Oh, happy he who still hopes he can emerge from Error's boundless sea! - Faust.

The day is committed to error and floundering; success and achievement are matters of long range.

The day is for mistake and error, sequence of time for success and carrying out. The one who anticipates is master of the day.

One errs as long as one strives.

I could never have known so well how paltry men are, and how little they care for really high aims, if I had not tested them by my scientific researches. Thus I saw that most men only care for science so far as they get a living by it, and that they worship even error when it affords them a subsistence.

Should I not be proud, when for twenty years I have had to admit to myself that the great Newton and all the mathematicians and noble calculators along with him were involved in a decisive error with respect to the doctrine of color, and that I among millions was the only one who knew what was right in this great subject of nature?

A stated truth loses its grace, but a repeated error appears insipid and ridiculous.

Error is to truth as sleep is to waking. I have observed that one turns, as if refreshed, from error back to truth.

Nothing is more damaging to the truth than an old error.
