The teleological modal profile and subjunctive background of organic generation and growth

Formal methods for representing the characteristic features of organic development and growth make it possible to map the large-scale teleological structure of organic activity. This provides a basis for semantically evaluating, or providing a theory of meaning for, talk of organic activity as purposive. For the processes of organic generation and growth are subjunctively robust under a variety of influences characteristic for the kind or species in question, and these subjunctive conditions can be displayed in a two-dimensional array. After motivating and introducing this array, I use its two dimensions to partially account for features of the purposiveness characterizing two sets of exemplars of the plant and animal kingdoms: ferns and cacti, and cheetah and gazelle. The result is a formal framework for interpreting talk of organic activity as purposive, able to be adapted to a range of research traditions in the philosophy of language and the philosophy of biology.
