{∅, {∅}, {∅, {∅}}} : Rage Against the Meat Grinder

In anxiety one feels uncanny.Here is the peculiar indefinateness of that which Dasein finds itself alongside in anxiety,comes  proximally to expression:the "nothing and nowhere".But here uncanniness also  means "not being at home".In our first indication of the  phenomenal character of Dasein's basic state and our clarification of  the extential meaning of  "Being-in" as distinguished from  the categorical signification of  "insideness",Being-in  was defined as "residing  alongside..","Being familiar with...".
This  character of Being-in  was then brought  to view more concretely through the  everyday publicness of the "they",which beings  tranquilized self-assurance-"Being-at-home", with all its obviousness-into the average everydayness of Dasein.On the other hand,as  Dasein falls anxiety brings it back from its absorption in the "world".Everyday familiarity collapses.Dasein  has been individualized,but individualized as being in the world.Being-in enters into the existential "mode" of the"not-at-home".Nothing else is meant by our talk about"uncanniness".
