On what basis could you possibly make this claim? Freud had a hundred crack-pot theories that were no more than conjecture, but stated with the auhority of sceintific absolutism. Just because Freud said it was so, and a bunch sheep followed his tone of auhority, does not mean that Freud was a man of reason. It he seemed quite the opposite to me.
Now Jung had some mysticism about him, but certainly no less than Freud, and I would say that Jung's ideas probably came closer to the reality of how the mind works, having described it has a machine of modular, functional process of varrying abilities.
Jung also wasn't so completely obsessed with sexuality, so he didn't overmphasize it, nor was he quite as prone to label things pathological. Freud did it left an right.
And from here on out, let me say that I don't care about how Freud or Jung related to the Nazis, because that doesn't say anything about the legitimacy of their theories.
