During the last few generations man has been curiously changing.

Much of his old spontaneity of action has gone from him.

He has become a creature looking before and after; and his native hue of resolution has been sickled over by thought.

We admit nothing now without question; we have learnt to take to pieces all motives to actions.

We not only know more than we have done before, but we are perpetually chewing the cud of our knowledge.
