  • We should not object to that inequality which is natural -- to the superior ability and superior virtue which place one man far above his fellows; but we should object to an immense inequality, _which is not natural_, and which sometimes places the superior man at the mercy and in the service of one who has no ability whatever, -- who is simply born to rule by means of _hereditary wealth_.

    The Arena Volume 4, No. 20, July, 1891

  • The prophecies of the Bible are not vague general denunciations of natural decline and extinction to all the nations of the world, which, if they were merely the exposition of a universal _natural_ law of national death, they would be; nor yet the application of any such natural and inevitable law to some particular nation, denouncing its destruction, without any specification of time, manner, instrument, or cause of its infliction.
