Well, if truth is so subjective, then I suppose you have to decide which type of morality you want to practice. Indeed, tossing aside the objectivity of truth opens up a variable smorgasbord of delectable “isms” not readily available to Christian Moral Theologians. And you don’t have to choose just one. You can keep them all in your moral toolbox for later use as needed.
Do you want to be a Relativist? You know “When in Rome, Do as the Roman’s do” or “That’s right for you.” For the relativist, moral reality is not objective, but subjective. Circumstances and personal choice are all that are needed to justify one’s actions.
Do you want to be a Hedonist? “If it feels good, Do it” For the hedonist, the goal is to you freedom in a way that maximizes pleasure for the self. A life full of pleasure is a good life.
Do you want to be a Proportionist? “Benefit > Cost = Choice” For the proportionalist, moral decisions are made based on a cost benefit ration. If the benefits of a certain action outweigh the cost, then it’s the right thing to do.
Do you want to be a Utilitarianist? “The greatest happiness for the largest number.” For the utilitarian, the goal is to use freedom in a way that maximizes pleasure for the many. A society where most people experience pleasure is a good society.
Do you want to be a Legalist who adheres to Divine Command Theory? “God said it, I believe it, That settles it!” For the Legalist, moral decisions are made on the basis of rules imposed by authority. When making moral decisions, law is absolute and must be followed to the letter. Circumstances or reason do not mitigate this obligation of law.
Do you want to be an Individualist or Egoist? “Looking out for Number One” For the individualist, moral decisions must be made on the basis of personal freedom and independence from others. Actions which benefit the needs of the individual over and above the needs of others are always moral. Inter-dependency with others is to be avoided because it limits personal freedom.
Do you want to be a Behaviorist? “I just couldn’t help myself” Behaviorists believe that human acts are solely the result of nature and conditioning. To act according to one’s nature or programming is amoral. If humans are not fully free, they cannot be fully culpable in moral matters.
So, as you see, without the constraints of objective truth, you have a lot to choose from.
