The above has a kind of 'truth is contained in propositions in the brain that mirror reality'. But propostions do things. Thinking of them as containers that mirror reality, apart from the philosophical problems with this, certainly misses what truths do.
So you have these kids and the same truth (theoretical) in two kids may do different things.
You've got these creatures coming into the world, and the best thing is if they have beliefs that work well for them. Propositions in their minds that create a nice, dynamic interaction with life that works, for them, as individuals.
I mean, for example, you might think it determinism is true, mechanistic conceptions of the human brain are correct and one kid finds this fascinating becomes a neroscientist - never for a second brooding over the potential or necessary lack of free will - and tinkers with nervous systems and rat brains and just loves his life. Then you might have another kid who this belief makes feel bad.
To me a more constructivist, let's get the kid to bloom approach is more respectful.
This does not mean testing out a variety of beliefs one does and does not have on kids and seeing where they bloom, but getting out of the way of their forming beliefs, where possible. I mean you state yours, of course, on occasion.
