[Ham, reconstructed]
a) everything is a natural phenomenon
b) morality is something
c) :. morality is a natural phenomenon

I think you have Byrne's argument backward.  I think he is saying:
1) morality is a natural phenomenon
2) astronomy is a natural phenomenon
...
n) :. everything [ = all facts] is a natural phenomenon
