Life is precious, so I ought to spend my days, you know, making sandwiches for homeless people and tending to the elderly in hospice care. Life is precious, so I should give everything away, except that I live in the world. And in the world, I actually have needs and wants, and I value my needs and wants. And I live in the world, and I can't just go make sandwiches every day because I also have to take kids to school. I also have to, you know, write books because that's my livelihood.
Everybody's got a worldview, whether they know they have it or they don't. They might even get it when they are little tiny kids. Suppose they get it when they are in college, which is often the case, or in high school, whatever. Everything they learn after that or every thing they see after that, they fit it into that worldview. And they are making coherence of what's good, what's bad, what will work, what won't work, what's noble, what's ignoble, and so on... all through this filter.
