time, be put off, it could not be otherwise than that Europe should be left in that deplorable state which must result when the intellect of a people has outgrown its formulas of faith. A fearful condition to contemplate, for such a dislocation must also affect political relations, and necessarily implies revolt against existing law. Nations plunged in the abyss of irreligion must necessarily be nations in anarchy. For a time their tendency to explosion may be kept down by the firm application of the hand of power; but this is simply an antagonism, it is no cure. The social putrefaction proceeds, working its way downward into classes that are lower and lower, until at length it involves the institutions that are relied on for its arrest. Armies, the machinery of compression, once infected, the end is at hand, but no human foresight can predict what the event shall be, especially if the contemporaneous ruling powers have either ignorantly or wilfully neglected to prepare society for the inevitable trial it is about to undergo. It is the most solemn of all the duties of governments, when once they have become aware of such a momentous condition, to prepare the nations for its fearful consequences. For this it may, perhaps, be lawful for them to dissemble in a temporary manner, as it is sometimes proper for a physician to dissemble with his patient; it may be lawful for them even to resort to the use of force, but never should such measures of doubtful correctness be adopted without others directed to a preparation of the mass of society for the trials through which it is about to pass. Such, doubtless, were the profound views of the great Italian statesmen of the Middle Ages; such, doubtless, were the arguments by which they justified to themselves resistance against the beginning of the evil--a course for which Europe has too often and unfairly condemned them. [Sidenote: Summary of the preceding theories.] It remains for us now to review the details presented in the foregoing pages for the purpose of determining the successive phases of development through which the Greek mind passed. It is not with the truth or fallacy of these details that we have to do, but with their order of occurrence. They are points enabling us to describe graphically the curve of Grecian intellectual advance. The starting point of Greek philosophy is physical and geocentral. The earth is the grand object of the universe, and, as the necessary result, erroneous ideas are entertained as to the relations and dimensions of the sea and air. This philosophy was hardly a century old before it began to cosmogonize, using the principles it considered itself sure of. Long before it was able to get rid of local ideas, such as upward and downward in space, it undertook to explain the origin of the world.
