is there such a thing as a purpose?

can a person arrive somewhere with a purpose? yes and no. it's probably a very useful thing to do, to arrive somewhere with one purpose. at the same time, isn't one purpose always part of a larger purpose? or, if not that, isn't a purpose always related to an array of other purposes? isn't this true at least in a practical sense? isn't the idea of a purpose isolated from any other purpose just an abstraction? such an abstraction may have its purpose. we again must make a choice, to investigate the idea of an absolute purpose, or to investigate the cloud of purposes which seems more likely to describe our lives

... which seems more practical. (or ... which seems more practical?)
