Scientists generally, not just evolutionary biologists, don't take much for granted.

Humans have certain properties and characteristics which are intrinsic to them, just as every other organism does. That's human nature.

There are historical analogs, which are not exact, of course, but are close enough to be worrisome. This is a whiff of early Nazi Germany. [Adolf] Hitler was appealing to groups with similar grievances, and giving them crazy answers, but at least they were answers; these groups weren't getting them anywhere else. It was the Jews and the Bolsheviks [that were the problem].

Human physical structures and intellectual structures are generally studied in different ways. The assumption is that physical structures are genetically inherited and intellectual structures are learned. I think that this assumption is wrong. None of these structures is learned. They all grow; they grow in comparable ways; their ultimate forms are heavily dependent on genetic predispositions.

As for academics, I do not see why their responsibilities as moral agents should differ in principle from the responsibilities of others; in particular, others who also enjoy a degree of privilege and power, and therefore have the responsibilities that are conferred by those advantages.

Every great power, every aggressive power has always regarded itself as exceptional and as doing things only for the most moral ends.

There is always room for Gramsci's "optimism of the will."
