A sentimental view of human life is one in which one adopts a certain belief because it makes one feel good (or bad, for that matter), or one slurs over what human life is really like with vague, pleasant-sounding comments, or one ignores what human life is really like completely. By "human life," I mean human life as a whole, not the life of this or that person.
Robin,
"makes one feel good" is a purpose! To slur over "what human life is really like ... ignores what human life is really like"
"really like" you are here I think asking for a ideal platonic meaning, or form for a human life.
"human life as a whole" is an abstraction! An abstraction! At this point I think you may as well let the question expand all the way, I don't see any meaningful limit, to the question of "The meaning of life, the universe, and everything".
And God's latest revelation to St. Dougles Adams is that there is an answer to that, rest assured, it is 42! IIRC, I've misplaced the scripture.
But seriously, I think we have to back this up and ask if you are asking meaningful questions. I think you have gone astray with your semantics and gotten off into a confused philosophy as a result.
