The effort is as evident and quite as laborious in modern science, starting as it does from multiplicity, as in Thomas Aquinas who started from unity, and it is necessarily less successful, for its true aims as far as it is Science and not disguised Religion, were equally attained by reaching infinite complexity; but the assertion or assumption of ultimate unity has characterised the Law of Energy as emphatically as it has characterised the definition of God in Theology. If it is a reproach to Saint Thomas, it is equally a reproach to Clerk-Maxwell. In truth it is what most men admire in both — the power of broad and lofty generalisation.
