nothingness

The state of nonexistence; the condition of being nothing.

A thing of beauty is a joy for ever: / Its loveliness increases; it will never / Pass into nothingness; but still will keep / A bower quiet for us, and a sleep / Full of sweet dreams, and health, and quiet breathing.

In 1928 [Martin] Heidegger succeeded [Edmund] Husserl to take a chair at Freiburg and in his inaugural lecture made a pronouncement that earned him a reputation as an archetypal metaphysician with his claim that our awareness of people as a whole depends on our experience of dread in the face of nothingness.

A void; an emptiness.

The quality of inconsequentiality; the lack of significance.
