“How I suffered when I had to preach to you those pious lies that I detest in my heart. What remorse your credulity caused me! A thousand times I was on the point of breaking out publicly and opening your eyes, but a fear stronger than myself held me back, and forced me to keep silence until my death.”

“In short, if youth is not quite right in its opinions, there is a strong probability that age is not much more so. Undying hope is co-ruler of the human bosom with infallible credulity. A man finds he has been wrong at every preceding stage of his career, only to deduce the astonishing conclusion that he is at last entirely right.”

“Mathematical Knowledge adds a manly Vigour to the Mind, frees it from Prejudice, Credulity, and Superstition.”

“Are you really surprised by the endurance of religion? What ideology is likely to be more durable than one that conforms, at every turn, to our powers of wishful thinking? Hope is easy; knowledge is hard. Science is the one domain in which we human beings make a truly heroic effort to counter our innate biases and wishful thinking. Science is the one endeavor in which we have developed a refined methodology for separating what a person hopes is true from what he has good reason to believe. The methodology isn’t perfect, and the history of science is riddled with abject failures of scientific objectivity. But that is just the point-these have been failures of science, discovered and corrected by-what, religion? No, by good science.”

“So this is where all the vapid talk about the ‘soul’ of the universe is actually headed. Once the hard-won principles of reason and science have been discredited, the world will not pass into the hands of credulous herbivores who keep crystals by their sides and swoon over the poems of Khalil Gibran. The ‘vacuum’ will be invaded instead by determined fundamentalists of every stripe who already know the truth by means of revelation and who actually seek real and serious power in the here and now. One thinks of the painstaking, cloud-dispelling labor of British scientists from Isaac Newton to Joseph Priestley to Charles Darwin to Ernest Rutherford to Alan Turing and Francis Crick, much of it built upon the shoulders of Galileo and Copernicus, only to see it casually slandered by a moral and intellectual weakling from the usurping House of Hanover. An awful embarrassment awaits the British if they do not declare for a republic based on verifiable laws and principles, both political and scientific.”

“Tell people there’s an invisible man in the sky who created the universe, and the vast majority will believe you. Tell them the paint is wet, and they have to touch it to be sure.”
