We can only learn and advance with contradictions.
The faithful inside should meet the doubtful. The doubtful should meet the faithful. Human slowly advances and becomes mature when he accepts his contradictions.

"I think there's a difference between (a) offending people for its own sake, which I don't necessarily want to do, because some people are good and decent and it would be unkind to upset them simply to indulge my own self-importance, and (b) challenging their prejudices, their preconceptions, or their comfortable assumptions. I'm very happy to do that. But we need to be on our guard when people say they're offended. No one actually has the right to go through life without being offended. Some people think they can say "such-and-such offends me" and that will stop the "offensive" words or behaviour and force the "offender" to apologise. I'm very much against that tactic. No one should be able to shut down discussion by making their feelings more important than the search for truth. If such people are offended, they should put up with it."

For when we allow the arguments of reason to oppose one another with perfect freedom, something useful and serviceable for the correction of our judgements will always result, though it may not always be what we were looking for.

Although we cannot rid ourselves of misconceptions, we can correct them when we become aware of them.

there is no circumstance, in all the contradictions of our most mysterious nature, that appears to be more humiliating than the use we are disposed to make of those sad examples which seem purposely marked for our correction and improvement.

Being open to correction means making ourselves vulnerable, and many people are not willing to do that.

When we wish to correct with advantage, and to show another that he errs, we must notice from what side he views the matter, for on that side it is usually true, and admit that truth to him, but reveal to him the side on which it is false. He is satisfied with that, for he sees that he was not mistaken, and that he only failed to see all sides. Now, no one is offended at not seeing everything; but one does not like to be mistaken, and that perhaps arises from the fact that man naturally cannot see everything, and that naturally he cannot err in the side he looks at, since the perceptions of our senses are always true.

if to please the people,we offer what we ourselves disapprove, how can we afterwards defend our work? Let us raise a standard to which the wise and honest can repair. The rest is in the hands of God.

For disappointments, that come not by our own folly, they are the trials or corrections of Heaven: and it is our own fault, if they prove not our advantage.

We need very strong ears to hear ourselves judged frankly, and because there are few who can endure frank criticism without being stung by it, those who venture to criticize us perform a remarkable act of friendship, for to undertake to wound or offend a man for his own good is to have a healthy love for him.

Meaning lies in the confrontation of contradiction - the coincidencia apositorum. That’s what we really feel, not these rational schemes that are constantly beating us over the head with the “thou shalts” and “thou should”, but rather a recovery of the real ambiguity of being and an ability to see ourselves as at once powerful and weak, noble and ignoble, future-oriented, past-facing.

A coach is someone who can give correction without causing resentment.

The force of the temptation which urges us to seek for such evidence and appearances as are in favour of our desires, and to disregard those which oppose them, is wonderfully great. In this respect we are all, more or less, active promoters of error. In place of practising wholesome self-abnegation, we ever make the wish the father to the thought: we receive as friendly that which agrees with, we resist with dislike that which opposes us; whereas the very reverse is required by every dictate of common sense.

I like contradictions. We have never attained the infinite variety and contradictions that exist in nature. Tomorrow I shall contradict myself. That is the one way I have of asserting my liberty, the real liberty one does not find as a member of society.
