Cases like this are the triumph of theories. They show at once how large a part pure reason has to perform in our examination of nature, and how implicit our reliance ought to be on that powerful and methodical system of rules and processes which constitute the modern mathematical analysis, in all the more difficult applications of exact calculation to her phenomena. ) To take an instance more within ordinary apprehension. An eminent living geometer had proved by calculations, founded on strict optical principles, that in the centre of the shadoiu of a small circular plate of metal, exposed in a dark room to a beam of light emanating from a very small brilliant pointy D 34 DISCOURSE ON THE STUDY there ought to be no darkness, — in fact, no shadow at that place ; but, on the contrary, a degree of illumination precisely as bright as if the metal plate were away.

To obey a law, to act in compliance with a rule, supposes an understanding and a will, a power of complying or not, in the being who obeys and complies, which we do not admit as belonging to mere matter.

Now, in this research there would seem one great question to be disposed of before our enquiries can even be commenced with any thing like a prospect of success, which is, whether the laws of nature themselves have that degree of permanence and fixity which can render them subjects of systematic discussion ; or whether, on the other hand, the qualities of natural agents are subject to mutation from the lapse of time. To the ancients, who lived in the infancy of the world, or rather, in the infancy of man's experience', this was a very rational subject of question, and hence their distinctions between corruptible and incorruptible matter.
