which treats the two languages in an interdependent way. Logical consequence is non-compact. Connections with issues about vagueness are made. (shrink)

review of Laden's *Reasoning: a social picture* praising the aim and expressing puzzlement at the details,.

In lieu of an abstract, here is a brief excerpt of the content:Philosophy, Psychiatry, & Psychology 12.3 (2005) 257-259 [Access article in PDF] Atrocity, Banality, Self-Deception Adam Morton Keywords evil, self-deception, banality, atrocity, motivation When talking about evil we must make a fundamental choice about how we are to use the term. We may use it as half of the contrast "good versus evil," in which case it covers everything that is not good. That includes moral incompetence, lack (...) of imagination, willingness to follow orders, overreactions, and a host of other reasons why people who do not have personalities that we would call evil do things that are wrong, often very wrong. Call this the weak reading of evil: evil as wrongdoing. Or we may use it with the meaning suggested by "evil person," "really evil act," "the evil lurking in all of us," and other such idioms. If we do this, we focus on a particular class of actions, and the motives and people that produce them, that arouse a particular moral revulsion in us. Call this the strong reading of evil: evil as atrocity (for more on this contrast see Morton [2004] and Card [2002]).Kubarych, following Peck, thinks of evil in the strong way. Most of the time at any rate: Some of the philosophers, such as Kant, that he draws on are thinking of evil in the weak way, and some of his quotations are from the German, where good/bad/evil distinctions are not drawn in the same way as in English. He explores a general explanation of evil that seems to be targeted at the psychology of extremely abhorrent actions. But, I argue, his account is in danger of collapse in either of two directions. Depending on how we interpret Kubarych's account, it could turn out that it describes all wrongdoing as evil, or, making some different choices, it could turn out that there are no really evil people.The strong reading of evil is definitely the most interesting and potentially fruitful. After all, we have no shortage of satisfying explanations of why people lie to get out of unwelcome appointments, steal to support their children or their drug habits, or defraud investors to become rich. But we do feel deeply puzzled by those who commit torture, serial murder, or genocide. We ask of these people not so much "Why did he do it?" as "How could he do it?" We feel the need of a philosophical or psychological theory that can give us even a slight handle of these people and their deeds. There are two risks associated with the project of explaining atrocity, though. The first is the risk of accepting unsatisfactory accounts, just because they purport to explain what we desperately want to understand. The second is the risk of supposing that there is a single explanation when the causes of the phenomenon are in fact too varied. On other topics these two risks have often combined to make people believe what seem to us now to be evident falsehoods. Humans have often for example wanted to know the causes of disease, and as a result have accepted blanket explanations, in terms of [End Page 257] evil spirits or lack of faith, that seem ludicrous to us now that we have a better grasp of the variety of factors that can cause our bodies to misfunction. So before asking naively "Why and how can people do these awful things?" we should ask "Is there a deeper causal unity here, beyond the fact that we react to these acts with horror?"My suspicion is that there is not much unity, that it is asking too much to want a common profile to the psychology of serial killers, or of proponents of genocide, let alone a profile that applies across these and other categories. What we can do, I believe, is describe our concept of evil in such a way that we can leave some parameters to be filled in by a large variety of objective psychological factors. Even this runs the risk that the really relevant factors cannot be forced into the role that the philosophical account requires. In... (shrink)

I point out that internalist conceptions of belief that have become outmoded in the philosophy of mind are still current in epistemology (or at any rate they were in 2003). I explore the consequences of bringing epistemology up to speed with a more contemporary conception of belief.

I argue that the Frankfurtian concept of a person ignored the indexical 'I'.

I discuss Frege's argument - later called the slingshot - that if a construction is extensional and preserves logical equivalence then it is truth-functional. I consider some simple apparent counterexamples and conclude that they are not sentence-embedding in the required way.

I discuss what learned and innate routines of self and other attribution agents need to possess if they are to enter into cooperative arrangements as described game theoretically. I conclude that these are not so different from belief desire psychology as described by philosophers of mind.

I explore how considerations about psychological damage connect with moral theories.

I tried to tease out what Gilbert means by "normative". It isn't obvious. I conclude that assumptions about ideal agents – not just ideal in the sense of error-free but also ideal in the sense of unlimited – and assumptions about ideal placement of oneself in another person's situation, are essential to what he means. I conclude that what he says is very plausible given these assumptions, though they themselves are very problematic. Especially problematic is the idea of an unlimited (...) simulation of a limited agent's perspective. (shrink)

I discuss Goodman's claim that when 'all As are Bs' is a law then the counterfactual 'if a were an A, it would be a B' is tue. I give counterexamples, and link the failure of the connection to the contrast between higher level and lower level laws.

Scale matters in morality, so that different factors occupy us at high and low scales. Different people are needed to be good neighbours in everyday life and moral heroes in crises. There is no reason to believe that the same traits are required for both. So there is no such thing as the all-round good person.

some lighthearted definitions of philosophical terms.

Card argues that we should not give injustice priority over evil. I agree. But I think Card sets us up for some difficult balancings, for example of small evils against middle sized injustices. I suggest some ways of staying off the tightrope.

It is in a way easier to imagine evil actions than we often suppose, but what it is thus relatively easy to do is not what we want to understand about evil. To argue for this conclusion I distin- guish between imagining why someone did something and imagining how they could have done it, and I try to grasp partial understanding, in part by distinguishing different imaginative pers- pectives we can have on an act. When we do this we see (...) an often unnoticed asymmetry: we do not put the same demands on our understanding of wrongdoing as on that of most everyday, morally acceptable, actions. (shrink)

I survey the previous 20 years work on the nature of folk psychology, with particular emphasis on the original debate between theory theorists and simulation theorists, and the positions that have emerged from this debate.

The concepts of knowledge and accomplishment are duals. There are many parallels between them. In this paper I discuss the "AA" thesis, which is dual to the well known KK thesis. The KK thesis claims that if someone knows something, then she knows that she knows it. This is generally thought to be false, and there are powerful reasons for rejecting it. The AA thesis claims that if someone accomplishes something, then she accomplishes that she accomplishes it. I argue that (...) this, too, is false, and that the reasons it is false parallel reasons for the falsity of the KK thesis. (shrink)

Mathematical models provide explanations of limited power of specific aspects of phenomena. One way of articulating their limits here, without denying their essential powers, is in terms of contrastive explanation.
