'Things
don't have purposes, as if the universe were a machine, where every
part has a useful function. What's the function of a galaxy? I don't
know if our life has a purpose and I don't see that it matters. What
does matter is that we're a part. Like a thread in a cloth or a
grass-blade in a field. It is and we are. What we do is like wind
blowing on the grass."
