It needs but a glance at Bacon's indefinite outline of a First and Summary Philosophy,[57] to see that it must always be greeted by two opposite sentences of condemnation. A large section of its censors will pronounce the meagreness of its contents "a gentle riddance," or perhaps describe the contents themselves still more harshly as "rubbish shot here." Another section may compare all that it leaves for Metaphysics to the year without its spring, or Shakespeare's masterpiece of philosophy with the part of Hamlet left out. Let us see then how the reserved province was parcelled out.--Bacon himself remarks:--"It may fairly therefore now be asked, what is left remaining for Metaphysic? Certainly nothing beyond nature; but of nature itself much the most excellent part." Most excellent because "Physic handles that which is most inherent in matter and therefore transitory, and Metaphysic that which is more abstracted and fixed. And again, that Physic supposes in nature only a being and moving and natural necessity: whereas Metaphysic supposes also a mind and idea."[58] This search into the Mind of Nature is divided into the investigation of _two_ kinds of causes, still called the Formal and the Final. Bacon's doctrine of Forms--the Philosophy in which is embraced "Natura naturans"--nature engendering nature--the Queen of Art--and the Regent of Production, constitutes one of the most difficult parts of the Novum Organum, the Advancement, and the De Augmentis; and may have been one chief provocative to King James' irreverent similitude. It might, according to some writers, even now prove a veritable "peace of God" could we only grasp its full meaning. "From the discovery of Forms," says Bacon, "results truth in speculation and freedom in operation."[59] And his latest commentator believes that this field of discovery has not been truly explored, because its very idea has been only imperfectly apprehended. The whole question, however, belongs to a future Chapter of this Essay, where we propose examining the Law of Production in its most refined and abstract shape. Yet one further remark may be allowed here. According to Francis Bacon, one "respect which ennobles this part of Metaphysic, is that it enfranchises the power of men to the greatest liberty, and leads it to the widest and most extensive field of operation.... For physical causes give light and direction to new inventions in similar matter. But whosoever knows any Form, knows also the utmost possibility of superinducing that nature upon every variety of matter, and so is less restrained and tied in operation, either to the basis of the matter or to the condition of the efficient."[60]
