An unpublished manuscript on eucharistic metaphysics by Thomas White (1593–1676) supplies new information about his contributions to philosophy and theology—especially his irenic efforts to find middle ground between traditional Aristotelian views and challenges from the new mechanical philosophy. The work by White studied here, “A Discourse Concerning the Eucharist,” sheds light on his other writings and is illuminated by them. Substance, quantity, place, and accident were the main philosophical issues at stake in White's attempt to give a reasoned account of (...) controversial religious and theological issues, especially transubstantiation and the real presence.
