Syllabus | Phil 410 - Constructive approaches to the emergence and evolution of life - Fall 2003
751-7337 | email@example.com
Biweekly lecture/conference: Tu/Th 2:40-4:00.
Occasional evening lab/conferences will be scheduled during the term.
A 300-level philosophy course or permission of the instructor.
Philosophy is concerned with the essential nature of the most fundamental aspects of reality, such as life and mind. Philosophy traditionally relies on a priori thought experiments and conceptual analyses, but these methods have limitations. A priori thought experiments yield uncertain and inconclusive results when directed to complex systems. And conceptual analysis of complex phenomena sometimes reveals more about the quirks of our contingent conceptual schemes than about the nature of actual phenomena.
The course is an introduction to constructive methods for understanding the nature of real complex systems. The focus will be on natural systems that are alive and that emerge and evolve spontaneously in the material world. The constructive methods covered include cellular automata, random trees, genetic algorithms, and agent- or individual-based (or botton-up) models of evolution. These methods are constructive in the sense that they explain phenomena by synthesizing instances of them. Constructive methods typically are implemented as computer simulations, and they can be viewed as computational analogs of traditional thought experiments in philosophy.
The course has two parts. The first part is an introduction to important constructive models of living phenomena. Computer programming is not required, but all students will do computer experiments. The second part of the course explores how constructive methods can be applied to understand the emergence and evolution of life.
