“If you're too sloppy, then you never get reproducible results, and then you never can draw any conclusions; but if you are just a little sloppy, then when you see something startling, (…) you nail it down (…). So I called it the "Principle of Limited Sloppiness."”

You Never Can Tell (1895).
Poetry quotes
Context: p>You never can tell when you do an act
Just what the result will be;
But with every deed you are sowing a seed,
Though the harvest you may not see.
Each kindly act is an acorn dropped
In God's productive soil;
You may not know, yet the tree shall grow
And shelter the brows that toil.You never can tell what your thoughts will do
In bringing you hate or love;
For thoughts are things, and their airy wings
Are swifter than carrier doves.
They follow the law of the universe —
Each thing must create its kind;
And they speed o'er the track to bring you back
Whatever went out from your mind.</p
