"“Estimated Prophet,” words by John Barlow, music by Bob Weir, has always worked a special kind of magic. Barlow captures that whole slightly (or very) deranged or tripped-out Deadhead vibe so well, but the song’s character transcends that little box over time — both over the time the particular rendition might take, and over the time from when we may have first heard it played or performed to the most recent rendition we have heard. That character stands there in my mind’s eye, calling down the thunder, and he seems so sure, so devoted to his vision, that he stands for everyone who was ever caught up in a transforming belief, who gave in to delusions of grandeur, who believed himself the center of the universe — but wait — haven’t we all done that, at least to some degree? It’s human nature to consider oneself the center of the universe. … Barlow calls on plenty of biblical imagery for the lyrics, with the sea parting before the singer, and fire wheels burning in the air, etc. Pretty much your average run-of-the-mill vision for an experienced Deadhead. The interesting thing, for me, is the notion that this character is a prophet. And therein lies a more subtle biblical reference, not at all overt, but hovering in the back of our minds, perhaps, if we have any biblical training. Namely, the notion, expressed by Jesus in three of the four gospels, and therefore likely to be something he really did say, that a prophet has no honor in his own country. … This is one of those songs, and there are quite a number of them in the Dead’s repertoire, in which a not-entirely-sympathetic character is brought to life, and, in the course of being brought to life, is made more sympathetic."
