In order to understand how far Bruno has moved at this, the final stage of his philosophy, from the Neoplatonism of its beginnings, the ninth chapter of the last book of the _De Immenso_ must be taken into account.[327] It is interesting in view of the relation of Spinoza to Bruno, as well as of the consistency of Bruno's own thought. In it the existence of _abstract ideal types_ is contended against,--"Nowhere is essence apart from existence;--nature is nothing but the virtue that is immanent (_insita_) in things, and the law by which all things fulfil their course. There is no abstract that subsists in logical reason but not in reality, no justice by which things are just, no goodness through which they are good, wisdom through which they are wise, nor are _deitas_ and _feritas_ the ground of existence of gods and beasts: nor is it light by which shining bodies shine, nor shadow by which folly, darkness, fictions, nonsense come to exist." The student of nature must not suppose form and matter, light and colour and motion, to exist separately by themselves because they may be conceived or defined by themselves. There is then no archetypal world to which the Creator looked in fabricating this of ours, but nature produces all things from within itself, without thought or hesitation. "Study to know where Nature and God are, for there are the causes of things, the life of principles, the source of elements, the seeds of the things that are to be brought forth, the typal forms, active potency producing all things, ... there is also matter, the underlying passive potency, abiding, present, ever coming together into one as it were, for it is not as if a creator came from on high, to give it order and form from without. Matter pours forth all things from its own lap, Nature itself is the inward workman, a living art, a wondrous virtue which is endowed with mind, giving realisation to a matter which is its own, not foreign to itself; not hesitating, but producing all things easily out of itself, as fire shines and burns, as light spreads without effort through space.... Nature is not so miserably endowed as to be excelled by human art, which is directed by a kind of internal sense, while several kinds of animals, guided by their inward mind, show an innate foresight of a wonderful kind,--ants and the industrious bees, which have no type or model spread before them. For there is a nature which is _more than present to_, which is _immanent in_ things, remote from none as none is remote from being, except the false: and while only the surface of things without changes, deeper in the heart of all than is each to itself it lives, the principle of existence, source of all forms, ... Mind, God, Being, One, Truth, Fate, Reason, Order."[328] _Natura naturata_ is thus not a resultant or outcome of _natura naturans_ with Bruno; they are one and the same thing under different aspects, and both are one with God, the living force in things.
