He complains that Heidgger’s language is “metaphorical and contorted to the point almost of incomprehensibility” so that no one can “understand [it] completely”. Furthermore, Heidegger “does not give any arguments for the truth of what he says,” relying instead exclusively upon “compound assertions, with hardly a ‘thus,’ ‘therefore,’ ‘possibly,’ or ‘it might follow that,’ to indicate the relations which are supposed to hold between them.” “Even if the whole of Heidegger’s philosophy is both meaningful and true, therefore, we have yet to be given a reason to accept it. Looked at critically, Heidegger’s ideas seem like spectral visions in the realm of thought; vast, intangible shadows cast by language”.
