The general notion espoused by the worlds’ religions is that all humans are equally endowed with the capacity to resist temptation, to inhibit desire, to put aside urges in favour of a set of values and principles. Our ‘salvation’ is dependant upon this... Those who don’t are labelled as sinful, deviant, executed, beaten, experience social isolation, both under religious paradigms and within our current world view. What neuroscience points to is that our ability to resist or rather inhibit is reliant on an organic mechanism implemented in fronto-striatal network, and is dependent on a sub-class of neurotransmitter systems. This has been demonstrated within rodent, non-human primate as well as human models of inhibitory mechanisms. Pharmacological manipulations and studies with knock-out mice have even pin-pointed receptor subtypes within this network underlying inhibitory control. There is also evidence that suggests that specific electrophysiological and behavioural markers exist in a premorbid state.
The development of this network is constrained by genetic factors and shaped by experience. Just as some people are short, some tall, some dark, some light, our capacities to resist temptation are different. We are not all on par when it comes to dealing with desires as organised religion and many of the modern institutions would have us believe. If this is so then why should a blanket set of moral standard be extended to all humanity both in the form of religion, and the religious hangover we call the post-modernism world? It is simple, the condition of the front-striatal organic network constrains the inhibitory capabilities of an individual. This means that we are all different, not everyone has to same scope to express their inhibition of desire. This suggests that moral choice is dependent on an organic mechanism, there is no gold standard for all humans, there is no form of spiritual strength, a bad ‘moral choice’ is not part of person ‘personality’ and a ‘deficiency’ from earlier life. It’s simply a state of an organic mechanism constrained by genetics and shaped by experience.
Perhaps it is then time to shed false judgements of others? For if a human doesn’t have the capacity to inhibit equal to others then why should we cast judgement down on them, as true choice doesn’t exist in this instance. Can you judge a tree as good or bad for growing or not growing a branch, can you judge a clover as good or bad for only growing two leaves? Of course not… in the same way another human can’t cast judgement on another human for the state of an organic network. It’s not a matter of exercising choice, as the same scope of choice is not equal for all humans.
The reductionistic view of morality has the capacity to drastically change the way we view aberrant behaviour in human society, as well as how we heal and forgive one another. Perhaps we would withhold judgement and cast a gaze of compassion and understanding knowing that there is no such things as sin, no such thing and poor moral reasoning, just behaviour that is a consequence of an organic physical mechanism. Perhaps we could understand this mechanism in greater detail and learn how to train it, optimise it pharmacologically in those who require such optimisation, and thus reduce the suffering and false judgements within human society. Perhaps we could forgive more easily knowing this to be true…
