voretus is correct this is not an appropriate external link i have checked the guidelines and think this link is highly relevant also i want to add that i haven t found a better article which tackles 'ontogenesis recapitulates phylogenesis' postulate there are also some extremely important quotes about jung's nazi involvement i think the link is worth just for those quotes check the notes i think they are highly relevant to the whole corpus i am sure they cannot be included in the main encyclopedia article but a link serves good in such a case please correct me if i am wrong
