Abstract
John Case , the most important English Aristotelian of the Renaissance period, has not yet received the attention he deserves. In his Lapis philosophicus , an exposition of Aristotle's Physics, is found a discussion of the relation of nature to art which parallels in many ways that formulated a few years later in the writings of Francis Bacon. Case argues, in a way more reminiscent of the works of Giambattista della Porta than of those of Aristotle, that the natural philosopher can legitimately apply the productive arts in helping nature to fulfill her function.
