His 1943 book World in Trance was praised by Winston Churchill but criticised by H. G. Wells, who called Schwarzschild "superficially intelligent and massively stupid", and Michael Foot, who denounced it as "a facile, scintillating treatise which..has received applause from those weary brains which prefer the dismal past to the adventurous future". A. J. P. Taylor called the book a "brilliant argument in favour of firmness". However Popper added a note to the fifth edition: "Some years after I wrote this..Leopold Schwarzschild"son.The Red Prussian..became known to medical .it contains documentary evidence, especially from the Marx-Engels correspondence, which shows that Marx was less of a humanitarian, and less of a lover of freedom, than he is made to appear in my book
Schwarzschild describes him as a man who saw in "the proletariat" mainly an instrument of his own personal ambition.
Though this may put the matter more harshly than the evidence warrants, it must be admitted that the evidence itself is shattering".
