@maxdancona,
I agree with Maxdancona on this distinction. Cultures and worldviews are
inventions (I use the synonymn, (social
constructions). Our meaningful life is to a large extent
made up over the centuries as exercises in social cooperation and competition. Most people seem to prefer the idea that our categories and meanings are
discoveries of things that sit "out there" in the objective world awaiting our discovery--this is more consistent with the notion that God or gods construct/create our world rather than us. Humanism is more inclined to give humankind credit for the creation of his intersubjective world (his meaningful or culturally constituted/interpreted world). I am--and I think Fresco is--willing to use the term, "discovery", in reference to the fact that most of my meaningful world (my worldview or culture) has been invented by earlier generations
of humans and then discovered by me (with the help of teachers of various kinds) in my formative years. That is not inconsistent with my (and Maxdancona's) constructionist perspective.
