Background

The topic of explanation has been a traditional concern of philosophers of science. Philosophy of biology developed in part out of dissatisfaction with some of the canonical ideas about explanation supplied by philosophy of science. These emphasized the role of formal theory, but explicit theories are notable for their absence from biology. In recent years some philosophers have sought to account for explanation in terms of mechanisms, but this raises the issue of the extent to which biological systems such as cells can be thought of in mechanistic terms. How does the concept of mechanism relate to complexity and emergence, and what part do functional attributions play in biological explanation? I develop a perspective on explanation and understanding that tries to address these questions, in part by looking to findings from cognitive psychology concerning the role of imagination and visual thought. Overall I stress the metaphysically laden nature of biological knowledge.

Aims

The key research questions are
  1. How is explanation in biology to be understood philosophically?
  2. What constraints do the nature of biological systems such as the cell place on their intelligibility?
  3. Do attributions of, for example, mechanism, function, complexity and emergence relate to ontologically robust, objective features of the world beyond our minds, or should they be seen as making sense only in the context of our cognitive or other psychological capacities?

Methods

Study of relevant philosophical and scientific literature; philosophical reflection and analysis.

Policy implications

This project will assist philosophers, scientists and policy-makers in understanding how bio-ontological issues intersect with knowledge-making practices in contemporary bioscience.
