“Marks is so eager to divest himself of anything that sounds like morality that he says there’s nothing we should do because there are no moral ‘shoulds’, only what we want to do – a view of human nature that he calls ‘desirism’. All we ever do is what we want to do, he says. So the goal of his work is to convince us to desire amoralism.
In this effort Marks succeeds brilliantly. His chapter entitled ‘Might Amorality Be Preferable?’ includes an excellent rant against the defects of our typical sense of morality: morality makes us angry; it promotes hypocrisy; it encourages arrogance; it’s arbitrary, because there is no final justification for saying anything is right or wrong; it is imprudent, leading us to do things that have obviously bad consequences; it makes us intransigent, fueling endless strife; it is useless as a guide to life; and it leads philosophers to waste time on silly puzzles. By contrast, amorality is free of guilt, tolerant, interesting, explanatory and compassionate when the blinders of blame are removed, we are free to consider others with an open heart, not to mention true. The upshot is that amorality is far more preferable. If you read only this chapter, you will have gained a lot.
Marks is here making a meta-ethical claim – a claim about the status of ethics – which claim I like to explain in terms of the language used to express it. That is, throughout the history of philosophy there have been two competing domains of discourse regarding ethics and morals, the Right and the Good. The Right pertains to duty and obligation: it refers to an obligation to obey moral rules; laws that are taken to be applicable universally and independent of one’s own preferences. The Good pertains to benefits and harms: it refers to consequences of actions that may be good or bad for the agent or others. In these terms, Marks’ claim which I find persuasive is that Goodness trumps Rightness – that it makes more sense to speak of ethics ie, ideas of the best way to live in society in terms of benefits and harms than to speak in terms of duty and obligation.”
