I put forward formless and unresolved notions as do those who publish doubtful questions to debate in the schools not to establish the truth but to seek it.
The result is - document destruction - we're really not going to be able to prove beyond a truth the negatives and some of the positive conclusions that we're going to come to. There will be always unresolved ambiguity here.
What lingers from the parent's individual past unresolved or incomplete often becomes part of her or his irrational parenting.
Also in a funny way if you have been happily married there are no unresolved areas nothing to prove to yourself after the other dies.
