My Non-violence  by M.K. Gandhi

I do believe that, where there is only a choice between cowardice and violence, I would advise violence. Thus when my eldest son asked me what he should have done, had he been present when I was almost fatally assaulted in 1908, whether he should have run away and seen me killed or whether he should have used his physical force which he could and wanted to use, and defended me, I told him that it was his duty to defend me even by using violence.
