Although natural philosophers have long been interested in individuality, it has been of interest to contemporary philosophers of biology because of its role in different aspects of evolutionary biology. These debates include whether species are individuals or classes, what counts as a unit of selection, and how transitions in individuality occur evolutionarily. Philosophical analyses are often conducted in terms of metaphysics (“what is an individual?”), rather than epistemology (“how can and do researchers conceptualize individuals so as to address some of (...) their scientific goals?”). We review several philosophical distinctions in order to shift attention from metaphysics to epistemology. Many controversies involve epistemological differences rather than metaphysical disagreement. This implies that a pluralist stance about individuality in biology is warranted and has metaphysical consequences because the pluralism emerges from the diversity of scientific interests that investigate the complexity of living phenomena.

The guiding idea behind formalism is that mathematics is not a body of propositions representing an abstract sector of reality but is much more akin to a game, bringing with it no more commitment to an ontology of objects or properties than ludo or chess. This idea has some intuitive plausibility: consider the tyro toiling at multiplication tables or the student using a standard algorithm for differentiating or integrating a function. It also corresponds to some aspects of the practice of (...) advanced mathematicians in some periods—for example, the treatment of imaginary numbers for some time after Bombelli's introduction of them, and perhaps the attitude of some contemporary mathematicians towards the higher flights of set theory. Finally, it is often the position to which philosophically naïve respondents will gesture towards, when pestered by questions as to the nature of mathematics. (shrink)

Drawing upon ancient Hindu philosophy, the author explores the human psyche and the importance of personal identity.

In the last few years, off-line simulation has become an increasingly important alternative to standard explanations in cognitive science. The contemporary debate began with Gordon (1986) and Goldman's (1989) off-line simulation account of our capacity to predict behavior. On their view, in predicting people's behavior we take our own decision making system `off line' and supply it with the `pretend' beliefs and desires of the person whose behavior we are trying to predict; we then let the decision maker reach a (...) decision on the basis of these pretend inputs. Figure 1 offers a `boxological' version of the off-line simulation theory of behavior prediction.(1). (shrink)

The ubiquity of top-down causal explanations within and across the sciences is prima facie evidence for the existence of top-down causation. Much debate has been focused on whether top-down causation is coherent or in conflict with reductionism. Less attention has been given to the question of whether these representations of hierarchical relations pick out a single, common hierarchy. A negative answer to this question undermines a commonplace view that the world is divided into stratified ‘levels’ of organization and suggests that (...) attributions of causal responsibility in different hierarchical representations may not have a meaningful basis for comparison. Representations used in top-down and bottom-up explanations are primarily ‘local’ and tied to distinct domains of science, illustrated here by protein structure and folding. This locality suggests that no single metaphysical account of hierarchy for causal relations to obtain within emerges from the epistemology of scientific explanation. Instead, a pluralist perspective is recommended—many different kinds of top-down causation (explanation) can exist alongside many different kinds of bottom-up causation (explanation). Pluralism makes plausible why different senses of top-down causation can be coherent and not in conflict with reductionism, thereby illustrating a productive interface between philosophical analysis and scientific inquiry.

Idealization is a reasoning strategy that biologists use to describe, model and explain that purposefully departs from features known to be present in nature. Similar to other strategies of scientific reasoning, idealization combines distinctive strengths alongside of latent weaknesses. The study of ontogeny in model organisms is usually executed by establishing a set of normal stages for embryonic development, which enables researchers in different laboratory contexts to have standardized comparisons of experimental results. Normal stages are a form of idealization because (...) they intentionally ignore known variation in development, including variation associated with phenotypic plasticity (e.g. via strict control of environmental variables). This is a tension between the phenomenon of plasticity and the practice of staging that has consequences for evolutionary developmental investigation because variation is conceptually removed as a part of rendering model organisms experimentally tractable. Two compensatory tactics for mitigating these consequences are discussed: employing a diversity of model organisms and adopting alternative periodizations. (shrink)

This book is available either individually, or as part of the specially-priced Arguments of the Philosphers Collection.

Psychological and philosophical perspectives are employed in an exploration of the reasons particular individuals experience an activity as personally expressive while others may find the same activity neutral or even aversive. The relationships between personal expressiveness and intrinsic motivation, flow, and self-actualization are considered. The construct of personal expressiveness is shown to have its roots in eudaimonistic philosophy. Living in a manner consistent with one's daimon or "true self" gives rise to a cognitive-affective state labeled "eudaimonia" that is distinguishable from (...) hedonic enjoyment. A personally expressive personality pattern is described integrating concepts from diverse theories including a sense of personal identity, self-actualization, an internal locus of control, and principled moral reasoning. A series of empirical investigations is proposed to test the theoretical concepts of personal expressiveness advanced. (shrink)

Philosophers and psychologists have recently been focusing on the important question of how positive character traits are developed. Within philosophy, these positive character traits are referred to as virtues. In this chapter, I examine one intuitively appealing proposal concerning virtue development - the idea that the path to moral virtue can begin with the experience of admiration for a moral exemplar. My aim is to provide a model of how this process might work by identifying the different stages it would (...) involve. I then highlight three ways in which admiration might nevertheless fail to result in the development of moral virtue. It is hoped that providing this model, and identifying the potential problems, will be helpful for those interested in virtue education. (shrink)

Providing an illuminating and informed introduction to central philosophical issues, concepts and perspectives in the core fields of metaphysics, epistemology and philosophical logic, the _Dictionary_ takes the most common terms and notions and clarifies what they mean to the philosopher and what sort of problems the philosopher finds associated with them. Thoroughly revised and updated, the bibliographies supply core reading lists, and each entry uses extensive cross referencing to related themes and concepts to provide a greater sense of access, control (...) and comprehension. The _Dictionary_ will also provide those working in proximate fields with an understanding of areas of overlapping interest, concepts of common applicability and the full range and diversity of philosophical analysis and insight.
