ABSTRACT Within the context of national traditions in colonial science, the scientific activities of Jesuit missionaries present us with a unique combination of challenges. The multinational membership of the Society of Jesus gave its missionaries access to virtually every Portuguese, Spanish, and French colony. The Society was thus compelled to engage an astonishingly diverse array of cultural and natural environments, and that diversity of contexts is reflected in the range and the complexity of Jesuit scientific practices. Underlying that complexity, however, (...) was what I see as a unique combination of institutional structures; namely, European colleges, overseas mission stations, and the regular circulation of personnel and information. With this institutional framework as a backdrop, I briefly trace what I see as the most salient themes emerging from recent studies of Jesuit overseas science: 1) the Societys ability to use scientific expertise to its advantage amid the complex web of dependencies upon which it missionary activities rested; 2) the ability of its missionaries to become intimate with a wide range of cultures and to appropriate natural knowledge held by indigenous peoples, especially in the fields of material medica and geography; and 3) the different ways Jesuits used published accounts of “remote nature” (i.e., natural histories of overseas colonies) to advance their corporate and religious causes.
