No figures in the history of human thought got it as wrong as Freud and Marx

They were both great writers and towering intellectuals, but like us all, Freud and Marx,  were victims of their age - as were the people who at one juncture in our history thought the world was flat.

So what is the present day reward for these two towering intellectuals.

The received opinion of today is that: no two figures in the history of human thought were more wrong about all the social and mental fundamentals. 

So it is scant reward from posterity.
