Suppose for a minute we are brothers, you and I. Suppose our mother has been attacked by a terrible disease. In the course of fighting the illness, our mother has become addicted to the drug which was prescribed to cure her. Now imagine that one of us feels that the medicine is doing her more harm than the disease and is struggling to get her off of the drug, while the other is convinced that she will surely die if she stops taking her medication, and fights to keep her taking it. Can we say that one of us loves his mother more?
