Scientists have carefully studied the subject of 'Phrenology' ( determining characteristics and abilities by studying the bumps on the human skull) and as a result of their findings are about to publish an extraordinary fact.
It would appear that prolonged acceptance of the information received from ANY source other than that which one perceives and analyses independently, can be of detriment to the recipient.
Thus, if one readily accepts that the information received is correct and true, the bumps on the skull are less likely to develop and the end result is that the person becomes an easy prey to any that would wish to manipulate their thoughts and actions.
As one eminent scientist put it "It could explain the reason for why some humans are far more susceptible to hypnotism than others and furthermore, why in some cases (the majorities) are so easily convinced by those who wish to control them that ANY comment they make MUST be true, since it is accepted BY the majority."
I find this particular statement extremely interesting since, if each individual were to consider the source (retrospectively) of their own characteristics and abilities, I do wonder if the main influence of their current beliefs/actions/opinions stemmed from their parents, tutors OR (most likely in my own opinion) those shadowy figures in government who daily seek to FOOL the majorities and thus maintain power.
Such analysis of one's SELF might reveal the reasons for why there is so much disharmony among humans.
A simple test to determine whether or not one has become (shall we say victim ?) so moulded by those outside influences, is to gently feel the contours of one's head, the flatter it is, the more one has suffered.
Simply put, if one wished to insult another person, particularly in terms of their lack of intelligence/knowledge/etc, one would usually remark that their head was full of 'Sawdust'
I think a more accurate or suitable diagnosis of their unfortunate condition (if justified of course) would be to remark that their head was full of 'Newspapers'
