I think this is the biggest thing that will be relevant to the next generation. They seem far less concerned about origins and metaphysics than justice, ethics, and meaning.
This is probably true as a description of the younger generation. Yet previous generations were able to locate their concerns about justice, ethics, and meaning within accounts of origins and metaphysics; if those two lines of concern are separated, then in the long run the accounts of justice, ethics, and meaning will suffer.
I do understand why many young people are not attracted to traditional dogmatism, and why they might want to avoid some questions which they associate with unhealthy dogmatic answers. But in the long run, even if the old dogmas need replacement, there is no avoiding metaphysical questions, even if one’s primary concern is social justice. The noble civil rights movement only makes sense within a doctrine of the equality of all men which the West got from the Bible, and is definitely a metaphysical doctrine. If we had to prove empirically that all men were equal, it wouldn’t be easy, and the old doctrine that some men were natural slaves could easily crop up again. The metaphysical postulate of equality is what gave the civil rights movement its moral bite. So the trick is how to show young people that the great metaphysical questions are still relevant to daily life, even if some of the old answers to those questions can no longer be accepted.
