'Die Gehaltene Hand' at Marwan, Amsterdam

Is a hand that is being held supported in the action of holding for its own increasing weakness? 

Or is a double support of holding just twice as strong? A hand that is held by another is the 

beginning of a system or an architecture. Why would a hand be held by another? Out of love and affection? 

Or more out of pity and compassion? Held hands are a hot-blooded structure.
