There is given [es gibt] the Nothing in spite of the fact that beings are. And perhaps it is one of the greatest of human errors to believe oneself always secure before the Nothing so long as beings can be encountered and dealt with and retained. Perhaps the predominance of this error is a main reason for blindness vis-à-vis the Nothing, which cannot affect beings, and least of all when beings become more and more ‘existant’ [seiender]. Perhaps the belief that the Nothing is just ‘nothing’ is also the main support for a popular piece of intelligence, namely: every reflection upon the Nothing leads to nothingness and endangers the legitimate trust in beings.
