A commemorative speech delivered at the centenary of Voltaire's death examines the paradox of human progress as both an evolution and a revolt against the past. The orator portrays Voltaire as the conscience of an age who challenged despotism, priestcraft, and inherited authority, highlighting his role in advancing reason, tolerance, and secular liberty. The address balances admiration with recognition of the hostility reformers face, warns that social advance requires replacing superstition and tyranny with knowledge and compassion, and reflects on memory, civic responsibility, and the moral duties that sustain a free society.
