Great wars disturb the masses. They awaken them from the plodding, dull routine of physical labor, and, thrusting great questions of conquest and defense, of justice and honor, before them, agitate them into thought. Conditions change; new ideas take the place of old ones, and a revolution in thought and action follows. But a war of ideas, starting from principles of peace, brings the enslaved again to the sword, and this crisis is termed a revolution. Junius wrote at the dawn of the age of revolutions. The war of ideas was waged against priestcraft, and skepticism was the result. Voltaire had struck fable from history with the pen of criticism, and a scientific method here dawned upon history. Rousseau's democracy had entered the hearts of the down-trodden in France, and, a wandering exile, he had spread the contagion in England. George Berkeley, the Irish idealist, had just died, and the Scotch Thomas Reid arose with the weapon of common sense to test the metaphysician's ideas. Common Sense was, in the strictest sense, revolutionary, and, under the tyranny of king, lords, and commons, meant war. It was not a phrase without meaning, but a principle proclaimed, and it passed more readily into the understanding of the common people because conveyed in common speech. When Reid said, "I despise philosophy, and renounce its guidance; let my soul dwell in common sense," he illuminated all Britain and America. The philosophy of common sense entered the professor's chair, invaded the pulpit, and, having passed thence into the humblest cottage, soon took a higher range--it went immediately up and knocked at the king's gate. It would be false to say it found admittance there. It was only because there had been a new world opened as an asylum for the oppressed of every land, that it did not sweep kings and monarchs from all the high places in Europe. At this time, too, Mr. Pitt, the great commoner, the friend of common sense and English liberty, in his old age, war-worn and sick, had compromised with his vanity for a title. In his great fall from Pitt to Chatham, from the people to a peerage, he gained nothing but lost his good name. He exchanged worth for a bauble, and a noble respect for the contempt of nobles and the sorrows of the people. Mr. Pitt had departed, Lord Chatham was passing away; and in any assault by a trafficking ministry and corrupt legislature upon the people's rights, there was no one left to bend the bow at the gates.
