Challenging, with several powerful arguments, some of our deepest beliefs about rationality, morality, and personal identity, Parfit claims that we have a false view about our own nature. It is often rational to act against our own best interersts, he argues, and most of us have moral views that are self-defeating. We often act wrongly, although we know there will be no one with serious grounds for complaint, and when we consider future generations it is very hard to avoid conclusions (...) that most of us will find very disturbing.

This paper is about the neglected question of what sort of things we are metaphysically speaking. It is different from the mind-body problem and from familiar questions of personal identity. After explaining what the question means and how it differs from others, the paper tries to show how difficult it is to give a satisfying answer.

Humans are closely coupled with their environments. They rely on being ‘embedded’ to help coordinate the use of their internal cognitive resources with external tools and resources. Consequently, everyday cognition, even cognition in the absence of others, may be viewed as partially distributed. As cognitive scientists our job is to discover and explain the principles governing this distribution: principles of coordination, externalization, and interaction. As designers our job is to use these principles, especially if they can be converted to metrics, (...) in order to invent and evaluate candidate designs. After discussing a few principles of interaction and embedding I discuss the usefulness of a range of metrics derived from economics, computational complexity, and psychology. (shrink)

The goal of this paper is to develop a systematic taxonomy of cognitive artifacts, i.e., human-made, physical objects that functionally contribute to performing a cognitive task. First, I identify the target domain by conceptualizing the category of cognitive artifacts as a functional kind: a kind of artifact that is defined purely by its function. Next, on the basis of their informational properties, I develop a set of related subcategories in which cognitive artifacts with similar properties can be grouped. In this (...) taxonomy, I distinguish between three taxa, those of family, genus, and species. The family includes all cognitive artifacts without further specifying their informational properties. Two genera are then distinguished: representational and non-representational (or ecological) cognitive artifacts. These genera are further divided into species. In case of representational artifacts, these species are iconic, indexical, or symbolic. In case of ecological artifacts, these species are spatial or structural. Within species, token artifacts are identified. The proposed taxonomy is an important first step towards a better understanding of the range and variety of cognitive artifacts and is a helpful point of departure, both for conceptualizing how different artifacts augment or impair cognitive performance and how they transform and are integrated into our cognitive system and practices.

In this paper I discuss the question of what it means to say that a property is socially constructed. I focus on an influential project that many social constructivists are engaged in, namely, arguing against the inevitability of a trait, and I examine several recent characterizations of social construction, with the aim of assessing which one is more suited to the task.

A research study that obtained questionnaire data via mobile communications from 3,267 residents of all 50 US states illustrates how personality capture can be accomplished in a manner suitable for later emulation inside a virtual world or comparable computer system by means of artificial intelligence agents calibrated to match the personality profiles of specific people. This was the most recent step in a research project that had already developed methods for computer administration of massive questionnaires, and it focused on one (...) of the most prominent models of personality, the so-called Big Five dimensions. The key innovation of mobile data collection will allow efficient personality capture at low cost in effort to the individual, and thus with greater ultimate accuracy because of the very large number of diverse measures that can be obtained. Factor analysis of the data shows how it is possible to develop a flexible system for aggregation of measures that can be adapted to emulation across a changing array of environments. (shrink)

Especially troublesome in this dispute is the status of the natural sciences, and this is where Hacking finds some of his most telling cases, from the conflict ...

In Supersizing the Mind, Andy Clark argues that the human mind is not bound inside the head but extends into body and environment.

Social “construction,” “constructionism” and “constructivism” are terms in wide use in the humanities and social sciences, and are applied to a diverse range of objects including the emotions, gender, race, sex, homo- and hetero-sexuality, mental illness, technology, quarks, facts, reality, and truth. This sort of terminology plays a number of different roles in different discourses, only some of which are philosophically interesting, and fewer of which admit of a “naturalistic” approach—an approach that treats science as a central and successful (if (...) sometimes fallible) source of knowledge about the world. If there is any core idea of social constructionism, it is that some object or objects are caused or controlled by social or cultural factors rather than natural factors, and if there is any core motivation of such research, it is the aim of showing that such objects are or were under our control: they could be, or might have been, otherwise.
