Sincerity is no test of truth – no evidence of correctness of conduct. You may take poison sincerely believing it the needed medicine, but will it save your life?
Honesty is the best policy.
A man should never be ashamed to own he has been in the wrong, which is but saying, in other words, that he is wiser to-day than he was yesterday.
A man that should call everything by its right name, would hardly pass the streets without being knocked down as a common enemy.
Candor and generosity, unless tempered by due moderation, lead to ruin.
Take note, take note, O world, To be direct and honest is not safe.
If you are sincere, you have success in your heart, And whatever you do succeeds.
There is no greater delight than to be conscious of sincerity on self-examination.
An honest man’s the noblest work of God.
Sincerity and truth are the basis of every virtue.
