We are all members of the same flawed species. Putting our moral vision into practice means imposing our will on others. The human lust for power and esteem, coupled with its vulnerability to self-deception and self-righteousness, makes that an invitation to a calamity, all the worse when the power is directed at a goal as quixotic as eradicating human self-interest.
Interpretation
The quote suggests that our attempts to impose our moral beliefs on others can lead to negative consequences, given our flawed nature and inherent self-interest.
In this quote, Steven Pinker reflects on the complexities of human nature, emphasizing that while we aspire to promote moral ideals, the very act of imposing these ideals upon others can lead to disastrous outcomes. He highlights the contradictions of our species, combining the desire for power and recognition with the tendency towards self-deception. This makes any grand effort to eliminate self-interest a potentially futile and chaotic endeavor.
In practice
In a discussion about moral philosophy, I might reference this quote to illustrate the complications of imposing beliefs.
The foundation of individual rights is the assumption that people have wants and needs and are authorities on what those wants and needs are. If people's stated desires were just some kind of erasable inscription or reprogrammable brainwashing, any atrocity could be justified.
The linguistic clumsiness of tourists and students might be the price we pay for the linguistic genius we displayed as babies, just as the decrepitude of age in the price we pay for the vigor of youth.
If we are not to abandon values such as peace and equality, or our commitments to science and truth, then we must pry these values away from claims about our psychological makeup that are vulnerable to being proven false.
We adults protect ourselves with laws, police, workplace regulations and social norms and there is no conceivable reason why children should be left more vulnerable, other that laziness or callousness in considering what life is like from their point of view.
The idea that children are passive repositories to be shaped by their parents has been massively overstated. A child's peer group is a far greater determinant of its development and achievements than parental aspiration.
Reason is non-negotiable. Try to argue against it, or to exclude it from some realm of knowledge, and you've already lost the argument, because you're using reason to make your case. ... We don't "believe" in reason.
Tradition does not mean a dead town; it does not mean that the living are dead but that the dead are alive. It means that it still matters what Penn did two hundred years ago or what Franklin did a hundred years ago; I never could feel in New York that it mattered what anybody did an hour ago.
Many a professing Christian is a stumbling-block because his worship is divided. On Sunday he worships God; on weekdays God has little or no place in his thoughts.
Since love of God is the highest felicity and happiness of man, his final end and the aim of all his actions, it follows that he alone observes the divine law who is concerned to love God not from fear of punishment nor love of something else, such as pleasure, fame, ect., but from the single fact that he knows God, or that he knows that the knowledge and love of God is the highest good
To suppress free speech is a double wrong. It violates the rights of the hearer as well as those of the speaker.
The organization controlling the material equipment of our everyday life is such that what in itself would enable us to construct it richly plunges us instead into a poverty of abundance, making alienation all the more intolerable as each convenience promises liberation and turns out to be only one more burden. We are condemned to slavery to the means of liberation.
When a whole nation is roaring patriotism at the top of its voice, I am fain to explore the cleanness of its hands and the purity of its heart.
