For to err in opinion, though it be not the part of wise men, is at least human.

Being wrong is ordinary. It is not admirable and it is not a scandal either, and treating your own mistaken opinions as disgraceful is what makes people defend them long past the point of sense. The wise are not those who avoid error but those who let it go quickly.

When you find you have been wrong about something, say so plainly and without a performance of shame. One sentence is enough. You will notice that people think better of you afterwards, and that the next correction reaches you sooner.
