Finding an answer to this most important question is a quest worth taking.
Who am I? That is one of those questions that is deceptively simple, yet has no easy answer. I am complex.
Paul Creedon, the Practical Humanist, wrote a great post about this, talking about the process of creating identity – see it here http://thepracticalhumanist.blogspot.com/2012/12/identity.html It is a lovely peice.
I like that he makes the answer to this question more about the journey to finding an answer, than it is about the answer itself. He is more concerned with how he approaches the journey than he is with the fact that who he is is constantly changing. I think that is an excellent way to approach this basic existential question.
For me, my practice of humanism starts with the question, not who am I? But rather, who do I really want to be? Now, in this current situation and in the future. Who I am matters, but who I want to be matters more.
This is why it is a journey. A journey that never ends – or a never ending story – love it. And this is why I like my identity as a Humanist so much. It’s not that I have a set dogmatic idea of who I am. It is that I remind myself that I want to be the best human I can be requires me to constantly challenge myself to do and be better. And I find that process immensely satisfying even if it is never complete.
