Some epistemological issues in physics and biology: Robert Rosen
I am very pleased to have been invited to contribute to this Festschrift in honor of David Bohm. Although I have never personally met or corresponded with Dr Bohm, his writings were well known to me since I was a graduate student. Moreover, the epistemological struggles into which he has been drawn as a theoretical physicist have their counterpart in epistemological struggles into which I have been drawn as a theoretical biologist. I would like to address some of these latter in the considerations which follow, especially as they bear on the material basis of biological processes.
