Morality is a social construct, but so are notions of identity and self. Upon reflection, psychology, a discipline I already hold in the lowest regard, is only the minutest subset of sociology. Without society, psychology would have nothing to study.
Sociology is more focused on structure and interrelationships whilst psychology concerns itself with the individual agent’s psyche. Sigmund Freud did recognise this by the taxonomy of id, ego and superego. It seems that by Freud’s reckoning, the id is a stand-in for volition, rather unconscious reactions, whereby the ego is more reflexive and tempered by the external world. Employing this model, in at least one way of thinking, the id represents the bare and authentic self whilst the ego is the accumulation of inputs.
Put in causa sui terms, the id is the result of inherited genetic temperament and the ego is the result of societal forces as interpreted by the id and any antecedent ego.
Remember, one function of the brain is as a Bayesian prediction engine that evaluates new inputs and forms a new sense of perceptual reality and fitness to operate in this universe.
Freud’s superego is ostensibly a part of the ego gone underground—, most of it operating beneath the surface. It’s what I’ll consider being the Nancy Reagan of the psyche—just say no*. It’s Jiminy Cricket. Apologies for not having more contemporary conscience references. I suppose my age is showing.
According to Freud, most of who we are is a social construct, save for the kernel of the id, the proto-self. The ego is the part almost—but not all—above the surface, manifest in consciousness. Conversely, the superego has the reverse configuration, existing almost entirely below the surface. One might even be tempted to argue that the portion of the superego above the surface has actually already been assimilated into the ego.
So, we’re animated sausages, skins stuffed with social cues. Some of these social cues are also moral codes, but many moral codes are inherently unstable and vary by context. And there are local and global morality sources. For example, most religious doctrine is local, so a text authored by a venerated leader in one area may not be venerated outside of that context. In some cases, the directive contains no moral content—don’t eat pork or shellfish or take Saturdays off—whilst others do—love thy neighbour as thyself. Still, they are all social constructs.
If one has no interactions with the other culture, these societies can coexist without challenge, but when a ‘take off on Saturday’ group intersects with a ‘take off Sunday group’, there may be friction, each chiding the other for their nonsensical belief in the manner of Dr Seuss’ Sneetches.
Given this, when discussing morality, we are forced into a structure built on shifting sand. The challenge is that some people believe this ground is bedrock, and power structures insist it is in order to leverage a more solid foundation to maintain power and control.
If we are in some milieu, we are then forced to comply with their norms and morés or be cast out or marginalised, perhaps even scapegoated as Girard might suggest.
Meantime, just take morality with a grain of salt and remember that as will all things human, there are flaws in the logic and outcomes. Also understand that even if these outcomes are flawed and you need to participate in that society, you probably need to remain under the radar—easier for some than others—, conform, play the eccentric, or perish.
