We have hitherto considered only two possibilities: that the received opinion may be false, and some other opinion, consequently, true; or that, the received opinion being true, a conflict with the opposite error is essential to a clear apprehension and deep feeling of its truth. But there is a commoner case than either of these; when the conflicting doctrines, instead of being one true and the other false, share the truth between them.

So long as an opinion is strongly rooted in the feelings, it gains rather than loses in stability by having a preponderating weight of argument against it.

The English, of all ranks and classes, are at bottom, in all their feelings, aristocrats. They have some concept of liberty, and set some value on it, but the very idea of equality is strange and offensive to them. They do not dislike to have many people above them as long as they have some below them.

What a country wants to make it richer is never consumption, but production. Where there is the latter, we may be sure that there is no want of the former. To produce, implies that the producer de_sires to consume; why else should he give himself useless labor? He may not wish to consume what he himself produces, but his motive for producing and selling is the desire to buy. Therefore, if the producers generally produce and sell more and more, they certainly also buy more and more.

It is given to no human being to stereotype a set of truths, and walk safely by their guidance with his mind's eye closed.

The ends of scientific classification are best answered, when the objects are formed into groups respecting which a greater number of general propositions can be made, and those propositions more important, than could be made respecting any other groups into which the same things could be distributed. ... A classification thus formed is properly scientific or philosophical, and is commonly called a Natural, in contradistinction to a Technical or Artificial, classification or arrangement.

The love of power and the love of liberty are in eternal antagonism.
