@Diane,
Dys was deep, and this is no criticicism of his memory, but he wasn't Nietzche.
He was an extremly well read, highly opinionated, original thinker.
His passing is a major loss.
I would very much have liked to meet him him even if one of us might not have left the meeting alive.
Again, my sincere condolences. My bet though is that he left you with a wealth of memories to draw upon in your grief.
