Design Principles in Biology – A Philosophical Analysis
Info about event
To what extent is it productive to investigate living systems as if they were designed? Why do some biologists attempt to identify general and rather abstract principles of biological organization? These are among the questions addressed in Sara M. E. Green’s PhD project. During her studies, Sara M. E. Green has investigated the philosophical implications of research strategies within systems biology, a new interdisciplinary field where researchers draw on mathematical modelling of processes in living systems. The PhD project is a practice-oriented analysis of a research strategy aimed at identifying general principles of living systems. These principles are often considered analogous to design principles in engineering and raise a number of philosophically interesting questions regarding methodologies and explanatory strategies in biology.
While traditional philosophy of science has often considered physics a ‘model-discipline’, modern philosophers of biology have rejected the view that explanations in biology could or should follow the same explanatory scheme that relies on scientific laws. This deflationary view of explanations is motivated by the complexity, variation and contingency of living systems. These features tend to make biological explanations less general – but for that matter not less scientific. Yet, systems biologists have in recent years intensified the search for general principles and law-like regularities. This development calls for an analysis of whether (and how) a more abstract approach to living systems can be a fruitful strategy in biology, and whether this strategy conflicts with the aim of providing detailed explanations of biological mechanisms.
The PhD studies were completed at the Centre for Science Studies, Department of Physics and Astronomy, Aarhus University, and during research visits at Egenis, the Centre for the Study for the Life Sciences, University of Exeter, UK, and Department of Philosophy, University of Sydney.
