Others point out however that "there does seem to be a basic ambiguity in Jung's various descriptions of the Collective Unconscious. Sometimes he seems to regard the predisposition to experience certain images as understandable in terms of some genetic model" – as with the collective arm. However, Jung was "also at pains to stress the numinous quality of these experiences, and there can be no doubt that he was attracted to the idea that the archetypes afford evidence of some communion with some divine or world mind', and perhaps 'his popularity as a thinker derives precisely from this" – the maximal interpretation.
