What is toleration? It is the appurtenance of humanity. We are all full of weakness and errors; let us mutually pardon each other our follies—it is the first law of nature.
Until you have formed the habit of looking for the good instead of the bad there is in others, you will be neither successful nor happy.
Toleration is the greatest gift of the mind; it requires the same effort of the brain that it takes to balance oneself on a bicycle.
Tolerance becomes a crime when applied to evil.
In order to have faith in his own path, he does not need to prove that someone else’s path is wrong.
Discord is the great evil of the human species, and toleration is its only remedy.
Cruelty and intolerance towards those who do not belong to it are natural to every religion.
