Martin Heidegger
Nazi and willing accomplice of murder
Answered The Question Concerning Technology
Which purportedly alienates man
From Being in its primordial pristine purity
Or perhaps now and ever opens the door

Technology
Cattle cars
Zyklon B

For the primal truth must be revealed
Unconcealed by way of concealment
As in defeat you beguiled the victors to conceal
Willingly to shroud your crimes in oblivion
Which now and ever cry out to heaven

V2 Wernher von Braun
Bodies tortured and enslaved
ICBM

I will not take lessons in purity
From vile dead Martin Heidegger
