Turning biology to life: some reflections


 This essay presents various reflections on living systems, what they are and how they evolve, prompted by editing Teleonomy in Living Systems (a special issue of the Biological Journal of the Linnean Society). Conclusions include the suggestion that the linked notions of teleonomy and agency represent fundamental properties of matter that become apparent only when organized in the way that we consider to be that of a living system. As such, they are factors that form part of the intrinsic ‘a priori’ of living systems, as they evolve in form through space and time. Biology, the science of life and living systems, needs to be ‘biological’ if it is to be anything at all. Understanding the role of teleonomy (internal, inherent goal-seeking) will always play a necessary part in this endeavour: teleonomy represents one of the fundamental properties of living systems.
