Quotes from Paul Bloom

In politics and in society, we can use our reason to rise above our parochial natures. Too bad that our elected officials don't choose to do so more often.

One way to make a baby cry is to expose it to cries of other babies. There's sort of contagiousness to the crying. It's not just crying. We also know that if a baby sees another human in silent pain, it will distress the baby. It seems part of our very nature is to suffer at the suffering of others.

Morality is often seen as an innovation, like agriculture and writing. From this perspective, babies are pint-sized psychopaths, self-interested beings who need to be taught moral notions such as the wrongness of harming another person.

Natural selection shaped the human brain to be drawn toward aspects of nature that enhance our survival and reproduction, like verdant landscapes and docile creatures. There is no payoff to getting the warm fuzzies in the presence of rats, snakes, mosquitoes, cockroaches, herpes simplex and the rabies virus.

We benefit, intellectually and personally, from the interplay between different selves, from the balance between long-term contemplation and short-term impulse. We should be wary about tipping the scales too far. The community of selves shouldn't be a democracy, but it shouldn't be a dictatorship, either.

Humans are born with a hard-wired morality: a sense of good and evil is bred in the bone. I know this claim might sound outlandish, but it's supported now by research in several laboratories.

Part of the satisfaction of tattling surely comes from showing oneself to adults as a good moral agent, a responsible being who is sensitive to right and wrong. But I would bet that children would tattle even if they could do so only anonymously. They would do it just to have justice done.

Perhaps looking out through big baby eyes - if we could - would not be as revelatory experience as many imagine. We might see a world inhabited by objects and people, a world infused with causation, agency, and morality - a world that would surprise us not by its freshness but by its familiarity.

I'm very interested in why we do good things, or bad things, and where moral judgments come from.

I think empathy can serve as a moral spark, motivating us to do good things. But anything can be a moral spark.

A sympathetic parent might see the spark of consciousness in a baby's large eyes and eagerly accept the popular claim that babies are wonderful learners, but it is hard to avoid the impression that they begin as ignorant as bread loaves.

Imagination tends to be truly useful if accompanied by the power of mental control - if the worlds in one's head can be purposefully manipulated and distinguished from the real one outside it.

Families survive the Terrible Twos because toddlers aren't strong enough to kill with their hands and aren't capable of using lethal weapons. A 2-year-old with the physical capacities of an adult would be terrifying.

Periods of cooperation between political parties shouldn't be taken for granted; they are a stunning human achievement.

The irrationality of disgust suggests it is unreliable as a source of moral insight. There may be good arguments against gay marriage, partial-birth abortions and human cloning, but the fact that some people find such acts to be disgusting should carry no weight.

Empty heads, cognitive science has taught us, learn nothing. The powerful cultural and personal flexibility of our species is owed at least in part to our starting off so well-informed; we are good learners because we know what to pay attention to and what questions are the right ones to ask.

I think what a lot of fiction is, is the imagining of the worst so as to prepare ourselves.

Some scholars argue that although the brain might contain neural subsystems, or modules, specialized for tasks like recognizing faces and understanding language, it also contains a part that constitutes a person, a self: the chief executive of all the subsystems.

Modern science tells us that the conscious self arises from a purely physical brain. We do not have immaterial souls.

Maybe one of the most heartening findings from the psychology of pleasure is there's more to looking good than your physical appearance. If you like somebody, they look better to you. This is why spouses in happy marriages tend to think that their husband or wife looks much better than anyone else thinks that they do.

I don't doubt that the explanation for consciousness will arise from the mercilessly scientific account of psychology and neuroscience, but, still, isn't it neat that the universe is such that it gave rise to conscious beings like you and me?

Any simple claim that you need religion to be good is flat wrong.

We'd be really screwed if we had to start our life over again as children with our brains right now, because I think we lose the plasticity and flexibility.

Once we accept violence as an adaptation, it makes sense that its expression is calibrated to the environment. The same individual will behave differently if he comes of age in Detroit, Mich., versus Windsor, Ontario; in New York in the 1980s versus New York now; in a culture of honor versus a culture of dignity.
