But it is quite obvious that they are not true to an indefinite extent, and that the principles of saving, pushed to excess, would destroy the motive to production.

I have always been an extreme temperance man on principle; but it is useless to push principle to excess, and on this occasion I believe that I finished three-quarters of the bottle.

原则上我一直是一个极度节制的人； 但是过分强调原则是没有用的， 这次我相信我喝完了四分之三的瓶子。
