This is a philosophical insight into what is considered one of the properties of a system - memory. In a technical sense, a system is said to be dynamic or to possess memory if its present output depends not only on the present input but also on past inputs. So, basically everything that has happened to the system in the past has left the system changed. So, suppose my computer here were to become old and malfunctional, it would be because it had memory - because it "remembers". We ourselves grow older because every experience we have had has left us changed. We have been modified. We are not our old selfs anymore. For the better or for the worse, we have changed.

In the above discourse, it is to be noted that memory refers to memory as in an absolute physical sense and not any cognitive process.

Not one of my better ideas… Well…
