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.

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

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.).

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.
