This is a philosophical study of concepts that are vital to the conduct of science: namely, dispositional concepts such as force in physics, solubility in chemistry, biological fitness, and psychological traits. By offering a radical and novel interpretation of such concepts, this project has the potential to influence the future development of Australian science. Moreover, dispositions are crucial to understanding our distinctively human perspective on the world. The abilities to predict, reason, communicate meanings, and to act intentionally all involve dispositional states. This project addresses the fundamental nature of such states, and will thus be of significance to anyone who hopes to understand these distinctively human phenomena.Read moreRead less
