An Integrative Look at Nature, Faith and the Human Mind

By Robert DePaolo

Freud once described history as a series of race wars, implying that bigotry is and always has been tantamount to a non-malleable virus infecting all of human society

It is a debatable point. Detractors might say mankind can and typically has learned his way out of racial bias as a result of exposure to, interaction with, and dependence on people of other races. For example in recent times the population of blacks and other racial minorities has increased in western nations, providing support in war and industry and enhancing the national spirit in the arts, athletics and literature.

On the other hand, adherents might contend that built into the human genetic code is an equally non-malleable tendency to protect and preserve the local gene pool, and that stranger-hostility is quite characteristic of all primate groups – including homo sapiens.

Some studies seem to support that view, in particular the work of Wilson & Wrangham, (2003). Their results coincide with a main tenet of evolutionary psychology that primitive behaviors devoted to gene pool preservation will take priority over the egalitarian philosophy framing the rules of social interaction in most democratic societies.

In terms of human experience, “strangeness” does not have to be based on race. It can be based on language differences, ethnic background, gender and any number of real and superficial distinctions. It’s just that the physical differences among races makes the process of discriminating between “us” and “them” rather perceptually and emotionally convenient.

Even with distinctive racial traits, “stranger bias” is hardly inevitable. It seems to be merely one of two options provided by the human brain. As Perry, (2008) and Cromwell & Schultz (2003) have suggested, the sheer size of the brain, particularly in the vast regions of the cerebral cortex (a section less influenced by primal urges and more concerned with learning and integrating new associations and concepts) provides a check and balance on our most basal instincts. Indeed Freud’s theory regarding the separation of the ego from the id for impulse control might have its physiological correlate in the frontal cortex.

In that context perhaps, despite Freud, it is not race, but the human capacity to over-distinguish between objects and persons that comprises the true sociopolitical virus. In truth that process, often referred to as discrimination learning, is more of a two sided coin than a virus because when it comes to drawing distinctions, that component of mind can employed for better or for worse; for example to chart the course of history, politics and scientific discovery, leading either to progress or social devolution.

That all good and bad, productive and destructive elements in society emanate from the human mind is a tautology requiring no further elaboration. On the other hand the way in which the human mind works does invite scrutiny, because the mind/brain is a flexible structure by virtue of its genetic and functional make-up, which can lead to any number of behavioral and attitudinal possibilities. In fact, as Mercado (2008) has suggested, the human brain appears to be a kind of bimodal organ constantly shifting between discriminatory and integrative cognitive processes.

Since human brain evolution occurred in the context of an arboreal lifestyle requiring integrative perception, a capacity for figure-ground (stereoscopic) visual distinctions and internal memory to correct for visual and acoustical vagaries in the trees, it tends to bring ideas together into common focus. In that sense the primate brain template provided us with a penchant for integrative thought. On the other hand the latest primate brain revision providing new circuits to facilitate upright walking seems to have led to a bifurcated human mind, featuring a left-right motor cadence requiring separate inhibition-excitation sequences. This process was converted to other functions and led to an enhancement of discrimination and attention capacities. While all creatures can learn to distinguish between stimuli, the finely tuned alternating/competing capacities to separate and integrate experiences appears to play a significant role in
