I saw another review say that this book wasn't necessary. But I bought first and asked questions later. Starting with a very timely chapter labelled "consciousness" in some way, I discovered 1 sentence excerpts of Marx arguing again and again with some famous(?) religious sociologist of the past, followed by apparently unrelated excerpts regarding a natural science of man, taken from roughly every 10th page of the same essay. Marx is quoted as saying that a natural science of man would describe his industry, minus the alienation, but without context, why am I reading the excerpts of a Marxian(?) teaching at the London School of Economics?
