My Struggles with the Block Universe

Understand

This document is the second installment of three in the Cerro Grande Fire Series.

• Like its predecessor arXiv:quant-ph/0105039, "Notes on a Paulian Idea," it is a collection of letters written to various friends and colleagues, most of whom regularly circuit this archive.
• The unifying theme of all the letters is that each has something to do with the quantum.
• Particularly, the collection chronicles the emergence of Quantum Bayesianism as a robust view of quantum theory, eventually evolving into the still-more-radical "QBism" (with the B standing for no particular designation anymore), as it took its most distinctive turn away from various Copenhagen Interpretations.
