On Liberty

Chapter 2 - OF THE LIBERTY OF THOUGHT AND DISCUSSION.  Part 3 "To abate the force of these considerations, an enemy of free discussion may be supposed to say, that there is no necessity for mankind in general to know and understand all that can be said against or for their opinions by philosophers and theologians. That it is not needful for common men to be able to expose all the misstatements or fallacies of an ingenious opponent."
