Abstract

This study examines the botanical and chymical investigations Nehemiah Grew conducted for his magnum opus, The Anatomy of Plants (1682), and explores how they informed his political economic theory, as documented in the unpublished manuscript The Means of a Most Ample Increase of the Wealth and Strength of England (1707). While several scholars have argued that Grew's political economy is best described as mercantilist, this article argues for a much more multifaceted and idiosyncratic reading of Grew's political economy, which aligned with or prefigured not only mercantilism, but also aspects of cameralism, physiocracy, Colbertism, and some of the utopian ideologies of Samuel Hartlib and his circle. By focusing on his knowledge of plant anatomy and plant chymistry, this paper shows that Grew developed a sophisticated understanding of local English ecologies and the natural resource management necessary to maintain a financially strong state. It also reveals an economic thinker deeply skeptical of empire, who was, instead, in favor of national economic self-sufficiency through domestic mineral extraction, agrarian improvement, and a highly regulated market. This article focuses on Grew's development of saline chymistry, his geometric approach to both plant anatomy and geography, his investigations of mineral soils, and his research into tree growth and timber management to demonstrate the deep connections between his botany and his economics.
