If the purpose of life is to "build as many feeling entities..." then that is what should be done. You see, it is the way that we arrive at our understanding of the purpose that convinces us that it is right. By using the scientific method we can feel confident that we have discovered truth. Science provides us with evidence for why we should believe things and when we have evidence we have two options: we can either be rational and change our beliefs based on evidence, or be irrational and ignore the evidence. The type of "purpose of life" that I'm talking about would only be discoverable by intense scientific activity. It would be like the laws of physics: so undeniably true that you'd be a fool to not believe them. That said, I think your postulated "build as many feeling..." purpose of life is particularly unlikely. However, because no one has ever seen the purpose of life before, we must be careful to not rule out things prematurely, no matter how absurd they seem. I imagine most people of Darwin's time were so set on the idea of creationism that evolution was inconceivable, thankfully Darwin saw through that.
