Dear Stan, lists - Good. I tend to side with Peirce here - though I would change the wording slightly: logic exising "outside" of human thought, meaning logic existing independently of human thought (which is why it may be implemented, to some degree, outside of human thought) … Best F

This can bee pared thus using a subsumptive hierarchy: (objects {confronted by reactive system {using principles of logic}}} which can read as a developmental/evolutionary sequence. The form of this is a tree with its root, here, in 'objects'. A consequence of this is that, since logic is a property, as far as we know, only of some? human cultures, the innermost branches get pruned to but very few. However, Peirce believed that logic existed outside of human thought. Taking up that position, the tree can grow again, but the logics at the tips will not be the same as in few that survived pruning above. That is, there must be many forms of logic, not only the versions in a single tradition, which was Peirce's logic as well.
