Information is the fuel of cognition. At its most basic level, information is a matter of structures interacting under laws. The notion of information thus reflects the (relational) fact that a structure is created by the impact of another structure. The impacted structure is an encoding, in some concrete form, of the interaction with the impacting structure. Information is, essentially, the structural trace in some system of an interaction with another system; it is also, as a consequence, the structural fuel which drives the impacted system's subsequent processes and behavior. Information takes various forms because the world has many levels of compositional and functional complexity, under different constraints. The key constraints that matter in the understanding of information are natural patterns of organization, or types, and systematic correlations among types, or laws. These level- sensitive constraints, in the form of types and laws, shape the very form in which information is tokened in some structure, that is, the very form in which it is encoded. As a result, the information-producing interactions bring about different sorts of structures, with various sorts of causal effects and functions, whence so many ways in which information is coded and utilized.

Many philosophers and a few psychologists think that we understand our own minds before we understand those of others. Most developmental psychologists think that children understand their own minds at about the same time they understand other minds, by using the same cognitive abilities. I disagree with both views. I think that children understand other minds before they understand their own. Their self-understanding depends on some cognitive abilities that develop later than, and independently of, the abilities involved in understanding other minds. This is the general theme of this chapter.

Communication by shared meaning, themastery of word semantics,metarepresentation and metamentation aremental abilities, uniquely human, that share a sense ofintentionality or reference. The latteris developed by a naive psychology or interpretation – acompetence dedicated to representingintentional relations between conspecifics and the world. Theidea that interpretation builds new mentalabilities around a sense of reference is based on three linesof analysis – conceptual, psychological andevolutionary. The conceptual analysis reveals that a senseof reference is at the heart of the abilitiesin question. Psychological data track tight developmentalcorrelations between interpretation and theabilities it designs. Finally, an evolutionary hypothesislooks at why interpretation designed thosenew abilities around a sense of reference.

What is it that one thinks or believes when one thinks or believes something? A mental formula? A sentence in some natural language? Its truth conditions? Or perhaps an abstract proposition? The current story of content is fairly ecumenical. It says that a number of aspects, some mental, other semantic, go into our understanding of content. Yet the current story is incomplete. It leaves out a very important aspect of content, one which I call incremental information. It is information in a specific format, information as a limited or local increment, structured by a number of underlying parameters. It is in the form of such increments that information drives cognition and behavior. This is why, perhaps of all aspects of content, it is incremental information which matters most when we want to understand cognitive attitudes and performances. This in turn must have an impact on our philosophical notions of content, propositional attitudes, inference, justification and knowledge.

The aim of this series is to inform both professional philosophers and a larger readership (of social and natural scientists, methodologists, mathematicians, students, teachers, publishers, etc. ) about what is going on, who's who, and who does what in contemporary philosophy and logic. PROFILES is designed to present the research activity and the results of already outstanding personalities and schools and of newly emerging ones in the various fields of philosophy and logic. There are many Festschrift volumes dedicated to various philosophers. There is the celebrated Library of Living Philosophers edited by P. A. Schilpp whose format influenced the present enterprise. Still they can only cover very little of the contemporary philosophical scene. Faced with a tremendous expansion of philosophical information and with an almost frightening division of labor and increasing specialization we need systematic and regular ways of keeping track of what happens in the profession. PROFILES is intended to perform such a function. Each volume is devoted to one or several philosophers whose views and results are presented and discussed. The profiled philosopher(s) will summarize and review his (their) own work in the main fields of significant contribution. This work will be discussed and evaluated by invited contributors. Relevant his to rial and/or biographical data, an up-to-date bibliography with short abstracts of the most important works and, whenever possible, references to significant reviews and discussion will also be included.

Aside from brute force, there are several philosophically respectable ways of eliminating the mental. In recent years the most popular elimination strategy has been directed against our common sense or folk psychological understanding of the mental. The strategy goes by the name of eliminative materialism (or eliminativism, in short). The motivation behind this strategy seems to be the following. If common sense psychology can be construed as the principled theory of the mental, whose vocabulary and principles implicitly define what counts as mental, then eliminating the theory is eliminating its subject matter. If the theory is shown to be false, then its subject matter does not exist. If, in other words, common sense psychology can be shown to describe and explain nothing real in human cognition, then the mental itself is a fiction.

There is a wide and puzzleful gap between the child’s mastery of first- and recursive or higher-order attributions of attitudes, measured not only in years but also in the cognitive resources involved. Some accounts explain the gap in terms of the maturation of the competencies involved, others invoke the slow development of enabling resources, such as short-term memory, the syntax of sentence embedding or sequential reasoning. All these accounts assume a continuity of competence between first- and higher-order attributions. I disagree and argue, with psychological and neuroscientific support, that there are two distinct (though developmentally overlapping and interacting) competencies, one metaintentional and the other metarepresentational. I focus below on the former and argue that it is egocentric, situated, nonpropositional and thus intrinsically limited to first-order attributions, even when all the enabling resources are in place.

The local justification of beliefs and hypotheses has recently become a major concern for epistemologists and philosophers of induction. As such, the problem of local justification is not entirely new. Most pragmatists had addressed themselves to it, and so did, to some extent, many classical inductivists in the Bacon-Whewell-Mill tradition. In the last few decades, however, the use of logic and semantics, probability calculus, statistical methods, and decision-theoretic concepts in the reconstruction of in ductive inference has revealed some important technical respects in which inductive justification can be local: the choice of a language, with its syntactic and semantic features, the relativity of probabilistic evalua tions to an initial body of evidence or background knowledge and to an agent's utilities and preferences, etc. Some paradoxes and difficulties encountered by purely formal accounts of inductive justification, the erosion of the once dominant empiricist position, which most approaches to induction took for granted, and the increasing challenge of noninduc tivist epistemolgies have underscored the need of accounting for the methodological problems of applying inductive logic to real life contexts, particularly in science. As a result, in the late fifties and sixties, several related developments pointed to a new, local approach to inductive justification.

A distinguished wise man, Emil Cioran, with whom I share a country of birth and the thought that follows, said once that the two most interesting things in life are gossip and metaphysics. I can hardly think of a more self evident and enjoyable truth, if wisely construed. This volume combines the two pleasures, for it is an exercise in the metaphysics of wise gossip, of how we make sense of each other, and how, as a result we interpret, explain, rationalize and evaluate our representations and actions. The body of wisdom which allows us to do all this is currently currently called folk or common sense psychology. I will also call it psychofolklore or the folklore of the mind.
