‘Human being is a sign that points in its closure beyond itself.’
This knot has been illustrated in wonderful fashion by Rembrandt (1606-1669) in his painting of Peter denying Christ from ca 1660.
The woman’s hand obscures the light source but thereby points above.
Peter is shown with one hand veiled and the other open. It is the hand exposed to the light which is veiled — which denies. It is the hand extending into the dark which is open.
Peter is the closure (denial) that points beyond itself. The reversed sign. The life there is in death.
