The part of the human brain that stores and retrieves long-term memories, of the concious sensory experience kind, is known as the
hippocampus. The hippocampus is part of a wider linked network of brain regions called the
limbic system, which is responsible for our emotions.
Both the process of sensory input and the storage and recollection of memory data (by the rational thinking prefrontal cortex) has zero chance of going through untainted by emotional subjectivism because it is done by our emotional brain centre. Our memories were chosen according to how we were feeling, not what we were thinking, and on retreival must pass again through the region which is responsible for how we feel.
That's why thought that is of any use requires
thinking and probably research, some number crunching and comparison to shared experience. Personal recollection of experience of the "I was there" kind, even if that is an appeal to an authority as august as oneself, is never untainted with emotion.
Good piece of writing - I know because I read it!
