His ideas drew criticism from the moment they first circulated, and those objections continue, even as psychologists still regularly cite his work with considerable respect. Because his output was so extensive, it seems fitting to look closely at the inconsistencies and gaps in it, along with the competing interpretations that have been raised and are still being debated.
