Respect for kids and our bodies is in order
Higher animals have instincts but can also be conditioned. The latter is to sort of learn to react similarly to certain situations without pause. This can be ingrained by things like punishment (fear) and reward. This is because animals already have a built-in sense to flee pain and run after pleasure.
Outright denigrating are mostly well-meaning parents who treat their children this way. They even get convinced it ‘works.’ They punish, and most kids would obey. They praise, and most kids will try to gain again.
Contributing to the resemblance of this working is that obedience and greed/competitiveness are terribly overrated. In a world threatened by anti-democratic laws, rulers, and elites preferring short-term greed over long-term climate survival for all, submission is not always so good. In cultures bent on rivalry and jealousy, being goody-two-shoes can kill.
Some say that humans are much higher creatures than animals, and some say that we are just like any other animal. Both parties are wrong partly. On the one hand, we may choose loftier than animals, to brave discomfort and forgo temptation for a higher calling or principle. On the other hand, much of us functions as animals still. Both aspects we see in all humans.
When we think to condition our children, we disrespect them, as we treat them as if they are subhuman. Of course, they dislike hurt and like reward, but hurting and bribing them is not good parenting. Praise them not as an authority (‘This is good’) but as an equal sharing your feelings (‘I like it’). If you don’t get them or think they made a mistake, ask them (‘Why did you do it like that?’), not to question or criticize them, but because you’re curious and want to help if you could. Your kids are not inferior to you.
Still, we could ask why people must have the lower possibility of getting conditioned. It might be to make biological systems work better. One example: If you’re thirsty and drink until you’re not, you’ve drunk too much. By the time enough water is absorbed in your intestines, still more water from your throat is on its way to being absorbed. If you remove all flued until you don’t have too much anymore, you were still making urine while your blood vessels are not overfilled anymore. A solution to this overshooting is conditioning. Conditioning taught me it will be just enough when I drink so and so much when I got such and such thirsty.
Nice is that, as humans, we can follow our will to trump our instincts and conditioning. We can be thirsty and not drink because it’s Yom Kippur. Animals can only do that when conditioned with fear. Humans can postpone drinking for a good idea that we love. We don’t need fear.
