"How do you find out something is true? If you have these theories of the different religions then you begin to wonder. Once you start doubting, which to me is a fundamental part of my soul, it is then a little harder to believe. I can live with doubt and uncertainty and not knowing, I think it is much more interesting to live not knowing than to have answers which might be wrong. I have approximate answers and possible believes and different degrees of uncertainty about different things but I am not absolutely sure of anything and in many things I don't know anything about.

But I don't have to know an answer, I don't feel frightened by not knowing things, by being lost in the misterious universe without any purpose, it doesn't frightened me."
