The use of a theory in the real sciences is to help the investigator to a complete view of all the hitherto discovered facts relating to the science in question; it is a collected view, Btwpia, of all he yet knows in one. Of course, whilst any pertinent facts remain unknown, no theory can be exactly true, because every new fact must necessarily, to a greater or less degree, displace the relation of all the others. A theory, therefore, only helps investigation; it cannot invent or discover. The only true theories are those of geometry, because in geometry all the premisses are true and unalterable.

Mr. Lyell's system of geology is just half the truth, and no more. He affirms a great deal that is true; and he denies a great deal which is equally true; which is the general characteristic of all systems not embracing the whole truth.
