FORE:According to Bacon, the object of science is to analyse the complex of Forms making up an individual aggregate into its separate constituents; the object of art, to superinduce one or more such Forms on a given material. Hence his manner of regarding them differs in one important respect from Aristotle��s. The Greek naturalist was, before all things, a biologist. His interest lay with the distinguishing characteristics of animal species. These are easily discovered by the unassisted eye; but while they are comparatively superficial, they are also comparatively unalterable. The English experimenter, being primarily concerned with inorganic bodies, whose properties he desired to utilise for industrial purposes, was led to consider the attributes of an object as at once penetrating its inmost texture, and yet capable of being separated from it, like heat and colour for instance. But, like every other thinker of the age, if he escapes from the control of Aristotle it is only to fall under the dominion of another Greek master��in this instance, Democritus. Bacon had a great admiration for the Atomists, and although his inveterate Peripatetic proclivities prevented him from embracing their theory as a whole, he went along with it so far as to admit the dependence of the secondary on the primary qualities of matter; and on the strength of this he concluded that the way to alter the properties of an object was to alter the arrangement of its component particles.Examining machines made by the best designers, it will be found that their dimensions bear but little if any reference to calculated strains, especially in machines involving rapid motion. Accidents destroy constants, and a draughtsman or designer who does not combine special and experimental knowledge with what he may learn from general sources, will find his services to [89]be of but little value in actual practice. FORE:It is interesting to observe how, here also, the positive science of the age had a large share in determining its philosophic character. Founded on the discovery of the earth��s true shape, Aristotle��s metaphysics had been overthrown by the discovery of the earth��s motion. And now the claims of Cartesianism to have furnished an exact knowledge of matter and a definition of it whence all the facts of observation could be deduced �� priori, were summarily refuted by the discovery421 of universal gravitation. The Cartesians complained that Newton was bringing back the occult qualities of the Schoolmen; but the tendency of bodies to move towards one another proved as certain as it was inexplicably mysterious. For a time, the study of causes was superseded by the study of laws; and the new method of physical science moved in perfect harmony with the phenomenism of Locke. One most important consequence of this revolution was to place the new Critical philosophy on a footing quite different from that occupied by the ancient sceptics. Both restricted certain knowledge to our own states of consciousness; but it now appeared that this might be done without impeaching the value of accepted scientific conclusions, which was more than the Academic philosophy would have admitted. In other words, granting that we were limited to phenomena, it was shown that science consisted in ascertaining the relations of these phenomena to one another, instead of to a problematic reality lying behind them; while, that such relations existed and were, in fact, part of the phenomena themselves, was what no sceptic could easily deny.The signal went forward.
