The epigraph to Chapter 2 is by E. O. Wilson: "Sometimes a concept is baffling not because it is profound but because it is wrong." This book baffled me.
The idea of a "deep truth," as Niels Bohr expressed it, is that "its negation is also a deep truth." Life's apparent contradictions can certainly run deep. But when one writes a fact-based book about subjects including evolution, climate change, war, and when a fetus becomes a human being, one cannot simply make contradictory statements and pass them off as deep truth.
Braden acknowledges that the Earth experiences 100,000-year climate cycles within which are nested shorter-term cycles. He then says they are "all about the Earth's location in space: the tilt, wobble, and angle of our planet relative to the sun and the core of the Milky Way." Especially since he qualifies this with "I am definitely not a climate scientist," he doesn't seem to have the credentials to make the oversimplification that climate is "all about" anything in particular.
One argument in particular left me underwhelmed. Quoting an article in the journal CO2 Science as saying that "changes in atmospheric CO2 content never precede changes in air temperature," he concluded that Antarctic ice core data representing cycles over the last 800,000 years on Earth "shows that the CO2 levels actually lag behind the rise in temperature and cannot be the reason for the warming." I am not a climate scientist either, yet easily I can imagine that just because atmospheric CO2 increase was a lagging indicator of warming in pre-industrial times does not mean it cannot be a leading indicator in the industrial era -- that is, given the relatively recent behavior of burning massive amounts of coal and oil as fuel, CO2 today might play a role in climate change that is different from the role it played in the past. This is just speculation on my part, but my ability to raise such a basic question when the author has already claimed an open-and-shut case suggests a fundamental flaw in his argument. This is characteristic of the entire book: logical arguments are made, but they are so sweeping in scope and so loosely screwed at the ends that they are not persuasive at all.
Other times, imprecision is a major obstacle. In discussing Roe v. Wade, the U.S. Supreme Court decision that ruled it to be unconstitutional for states to outlaw abortion, Braden writes, "the ultimate decision was left to the discretion of local governments. Whether or not abortion is legal would still be based largely upon the values and beliefs of the individual communities." This is imprecise enough as to be inaccurate and misleading. While each U.S. state regulates abortion differently, no U.S. state has the authority to outlaw it entirely. That was the whole point of Roe v. Wade. I am certain the author knows this, but in sentences like this it is not communicated well.
The contradictions seemed to me more messy than deep. He writes: "There can be little doubt on the part of anyone with an honest and open mind that the process of evolution, in and of itself, is very real. It is a fact that we see confirmed in the fossil record of species living in the past." A few pages later, he writes, "If species do, in fact, truly evolve with new DNA, rather than adapt over time, it's reasonable to expect that somewhere in the ongoing search that began in 1859, at least one transitional form would be discovered in the fossil record...there is no physical evidence of transitional species to support this assumption of evolution." Well, were transitional species discovered in the fossil record or not, and does this confirm evolution or not?
The author presents as someone who travels and reads a lot and has all the best intentions to inspire people to live thoughtful, peaceful lives. The text is peppered with interesting questions such as "what would it mean to realize that the wars we fight are over someone else's ideas?" The problem is that these questions don't build on each other and don't go anywhere. Unsupported platitudes such as "in our natural state, we are truly wired for peace" or "when we know the truth of the situation, the choices become clear and the decisions obvious" are ultimately not satisfying.
