There are levels of validation for the concept of ‘proof’, and many proofs are produced by the structure of arguments rather than by direct observation, experiment and … adventure. There are some aspects of ‘that which is’ that only appear during certain kinds of human or organismal participation. These will be found ‘to not exist’ in any context where those forms of participation, agreement and interaction … are missing, counterfeited, too narrowly defined or otherwise ‘tested’.
