• A well-instructed people alone can be permanently a free people.
• To the press alone, chequered as it is with abuses, the world is indebted for all the triumphs which have been gained by reason and humanity over error and oppression.

• Let me recommend the best medicine in the world: a long journey, at a mild season, through a pleasant country, in easy stages.
• Learned Institutions ought to be favorite objects with every free people. They throw that light over the public mind which is the best security against crafty and dangerous encroachments on the public liberty.
