random quotes ... to amuse, inspire, enrage:
  I am really mortified to be told that, in the United States of America, a fact like this [prosecution of the sale of a book on the creation of the world] can become a subject of inquiry, and of criminal inquiry too, as an offence against religion; that a question about the sale of a book can be carried before the civil magistrate. Is this then our freedom of religion? and are we to have a censor whose imprimatur shall say what books may be sold, and what we may buy? And who is thus to dogmatize religious opinions for our citizens? Whose foot is to be the measure to which ours are all to be cut or stretched?
