You know the feeling when you suddenly realize that something inside you have changed. Something with your personality, level of knowledge, values etc. had changed without you noticing it. A typical situation for me would be a discussion around politic. Suddenly you agree with someone who you totally disagreed with before. Like jumping from right to left on the political scale. This change could because of new knowledge you got from talking to new people, taking education or just the fact being abroad away from everything.
Well at these situations I sometimes feel some pride in not letting go of old knowledge. Just like politicians when had made a statement years ago and now being put accountable for in the press. Sometimes it's because that same politicians suddenly changed that statement or promise. The press will not let it go that he or her changed his view and will make him look like a person you cannot trust. He or her therefore has to defend his view and argue for that both view are valid somehow- strange moments. But I can see myself in those situations.
You know you might be wrong but because of past incidents you will not change because you lose some pride. Like living by the statement " one time right, always right".
It could also be personally. Having a discussion around a topic where you definitely had the edge in level of knowledge against another person. Then month later you are having a similar discussion again but know the other person has the edge against you. Instead of letting go and actually just learn, you defend your points just to get the "old" edge back even though you know it's not true.
Knowledge should help you or be beneficial for you but sometimes it just helps to create a moment where you feel you lose something by using the knowledge.
