The power of a government by discussion as an instrument of elevation plainly depends--other things being equal--on the greatness or littleness of the things to be discussed. There are periods when great ideas are 'in the air,' and when, from some cause or other, even common persons seem to partake of an unusual elevation. The age of Elizabeth in England was conspicuously such a time. The new idea of the Reformation in religion, and the enlargement of the MOENIA MUNDI by the discovery of new and singular lands, taken together, gave an impulse to thought which few, if any, ages can equal. The discussion, though not wholly free, was yet far freer than in the average of ages and countries. Accordingly, every pursuit seemed to start forward. Poetry, science, and architecture, different as they are, and removed as they all are at first sight from such an influence as discussion, were suddenly started onward. Macaulay would have said you might rightly read the power of discussion 'in the poetry of Shakespeare, in the prose of Bacon, in the oriels of Longleat, and the stately pinnacles of Burleigh.' This is, in truth, but another case of the principle of which I have had occasion to say so much as to the character of ages and countries. If any particular power is much prized in an age, those possessed of that power will be imitated; those deficient in that power will be despised. In consequence an unusual quantity of that power will be developed, and be conspicuous. Within certain limits vigorous and elevated thought was respected in Elizabeth's time, and, therefore, vigorous and elevated thinkers were many; and the effect went far beyond the cause. It penetrated into physical science, for which very few men cared; and it began a reform in philosophy to which almost all were then opposed. In a word, the temper of the age encouraged originality, and in consequence original men started into prominence, went hither and thither where they liked, arrived at goals which the age never expected, and so made it ever memorable. In this manner all the great movements of thought in ancient and modern times have been nearly connected in time with government by discussion. Athens, Rome, the Italian republics of the Middle Ages, the COMMUNES and states-general of feudal Europe, have all had a special and peculiar quickening influence, which they owed to their freedom, and which states without that freedom have never communicated. And it has been at the time of great epochs of thought--at the Peloponnesian war, at the fall of the Roman Republic, at the Reformation, at the French Revolution--that such liberty of speaking and thinking have produced their full effect.
