If a man lose his balance, and immerse himself in any trades or pleasures for their own sake, he may be a good wheel or pin, but he is not a cultivated man.
A mathematician of the first rank, Laplace quickly revealed himself as only a mediocre administrator; from his first work we saw that we had been deceived. Laplace saw no question from its true point of view; he sought subtleties everywhere; had only doubtful ideas, and finally carried the spirit of the infinitely small into administration.
We need to steer clear of this poverty of ambition, where people want to drive fancy cars and wear nice clothes and live in nice apartments but don't want to work hard to accomplish these things. Everyone should try to realize their full potential.
Every man is proud of what he does well; and no man is proud of what he does not do well. With the former, his heart is in his work; and he will do twice as much of it with less fatigue. The latter performs a little imperfectly, looks at it in disgust, turns from it, and imagines himself exceedingly tired. The little he has done, comes to nothing, for want of finishing.
Let not him who is houseless pull down the house of another, but let him work diligently and build one for himself, thus by example assuring that his own shall be safe from violence when built.
And, inasmuch [as] most good things are produced by labour, it follows that all such things of right belong to those whose labour has produced them. But it has so happened in all ages of the world, that some have laboured, and others have, without labour, enjoyed a large proportion of the fruits. This is wrong, and should not continue. To [secure] to each labourer the whole product of his labour, or as nearly as possible, is a most worthy object of any good government.
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!
