Great stuff here!
It is very interesting to see a bunch of world-famous naturalists grappling with the problem of meaning and naturalism. They lack rationalism to explain naturalism and they are similar to non-naturalist, because they don’t want to give up Meaning by arguments from meaning (except Alex Rosenberg/Dennet?)
I thought a book on Rationalism/Naturalism/Nihilsm is not needed anymore…maybe it is…
