I disagree. The truth value of a moral claim lies in the objective consequences of the actions it gives rise to. If the acting out of a moral belief can be objectively demonstrated to cause suffering, for instance, then we have to reject its claim to being a "moral" belief in the first place. Consequentially, beliefs and actions cannot in themselves be moral or immoral, but must rather be judged entirely by the consequences they arrive upon other human beings. |
I think our disagreement may to some degree be one of language as opposed to substance. I certainly agree that if we assume some particular goal(s) or valuation(s) we can create a framework with respect to which we might evaluate the truth of moral assertions. The issue is that I find that the nature of this framework necessarily reduces to a matter of opinion.
When you say "logic is only useful in moral decisions if we start with a simple moral norm such as 'suffering is bad' which informs the logical process from the beginning," you are saying exactly what I mean. At some foundational level, we must simply assume some moral proposition (in this case, that suffering is bad.) I do not find there to be any objective basis upon which to judge what, if any, such foundational moral propositions ought to be assumed. If the underlying assumptions cannot be said to be a matter of fact, then what follows from them cannot either. We can, however, still evaluate the validity of the reasoning by which that which follows is reached (if any.)

The parts of the brain that process logic and those that process moral judgements are largely separate, the latter being governed largely by the emotional centers of the brain (lymbic system, amygdala etc.). In fact, those who suffer damage to their amygdala in childhood often display amoral behaviour for the simple reason that they cannot properly read the emotional states of other human beings. So the capacity for empathy, I would argue, is a necessary prerequisite for moral behaviour, while the capacity for logic is not.
That is not to say that actions and moral decisions cannot (or should not) be informed by reason: in fact I would argue that they should. But any moral action guided by reason must also begin with a moral norm that cannot be arrived at via logic alone. That is to say, logic is only useful in moral decisions if we start with a simple moral norm such as "suffering is bad" which informs the logical process from the beginning. Blind logic, however, will not get us very far, as every rational investigation into the nature of morality throughout the history of philosophy has shown us. |
Again, I agree with much of what you say. Moral thinking definitely appears to have its origins in the brain's emotional centers. That is precisely what I would expect of an opinion, however. An individual's favorites, likes, dislikes, et cetera are all likely to be consequences of emotional states...
