You don't have to teach aesthetics on the same level as adults or philosophy on
an adult level for that matter. Children can and do think abstractly when they
are encouraged and guided to do so. This does not have to be at a high level
of abstraction, but can easily be brought to their level. I have been doing it
each summer for three years now. There are specialists in Philosophy for
Children who are especially trained for this. My hope in providing the
resources I mentioned is to give those educators who have not had such training
some assistance. Art is a wonderful tool for this kind of thinking. Gareth
Matthews doesn't talk about content but about our approach. It would be worth
your while to look into it.
P.S. I don't know why my email sometimes duplicates my post. I still haven't
figured out this particular quirk.
