I . Article excerpt. Another important text by Leibniz from the same thread is A Specimen of Discoveries of the Admirable Secrets of Nature in General (Leibniz, 1686). The Thomistic analysis of the concept of transcendental unity is not distinctive in scholastic tradition; however, like Aquinas, Leibniz holds that the principle of individual unity is substantial form, and this doctrine was original with Aquinas. The substantial form plays, therefore, an essential role, not merely in certain kinds of scientific explanation, but by being a fundamental efficient cause in its own right. The concept of substantial forms dominates ancient Greek philosophy and medieval philosophy, but has fallen out of favour in modern philosophy. For Leibniz, the unity of a substance is the undividedness of its being. It is not surprising, in light of Leibniz's reconciliatory nature, that monads bear hallmarks of both Aristotelian and mechanistic philosophy. This anthology is about the signal change in Leibniz’s metaphysics with his explicit adoption of substantial forms in 1678-79. ACCORDING TO LEIBNIZ, (1) there are constraints on what counts as a genuine individual substance. In terms of the former, they do the work of substantial forms, possessing an entelechy which guarantees that they unfold through time as they ought.

Substantial Simplicity in Leibniz: Form, Predication, & Truthmakers . A theory of substantial forms asserts that forms (or ideas) organize matter and make it intelligible.Substantial forms are the source of properties, order, unity, identity, and information about objects. Leibniz’s own version represents a form of concurrentism, since he rejects the view that the change in perceptual states of a created substance is due solely to that created substance itself. A theory of substantial forms asserts that forms (or ideas) organize matter and make it intelligible.Substantial forms are the source of properties, order, unity, identity, and information about objects. When early critics, such as Leibniz, pointed out that there remained some things such as the living force (vis viva ) or the gravitational force at a distance, about which Newton refused to form hypotheses, that still required a substantial form for their explanation, they missed the force of the Galilean arguments as well.
