This quote is talking about the ever-present interior battle that we all have inside ourselves. We are constantly faced with decisions, and our own personal views and opinions can pull us in different directions. This struggle can make us feel like human life is the continual struggle of debating within ourselves; trying to reconcile our wants and desires, while also considering what is right or wrong. In other words, we are often forced to balance our intuition and desire for certain things and our moral code.
