I have a pre-pub copy of this book via Amazon Vine. As I set down to read this, I found two things rather quickly I believe will aid a discussion on memory and the Historical Jesus.
The author, Charles Fernyhough, writes,
This view of memories as physical things is guaranteed to mislead. The truth is that autobiographical memories are not possessions that you either have or do not have. They are mental constructions, created in the present moment, according to the demands of the present. (p5 – please note that the pages numbers are likely to change in final print form)
I want to persuade you that when you have a memory, you don’t retrieve something that already exists, fully formed — you create something new. Memory is about the present as much as it is about the past. A memory is made in the moment, and collapses back into its constituent elements as soon as it is no longer required. Remembering happens in the present tense. (p7)
What might this mean? I would propose that without knowing the principles of cognitive memory, the Evangelists could very well have sought to collapse memories. I touch on this in my book, especially in the realm of Pilate/Caesarea-by-the-Sea. This is also the principle behind post-diction, I would suggest.
Anyway, if you are interested… check out the book.
