Repressed sister fixation like repressed mother fixation has been found on several occasions as one of the components of homosexualism in the man, father or brother fixation as one of the causes of frigidity in the woman.
=Blood Relations.= Mother or sister fixation is frequently the cause of marriage between blood relations. This sort of union has been unjustly suspected of breeding mental inferiors. We should rather say that it is the mental inferiors who seek their mate within the family circle. Unable to secure the mother or the sister as a mate, they select a woman who has as many of the family traits as possible, that they may feel more secure in her company. If a defective child is bred of such unions, it is not due to the close relationship of the parents but to the fact that too often one of the mates was deficient physically or mentally.
In this respect as in many others, self-knowledge and acceptance of one's personality, coupled with a courageous understanding of unavoidable biological facts, are the necessary conditions for perfect mental health and freedom.
The man with a mother or sister fixation, the woman with a father or brother fixation should be made aware of it, however slight or severe the fixation may be.
They must be made to realise that incestuous cravings are biological phenomena which for reasons of convenience have been made unlawful but which do not brand the individual experiencing them as a degenerate or a vicious person.
They must also be made to realise that their incestuous craving may be one of the symptoms of the neurotic search for the line of least effort, knowledge of which weakens the craving to the point of insignificance.
The individual with a biologically real incestuous fixation should accept it and seek its substitute gratification thru association with a suitable mate presenting in his or her person the fetishes of the loved parent or brother or sister.
The individual whose fixation is purely neurotic should be freed of it by analysis and allowed to seek a mate without being inhibited by ghosts.
A human being has met another human being of the opposite sex and is attracted to him or her by the conscious or unconscious memories which his or her physical and mental make up brings back. An organic compulsion drives a man to seek a certain woman who is to be his sexual mate. We say then that the man is in love. What is the tangible, observable, measurable meaning of the condition of being in love?
