The entire civilized world knows that the first two or
three years of association after marriage are often marked by much
disagreement, of a more or less petty nature. These are the years of
"adjustment."
If the marriage survives them it is more than apt to become a permanent alliance. These facts no experienced married person will deny. Again we see the "effect" without understanding the "cause." While there are other contributing causes, yet, in the main, lack of harmony during these early years of marriage is due to the slowness of the chemistry of the minds in blending harmoniously.
Stated differently, the electrons or units of the energy called the mind are often neither extremely friendly nor antagonistic upon first contact; but, through constant association they gradually adapt themselves in harmony, except in rare cases where association has the opposite effect of leading, eventually, to open hostility between these units.
It is a well known fact that after a man and a woman have lived together for ten to fifteen years they become practically indispensable to each other, even though there may not be the slightest evidence of the state of mind called love.
Moreover, this association and relationship sexually not only develops a natural, affinity between the two minds, but it actually causes the two people to take on a similar facial expression' and to resemble each other closely in many other marked ways.
Any competent analyst of human nature can easily go into a crowd of strange people and pick out the wife after having been introduced to her husband. The expression of the eyes, the contour of the faces and the tone of the voices of people who have long been associated in marriage, become similar to a marked degree. So marked is the effect of the chemistry of the human mind that any experienced public speaker may quickly interpret the manner in which his statements are accepted by his audience.
Antagonism in the mind of but one person in an audience of one thousand may be readily detected by the speaker who has learned how to "feel" and register the effects of antagonism. Moreover, the public speaker can make these interpretations without observing or in any manner being influenced by the expression on the faces of those in his audience.
