From Seed to Seed: Material Activities and Vegetable Life in Grew's Philosophy of Botany

In 1682, Nehemiah Grew included An Idea of a Philosophical History of Plants as the first text in his Anatomy of Plants. The former consists of a broad programme to study vegetation from a material standpoint. In addition to the mechanical and chymical investigation of plants, generally supported by microscopic observations—a core methodology of the Royal Society—in the text Grew engaged with some more philosophical and theoretical issues. Still, despite Grew's creditable attempt to produce a coherent and comprehensive science of plants, the absence of a definition of vegetable life has an impact on his ability to understand plants in their own right. For instance, a few questions that emerged as Grew addressed zoophytes and other bodies blurred the line between vegetables and animals. Only in the Cosmologia sacra (1701) did Grew propound a definition of vegetable life with a more complete schema. Is the philosophy of plants a bridge between Grew's works? In this article, I contextualize his philosophical approach, explore the features of his text, and advance the possibility of answering this question positively, although the significant distance between Grew's experimental study of plants in the Anatomy and the physicotheology of the Cosmologia makes a connection between the two texts difficult. In the end, this unbridgeable gulf broadly shaped early modern botanical studies.
