To be inevitable is to be inevitable with no exceptions. Though can you find something inevitable around you? Almost everything is not like what you have wanted it to be? If you have ever done something exactly as you had intended, who can deny that it had happed to be so by chance. All is ruled by contingency. If only one can understand it, he can see the truth. Though, one who is happy now can hardly understand it, because he doesn' t want to admit his happiness to be contingent. Such person is sure to pray t o God when he happen to meet a misfortune, saying to himself "How can this happen to Me!". Then, after the misfortune has gone, he thinks that God helped him and say to himself ,"I have been chosen again.", without knowing that it only happened to be so by chance.
