This assertion that 99% of all HUMAN BEHAVIOR is mechanical seems to most to be rather absurd, although many, if not most contemporary peoples will concede that ANIMAL BEHAVIOR IS 'INSTINCTIVE' and also claim that human behavior is 'willed'.
MECHANICAL BEHAVIOR is 'unconscious' , 'unthinking', 'impulsive', 'incidental' , and 'occasional' or 'automatic' as the case may be, ORDINARY HUMAN BEHAVIOR, often confused for 'normal' behavior, involves the BODY, of course, but also THINKING & FEELING; the 'MIND'
and the 'EMOTIONS' among other things, but you and others like you, who read this are not apt to
understand this for quite a while, if at all during your present lifetime, for a great many reasons.
Your physical behaviours, your mental behaviours, and your emotional behaviours are not in your full control, that is, you do not see the connections between these BEFORE they begin to operate and you take each SITUATIONAL EPISODE as such, confusing feelings and thoughts, for example, relying on such things as 'I LIKE', 'I DISLIKE', 'I LOVE', 'I HATE' , ETC.
These 'positions', 'stances', 'poses', 'states', 'conditions', etc. are RELATIVE and changing, sometimes continually doing so, other times gradually, but seldom are static and rigid unless they form and freeze into specific attitudes or 'fixations' , 'phobias' and the like.
For the most part, you do not remember these 'states' unless they are 'overwhelming', such as an illness affecting the body, mind and emotions in some general or specific way, and examples of all this are extensive, especially in modern society in the UNITED STATES. The number of pills and drugs taken on a daily basis by people in the US, which can go to amounts like thirty or more per day, and the growing 'health care services' of all types, both traditional, orthodox, standard, mainstream and the 'fringe', alternative, 'drugless' and 'natural' are indicative of health and disease issues in many nations.
INVOLUNTARY ACTIONS, whether physical, mental, or emotional are responsible for all the ills and evils in human society, culture, nations, etc. despite all 'rational' and 'reasonable' plans created and set up to solve these problems.
SINGLE SOLUTIONS to COMPLEX as well as to 'SIMPLE' PROBLEMS seldom work or if they do, not as efficiently as hoped for or planned, let alone promised, especially by governments.
Someone or something, in these terms, 'always throws a monkey wrench in the works'.
A good example of this is a bomb thrown into a gathering or a crowd by a terrorist. 9/11 is an example where people driven by their usual habits and concerns, their fantasies and whims, and their involuntary behavior died.
Those who responded to this incident to save lives and to bring order to chaos ,etc. and who either lived or died are now 'heroes' and those who died are now 'victims'.
This illustrates NOT predestination but THE LAW OF ACCIDENT. Those who did not go to that
area, or to work there, etc. in that building, for whatever reason, survived and those who did not respond to the event also. But that simple fact is ignored as the REACTION(S) to this EVENT have taken over.
But the world sees many 'tragic' and 'heroic' events and deeds as well as many 'births' and 'deaths' on a daily, even hourly basis that our bodies, minds, and emotions cannot take in, that they ignore, of which these 'machines of mind, body, emotions, are ignorant and unaware, and actually helpless to deal with on many levels and scales.
THUS, the death of one person is apt to be a tragedy for his family, friends, associates, and relatives or neighbors, if that person has any, while the death of MILLIONS, whether by war(s), disease(s), starvation, extreme weather, volcanic-earthquakes-tidal waves etc., or by auto accidents or mass suicides are merely statistics.
