I’m compiling some questions as I go along reading about brain function, sensory functions and other key participants in human-animal life. We encounter ideas over and over, which we gloss over, as “reasonable” or which correlate to “how things work,” but sometimes an assertion suddenly seems very odd.
- Even though certain genes are implicated in depression, they do not seem to trigger this illness inevitably. Instead, they simply transmit a susceptibility to falling into depressive states more readily—a greater likelihood that given the individual’s particular personality traits, or a particular external event, he or she might develop clinical depression.
Just how does a gene do this? We read that genes predispose a person to X condition, but what does this mean? Do genes have an On / Off / AND a Maybe switch?
Does our personal DNA unfold like Schrodinger’s dead/alive duality? Our DNA is “generic” – that is, 99.9% like every other Homo sapiens – and we exist in a type of identity limbo until “something” within us (the ghost again) or event(s) in the environment (trauma, opportunity), “open the box” to create-reveal our genetic “state of expression” or as psychology sees it, individual human identity is pathological.
Nature’s great generator (evolution) of non-identical creatures as opposed to clones, is denigrated: the power of sexual reproduction IS the churning and mixing of DNA – of “mistakes” that mostly can’t be “judged” until tested by changes in environments. Adaptation requires that organisms change – psychology insists that the “edges” of humanity are not only useless, but dangerous, which is a very short-sighted stance against adaptation-evolution.
