Words of the jargon sound as if they said something higher than what they mean.

The jargon makes it seem that ... the pure attention of the expression to the subject matter would be a fall into sin.

Elements of empirical language are manipulated in their rigidity, as if they were elements of a true and revealed language. The empirical usability of the sacred ceremonial words makes both the speaker and listener believe in their corporeal presence.

The important thing is not the planning of an Index Verborum Prohibitorum of current noble nouns, but rather the examination of their linguistic function.

The jargon of authenticity ... is a trademark of societalized chosenness, ... sub-language as superior language.

In a world that has been thoroughly permeated by the structures of the social order, a world that so overpowers every individual that scarcely any option remains but to accept it on its own terms, such naiveté reproduces itself incessantly and disastrously. What people have forced upon them by a boundless apparatus, which they themselves constitute and which they are locked into, virtually eliminates all natural elements and becomes “nature” to them.

If philosophy is still necessary, it is so only in the way it has been from time immemorial: as critique, as resistance to the expanding heteronomy, even if only as thought's powerless attempt to remain its own master and to convict of untruth, by their own criteria, both a fabricated mythology and a conniving, resigned acquiescence. ... It is incumbent upon philosophy ... to provide a refuge for freedom. Not that there is any hope that it could break the political tendencies that are throttling freedom throughout the world both from within and without and whose violence permeates the very fabric of philosophical argumentation.

Being, in whose name Heidegger’s philosophy increasingly concentrates itself, is for him—as a pure self-presentation to passive consciousness—just as immediate, just as independent of the mediations of the subject as the facts and the sensory data are for the positivists. In both philosophical movements thinking becomes a necessary evil and is broadly discredited. Thinking loses its element of independence. The autonomy of reason vanishes: the part of reason that exceeds the subordinate reflection upon and adjustment to pre-given data. With it, however, goes the conception of freedom and, potentially, the self-determination of human society.

The more reified the world becomes, the thicker the veil cast upon nature, the more the thinking weaving that veil in its turn claims ideologically to be nature, primordial experience.

Philosophy ... must not bargain away anything of the emphatic concept of truth.
