Does today's society support kant's contention that minors are not conditioned to think for themselves?

Today's society does support Kant's claim. Minors are not released unto the world, so to speak, until they are eighteen. They cannot drive until they are sixteen. They cannot move on until, scientifically, their brain has developed enough that their decision making is not clouded by emotions and pressure from others. Even in universities, students are guided along. Minors and not conditioned to think for themselves at first at all. Children are guided by their parents and family to do the right things. until they get older, then they can start to think for themselves. At first, though, they are conditioned to listen to their parents, who inherently know more than they do.

we should all just get dogs.

yes, we appreciate these things!
