To be rooted in experience

Although I may not agree with the Existentialist way of thinking, I can say I appreciate the way philosophers in this teaching are going towards the importance of experience.  An existentialist would say that in order to understand human freedom or the purpose of life, one must search for the meanings through life.  What one believes is important in life will be the meaning of  that person's life.  I believe there's something magical in that line of thinking.  If you believe life could and can be one way, you should chase after that.  However, this theory could also favor  those who find evil meanings to be their meanings of  life.
