Feeling is an art and, like any other art, can be acquired by taking pains. - Samuel Butler

Silence is not always tact and it is tact that is golden, not silence.

We take it that when the state of things shall have arrived which we have been above attempting to describe, man will have become to the machine what the horse and the dog are to man. He will continue to exist, nay even to improve, and will be probably better off in his state of domestication under the beneficent rule of the machines than he is in his present wild state. We treat our horses, dogs, cattle and sheep, on the whole, with great kindness, we give them whatever experience teaches us to be best for them, and there can be no doubt that our use of meat has added to the happiness of the lower animals far more than it has detracted from it; in like manner it is reasonable to suppose that the machines will treat us kindly, for their existence is as dependent upon ours as ours is upon the lower animals.

It is far safer to know too little than too much. People will condemn the one, though they will resent being called upon to exert themselves to follow the other.
