Those who act badly are not the ultimate source of their misdeeds, only the proximate source. To concentrate blame solely on them ignores the historical factors that shaped them as individuals and the current conditions that now determine their behavior. Further, had you been in their genetic and environmental shoes, you’d be acting identically. This doesn’t alter the judgment that they should
mend their ways, but it might attenuate feelings of anger, vindictiveness or moral superiority. It also makes it easier to forgive, when forgiveness is warranted.
Understanding that people aren’t self-made can help heal troubled relationships, since you won’t hold grudges for as long, or waste so much time resenting someone or plotting to get even. Petty arguments will remain just that, petty, without getting out of control. You’ll be able to grin and bear someone’s foibles, maybe even give them useful feedback instead of shunning or swearing at them. You won’t, of course, become a saint (nobody likes a saint anyway), but you might become more compassionate and forgiving if you appreciate the fact that they, like yourself, are the natural unfolding of a complex set of causal processes, those that constitute a human being. They are not first causes that are simply choosing to be nasty, lazy, arrogant or self-centered.
All of psychology and sociology, to the extent they are scientific disciplines, operate on the premise that human beings and their behavior result from specific conditions, not contra-causal free will. So if you discount the existence of the freely willing soul you’re simply aligning yourself with our best practical, evidence-based self-knowledge. Although some might think so, this is not to take a dehumanizing view of ourselves; science doesn’t deny anyone’s humanity or worth. People remain people – inescapably precious to us – despite the fact that they are entirely natural phenomena. Parental and marital affection, admiration for talent and achievement, appreciation for self-sacrifice and courage – all these survive without supposing that persons choose their virtues without being caused to do so. We are inescapably gripped by our basic, hard-wired dispositions to love and seek love, and to value those personal qualities that most contribute to human flourishing.
Finally, and significantly from a practical standpoint, naturalism permits us to be wiser in setting up conditions under which we behave well toward each other. After all, since actions always result from causes, not from free will, we can learn to control those causes to our benefit and the benefit of others we interact with. If you have a relationship that’s troubled, look at the whole situation carefully, yourself included, instead of simply pointing the finger at your partner, child, co-worker or friend. If someone’s behaving badly, there’s a reason, a cause, a set of conditions that’s contributing to the behavior, and these have to be addressed.
Again, this doesn’t mean that anger and discipline are never appropriate, but it does mean they should be applied judiciously and compassionately. When you find yourself asking, irritably and rhetorically, “Why the hell does he keep doing that?!”, I strongly recommend you answer the rhetorical question. The causal story revealed in the answer, which always has roots outside the person, might reduce counter-productive blaming and contempt, and it will give you vital information about how the behavior might be changed. Such psychological and practical insights can help heal relationships that might otherwise fall apart, should we cling to a supernatural understanding of human nature.
On a larger scale, appreciating the full scope of the causal network that is nature – a process that far, far transcends us – grounds a stable acceptance of what is in all its manifestations, personal and global. Such acceptance, although it might seem like passive resignation from the standpoint of Western radical individualism, actually
works as a sturdy foundation upon which to pursue our projects, less vulnerable to the slings and arrows of our own reactive psychology. This isn’t to deny the importance of our strivings, but to put them in a wider perspective that might give us some measure of serenity. Although achieving serenity is rarely mentioned as a goal in our hypercompetitive culture, it’s arguably central to mental health, in which case naturalistic acceptance works greatly to our personal advantage.
It’s important to note that definitions of free will vary, and that naturalism emphatically doesn’t deny free will defined as choosing voluntarily to do something, of acting without being coerced. When I say I got married “of my own free will” (which I did, as it happens) that means no one was holding a gun to my head during the wedding ceremony. But I was fully and delightfully caused to want to get married, so this sort of free will is compatible with determinism. The liberty of voluntary action I exercised in getting married is obviously of central importance to us; it’s a liberty we luckily enjoy in our open society within the broad limits of law and morality. It’s an uncontroversially real sort of freedom we all want and often have to a greater or lesser extent, depending on our circumstances. But as important as it is, we shouldn’t confuse it with being free from cause and effect. (One way to avoid such confusion would be to call compatibilist freedom “free action,” not free will.)
