A man who is convinced of the truth of his religion is indeed never tolerant. At the least, he is to feel pity for the adherent of another religion but usually it does not stop there. The faithful adherent of a religion will try first of all to convince those that believe in another religion and usually he goes on to hatred if he is not successful. However, hatred then leads to persecution when the might of the majority is behind it.
More quotes by Albert Einstein
A happy man is too satisfied with the present to dwell too much on the future.
Try to become not a man of success, but try rather to become a man of value.
Life is like riding a bicycle. To keep your balance you must keep moving.
