An absence of morality

A Harvard psychologist reaches essentially the same conclusion I have about morality and its universal applicability:

Here is the worry. The scientific outlook has taught us that some parts of our subjective experience are products of our biological makeup and have no objective counterpart in the world. The qualitative difference between red and green, the tastiness of fruit and foulness of carrion, the scariness of heights and prettiness of flowers are design features of our common nervous system, and if our species had evolved in a different ecosystem or if we were missing a few genes, our reactions could go the other way. Now, if the distinction between right and wrong is also a product of brain wiring, why should we believe it is any more real than the distinction between red and green? And if it is just a collective hallucination, how could we argue that evils like genocide and slavery are wrong for everyone, rather than just distasteful to us?

I can only marvel at the way my various atheist critics get tremendously upset when I point out the very same conclusion that secular scientists are reaching. If God does not exist, then no objective and universal morality exists either. This is really not up for debate among anyone who is sufficiently educated and capable of basic logic.

And furthermore, this is precisely why the secular position gravitates so readily and reliably towards totalitarianism, because in the absence of any objective and universal morality, one must be created and imposed.

I note, however, that Pinker is incorrect about Plato somehow disproving the idea that God can define morality. He’s implicitly referring to Euthyphro here, which no one has successfully disputed that I have conclusively refuted.
