The Theory of Deletion

"Delete".
Amazing button it is.
What's more amazing is that, mostly, it comes with an undo option.

But we also delete time, moments, people, happenings, images, places, objects, facts, prayers, dreams and pains from our lives. Mostly, it's not in our control. And definitely, it does not come with the undo option. And whenever, by some stroke of chance, some deletion is undone, it again is not in our control.

Let's take people. They constitute the first part of the theory. We delete names, retain faces. We delete faces, retain names. Sometimes we retain both names and faces, but delete the connection between them. For the people, whose name and face we retain in connection, we often delete most of the things they said or did to us, and vice the versa, but retain an opinion, a sensation towards them. And as time passes, we fail to find evidences in support of our opinion about that person. This process is, fortunately and surprisingly, does not have a true inverse. That is, the amount and type of retention and deletion between two people is not mutual.

The "mutual" part of the theory holds only in case of people. And also in case of men and dogs, and other pets, or non-pet animals in some intersting cases. In short, it holds true in case both the source and the destination of deletion have biological memory units... that is, the mind.

The second part of the theory deals with places and objects and such things which are tangible to people's lives. The destination of the memory, that is, the tangible entities, do not have memory. They exist in the memories of others, and are shared to different extents by different people. And there is no upper or lower limit on the total amount of memory that a tangible entity enjoys in the share of minds of all the people who came in contact with it. So, everyone is free to remember the entity to whatever extent his mind permits.

There's another aspect of deletion (or retention) which covers intangibles, like thoughts, opinions, wishes, dreams and fears. So to say, things that are mostly personal to a mind, borne out of the course of individual's development and experiences with the world. Some of these entities are shared by more than one individual, though the source is the main, and the auxiliary individuals' memory is not a concern as long as the source's memory is retained... unless its a wish of a wife (source), but forgotten by the husband(auxiliary)... which creates a chain of events which are mostly retained by both the parties... and it then becomes a case of the first part of the theory.
Anyways, coming back to the third part, it's potentially the most powerful among the three, and can affect the other two to a great extent. The perception of the individual may cause retention of seemingly true entities or incidences, which may not always be true completely. Strong wishes may change memory patterns over time, thereby manipulating the reality inside the source's mind, mostly without his/her concious awareness of the manipulation happening in there. Pain, is a very strong cause of deletion. Oxytocin, biologically, is a burning example of that.

The three chaptered theory of deletion, probably will be challenged more often than accepted. I respect all those who want to theorise their concepts about deletion and retention. This is just the way I had to put, and of course, I myself am prone to "perception" and "wishes" and "auxiliary individuals" that influence the course of my life, and so is my theory.
