What morality means to me – what I strive for – is that I can never rank the value of my life above that of anyone else’s life. As a humanist, I think this is easy to do. (Indeed, I think it’s the logical conclusion of rational mind.) As a convicted murderer, I will forever be looking up. I do believe that there are people out there who’re much worse than I am, and therefore their lives are less valuable than mine. But this is only because they themselves have lowered the value of their lives through the victimization of others, not because I have elevated mine above theirs. As someone who strives to be moral, I refuse to do that.
If I think that everyone’s life has equal (or more) value than my own, I cannot possibly justify victimizing anyone, ever, for any reason. I will not claim to be selfless human being – but I willclaim as my moral goal to never base the value of another’s life on my own interests.
This does not, however, mean that I will abdicate moral responsibility and judgement. I can’t do that and expect to be a moral person. No moral human being can reserve judgement, or they would walk on by as a child gets beaten to death. Anyone with the tiniest kernel of moral sense can make definitive judgements such as, “I’m better than that person. I’ll fight him to put a stop to it.”
As a humanist who doesn’t think there is any divine moral standard, I’m still capable of absolute judgements about the value of human life. For example, though I accept the evidence for the theory of evolution, this doesn’t mean I think there is anything moral about it. We can’t look to natural selection for gauge of life’s value, because the only thing of value to natural selection is passing on one’s genes. In this case, the mot valuable people would be the ones with the most children. Sexual slavery and no birth control or abortion would be the hallmarks of a “moral” society (similar to life under Old Testament laws, ironically.)
The age-old and extremely common methods of valuation such as ethnicity, nationality, and skin color are simple prejudices. They do not determine anything meaningful about the value of a human being’s life. Indeed, they are the height of irrationality, since these concepts become meaningless if you trace humanity back far enough into it’s past. Gender doesn’t work either. One doesn’t have to be a radical feminist to understand that whether a person has a Y chromosome or not says nothing about their intrinsic value as a human being.
Productivity (how much a person produces in their life, in the form of goods or services for others) is also out. It makes for a neat little synthesis of laissez-faire capitalism and evolutionary theory, but it obviously cannot be accepted as a moral standard. A serial killer might be an extremely productive individual. Indeed, perhaps his victims are people who refuse to produce anything. Not only would he be a great producer himself, but he would be helping general productivity by removing those who only consume the work of others. Besides, you can’t objectively measure someone’s potential productivity – a person might be unproductive their entire life, yet later produce a great product or service that eclipses many others.
None of these methods for measuring the moral value of human life are any good. In fact, you can be pretty sure that if someone is using one of these methods, that person is a good example of what is not moral.
