I know what Dawkins says about the "blind, pitiless indifference" of nature, the obvious beliefs of naturalists that human emotions are not scientific.
That's confused.
The expression "blind, pitiless indifference" (as applied to nature) is a metaphor. Likewise "selfish gene" is a metaphor. Those terms have no implications for human emotions.
There are scientists, such as research psychologists, who scientifically study human emotions.
