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.
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.
A man that should call everything by its right name, would hardly pass the streets without being knocked down as a common enemy.
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.
An honest man is always a child.
