Let me show you the difference between the theological and the secular spirit. Nearly three hundred years ago, one of the noblest of the human race, Giordano Bruno, was burned at Rome by the Catholic Church — that is to say, by the “Triumphant Beast.” This man had committed certain crimes –he had publicly stated that there were other worlds than this — other constellations than ours. He had ventured the supposition that other planets might be peopled. More than this, and worse than this, he had asserted the heliocentric theory — that the earth made its annual journey about the sun. He had also given it as his opinion that matter is eternal. For these crimes he was found unworthy to live, and about his body were piled the fagots of the Catholic Church. This man, this genius, this pioneer of the science of the nineteenth century, perished as serenely as the sun sets. The Infidels of to-day find excuses for his murderers. They take into consideration the ignorance and brutality of the times. They remember that the world was governed by a God who was then the source of all authority. This is the charity of Infidelity, — of philosophy. But the church of to-day is so heartless, is still so cold and cruel, that it can find no excuse for the murdered.
