Their first point is that saying the values are already there. The most obvious value of science is truth, which can be reached by the scientific method, which allows paradigms to change. Giving so much importance to truth is a matter of faith, you don't derive that from somewhere. It's interesting that they're going further than that and apparently find awe and meaning even just from the scientific method. Awe and meaning are in short supply in this world, so it's worth asking if we can get more of it from science, instead of pretending it's not there.
