What does time makes more converts than reason?

This quote is simply saying that you can reason with someone on the pros of a belief and not get good results if he or she has nothing to compare it to. People change as time goes on. The person experience what life has to offer rather it is good or bad. He or she is more likely to agree with the belief. They can draw on their experiences to decide the truth of a belief. Some people go through changes day by day. For others, it takes a little more time than usual.
