Transference [wikipedia] is considered one of the most important and interesting events in psychology.
Sometimes it is defined very narrowly to refer to something that occurs between a "patient" and a "doctor". Specifically, the substitution of the analyst for a parent of the "patient". A patient sees their parent in the doctor. But it can be used in a broad sense to understand many things.
One (online) definition of the transference is "In psychoanalysis, the process by which emotions associated with one person, such as a parent, unconsciously shift to another, especially to the analyst" or "the redirection of attitudes and emotions towards a substitute, such as towards the analyst during therapy".
Carl Jung's The Psychology of the Transference is a detailed look at some alchemical texts from centuries ago, with an eye to observing steps that the human mind tries to follow by whatever means, including through Transference.
Although there are many mechanisms and techniques each person uses to develop psychologically, the Transference stands out because it lets a person deduce, or extrapolate, many things.
Transference would seem to fall in the category of 'deception' or 'lie'. If you perceive, for example, an analyst to be your parent, or even to represent your parent, then there would seem to be some self deception. But looking deeper, you might speculate that the parent represented something, and you would have to ask 'was that deception?' or 'did I give my parent authority that was not theirs?'.
The answer to that riddle might be that there is a pure 'parent' function in the mind, but very few people represent that function adequately. In other words many parents leave their children with a conflict between a) their (the child's) relationship with parent and b) another variable. The other variable? It has to be one of two things. Either a construct of society (an unnatural group creation built by necessity), Or a natural ideal.
To summarize, a person is raised by a parent (i.e., their parents). If the energy the child has toward the parent leads to conflict in society, eventually a Transference will be forced. The purpose of the Transference will always be to bring the individual "to nature".
