The average Jo Blo simply follows his instincts, poor as these unconsciously accumulated millions of years of ancestral experience may be, he sometimes succeeds and at other times fails. He puts the outcome down to the mythical entity, “luck.”
The more sophisticated and virulently ill in the mind, tend to imagine threats that do not in fact exist and then set about complex and devious plans to harm the world to feed their unfounded fears. In so doing they succeed in manufacturing very real threats that did not previously exist. This does no one any favours.
Self-preservation, so called, is a valid instinct when it does not become rampant, predatorial and a harm causing pathological state addicted blindly to vampiric habit tendencies.
Conversely, the overly pious, in their imagination, have been heard to propound “self preservation” as somehow, “bad,” on the basis that there may be a measure of fearful roughness and discomfort involved. But when the chips are down, these have been noted, just like everybody else, to either seek to run, or to stand up and fight. Albeit mostly too late from lack of preparation.
