Our nature is innate; our feelings are influenced. The basic nature of all people; of all races; of all cultures; in every place and of everytime; is and always has been the same. Our natural inclination is to be sensitive to the pain and suffering of others. When we don't have time to rationalize a situation, then our natural inclinations rule the moment. Hence, we swerve to miss that dog in the road. Hence, we hate the sight, or even the thought of another in pain, physical or otherwise. These natural urges that come from within are our innate nature internally acting upon our feelings.
Feelings are influenced. Feelings can lead to actions and to attitudes which are good or bad, for feelings are subjective to influence and open to our free moral agency. In other words, we can think anyway that we want and do whatever we please. Hence; we can remain in compliance with our innate nature, or act contrary to and thereby compromise our basic nature of sensitivity towards the pain of another.
Therefore, we can on the spur of the moment say unkind words to someone who has "hurt our feelings". Thus, we can rationalize the ethic of a society that allows concentrated wealth for some while denying healthcare for others. My goodness, we can even find a way to justify the torture of another human being in the name of a "righteous" cause.
We can rationalize all day long our words, our deeds, our beliefs, and our philosophies within the framework of our conditioned beliefs. The question is; shall we comply with and abide by; or shall we compromise and act contrary to our basic nature of human decency?
