The act of tolerating; the allowance of that which is not wholly approved.
Specifically, the allowance of religious opinions and modes of worship in a state when contrary to, or different from, those of the established church or belief.
Hence, freedom from bigotry and severity in judgment of the opinions or belief of others, especially in respect to religious matters.
I have learned silence from the talkative, toleration from the intolerant, and kindness from the unkind; yet, strange, I am ungrateful to those teachers. Khalil Gibran
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. Helen Keller
