Unselfish concern for others (8)
I believe the answer is:
altruism
'unselfish concern for others' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for altruism that I've seen before include "Unselfish generosity" , "Unselfishness found in ultraism" , "Selfless concern for the well-being of others" , "Unselfish action, generosityfor its own sake" , "Unselfishness shown by muralist" .)
