It is frivolous to fix pedantically the date of particular inventions. They have all been invented over and over fifty times. Man is the arch machine, of which all these shifts drawn from himself are toy models. He helps himself on each emergency by copying or duplicating his own structure, just so far as then need is.
Ralph Waldo EmersonThe spirit of our American radicalism is destructive and aimless; it is not loving; it has no ulterior and divine ends; but is destructive only out of hatred and selfishness.
Ralph Waldo Emerson
