To make a book is as much a trade as to make a clock; something more than intelligence is required to become an author.

There is as much trickery required to grow rich by a stupid book as there is folly in buying it.

When, after having read a work, loftier thoughts arise in your mind and noble and heartfelt feelings animate you, do not look for any other rule to judge it by; it is fine and written in a masterly manner.

When a book raises your spirit, and inspires you with noble and manly thoughts, seek for no other test of its excellence. It is good, and made by a good workman.
