In opposition to phenomenology and other currents of recent philosophy, Farber holds that the progress of science and the accumulation of human experience furnish a foundation on which philosophy can safely build, and which it is a waste of time to question. Among the basic truths are.

Definitions are traditionally seen as abbreviations, as tools for notational convenience that do not increase inferential power. From a Philosophy of Mathematical Practice point of view, however, there is much more to definitions. For example, definitions can play a role in problem solving, definitions can contribute to understanding, sometimes equivalent definitions are appreciated differently, and so on. This chapter reviews the literature on definitions and (to a certain extent) concepts in mathematical practice. It is structured according to four themes through (...) which definitions (and concepts) in mathematical practice have been studied. These themes concern (1) the nature of definitions, (2) whether and how concepts evolve, (3) definitions and concepts from a communal perspective, and (4) different values relating to definitions and concepts.

In the philosophy of mathematical practice, the aim is to understand the various aspects of this practice. Even though definitions are a central element of mathematical practice, the study of this aspect of mathematical practice is still in its infancy. In particular, there is little empirical evidence to substantiate claims about definitions in practice. In this article, we address this gap by reporting on an empirical investigation on how mathematicians create definitions and which roles and properties they attribute to them. (...) On the basis of interviews with thirteen research mathematicians, we provide a broad range of relevant aspects of definitions. In particular, we address various roles of definitions and show that definitions are not just a product of mathematical factors, but also of social and contingent factors. Furthermore, we provide concrete examples of how mathematicians interact and think about definition. This broad empirical basis with a variety of examples provides an optimal starting point for future investigations into definitions in mathematical practice. (shrink)

Papers presented at an annual inter-disciplinary seminar held to facilitate the 60th birthday of Kalarikkal Poulose Aleaz, b. 1947, theologist from Kerala, India during 20-21 September 2007.

Since James defined emotion as consciousness of bodily reactions and Cannon and others detailed the nature of these reactions, there has been an increasing tendency among behaviorists to equate emotions with visceral reactions and to neglect some of the genetic and adaptive aspects of emotion which had been discussed by Darwin.

This is a discussion of the claim by certain recent philosophers to have established universal human abilities and disabilities on "logical" grounds, or as a priori necessary. These traits would be independent of empirical conditions, and not of the sort which could be disproved by psychology which, accordingly, would share its field with the a priori philosopher. The author agues, using a series of examples, that these supposed traits do, or could, vary with empirical conditions, and that it is unlikely (...) that in this psychological area there is any good alternative to inductive methods.

What is disappointing of course is not the dispersion of psychology into so many diverse subjects, but their apparent lack of relation to a central core of laws and theories. The topics of psychology, such as sensation, perception, cognition and emotion, which are treated in the first section of the present book, do not appear to constitute a general base for the branches of psychology, for clinical psychology, nor for the so-called borderland subjects. The branch--Animal and Comparative Psychology--does not carry (...) over from general psychology a basic theory of learning, which it then adapts or applies to its own special field. On the contrary, contemporary theory of learning, or rather theories, have been largely evolved within this branch. Similarly, Psychometrics, Child Psychology, and Applied and Social Psychology have, to a great extent, developed their own principles and methods. (shrink)
