This is rather more anecdotal than I’d hoped, often exploring memories through Fernyhough’s relationship with his own memories: memories of his father, teaching his children about his father, comparing his memories of a place to re-experiencing the place later on, etc, etc. Some of this is fascinating — especially his interviews with his grandmother, recording all the stories she had to tell. It’s a very personal thing, not scientific, but it’s interesting all the same; I sometimes get the same urge with my grandmother, just to capture the weird things she says sometimes that she trots out like proverbs and yet no one has ever heard before!
There are some discussions of more scientific stuff, and most of it seemed perfectly solid from what I know from other authors; it’s just, under the sea of anecdotal data, I don’t feel like I learned much. There’s nothing wrong with the writing style or the content, but it’s more H is for Hawk than scientific.
