In America, we hurry-which is well; but when the day's work is done, we go on thinking of losses and gains, we plan for the morrow, we even carry our business cares to bed with us...we burn up our energies with these excitements, and either die early or drop into a lean and mean old age at a time of life which they call a man's prime in Europe...What a robust people, what a nation of thinkers we might be, if we would only lay ourselves on the shelf occasionally and renew our edges!
Mark TwainMan is the only slave. And he is the only animal who enslaves. He has always been a slave in one form or another, and has always held other slaves in bondage under him in one way or another. In our day, he is always some man's slave for wages, and does that man's work; and this slave has other slaves under him for minor wages, and they do his work. The higher animals are the only ones who exclusively do their own work and provide their own living.
