"Now, what I want is Facts. Teach these boys and girls nothing but Facts. Facts alone are wanted in life. Plant nothing else, and root out everything else. You can only form the minds of reasoning animals upon Facts: nothing else will ever be of service to them... Stick to the Facts, sir!"
--Mr. Thomas Gradgrind, quoted in the first paragraph of Charles Dickens' Hard Times
