I am not sure that this question should be posted to you, philosophers. But I think philosophy has been talking about everything in life. Anyway, my question is : Do we have to has a fix principles and values that never be changed? I mean, we almost consider changing is a positive thing, and everything we believe in must be criticized and examined and consequently, changed ... if so, is it reasonable for people to Struggle for their principles If they believe that this principle may be changed anytime? Does the fact of “change” eliminates the value of”principle”? Thank you
