Half of the harm that is done in this world is due to people who want to feel important. They don’t mean to do harm – but the harm does not interest them.
A harmful truth is better than a useful lie.
The people who do us most harm are the people who shield us from reality.
People never dream what harm they may do by ‘educating’ someone! Often it’s cruelty, not kindness!
Men do as much harm as they dare, and as much good as they must.
Inestimable harm may be done by foolish wagging of tongues in ill-natured gossip.
Almost no one is perceptive enough to realize all the harm he does.[Il n’y a guère d’homme assez habile pour connaître tout le mal qu’il fait.]
