Pinker thinks “science” leads to humanism:
This humanism, which is inextricable from a scientific understanding of the world, is becoming the de facto morality of modern democracies, international organizations, and liberalizing religions, and its unfulfilled promises define the moral imperatives we face today.
Quite the contrary, the so-called humanism of the Pinkers, Richard Dawkins, and the Peter Singers of the world tend decidedly toward utilitarianism, which in turn, leads to anti humanism because it established moral value based on capacities, not on equal value for all humanity. Add in Singer’s animals deserve “equal consideration” utilitarianism, and you have a prescription for the instrumental use of living human beings.
And the latest craze is plants are people too.
Like many fellow scientism adherents, Pinker goes back and forth between science and morality. For example:
Moreover, science has contributed—directly and enormously—to the fulfillment of these values. If one were to list the proudest accomplishments of our species (setting aside the removal of obstacles we set in our own path, such as the abolition of slavery and the defeat of fascism), many would be gifts bestowed by science.
Based on science, what is wrong with slavery? It’s just the powerful prevailing over and forcing their way on the less powerful–a common feature of the natural world. More.
