Part 3 of my review of the book: “The Big Picture: On the Origins of Life, Meaning and the Universe Itself,” by Sean M. Carroll. Part 2 is found here.
Carroll defines naturalism saying it comes down to three things (p.20) and that “the only reliable way of learning about the world is by observing it”. But how can he know that if he is not God. Suppose for a minute that there really is a Creator God and He gave us a revelation in His written Word. But because man cannot, by definition, observe God, since He is a spirit and outside the realm of detectability by science, how can he know that what God has written is not a reliable way of learning about the world? And this is another self-refuting claim: what observation did he make, or even could he make, that reliably showed that observation is the only reliable way of learning?
His form of naturalism – poetic naturalism (after David Hume) – is just standard atheistic naturalism, but he adds that man has responsibility and freedom (p.21).
“The world exists; beauty and goodness are things that we bring to it.”
He means there is nothing intrinsically good or beautiful. He writes that there are
“No causes, whether material, formal, efficient, or final” (p.29).
Extending the idea of Laplace’s Demon, he writes
“Realistically, there never will be and never can be an intelligence vast and knowledgeable enough to predict the future of the universe from its present state.” (p.34)
In the chapter titled “Reasons Why” he says that Leibniz’s Principle of Sufficient Reason is a mistake. That principle states that “For any true fact, there is a reason why it is so, and why something else is not so instead” (p.40). And he points out that
“Hume noted that conceiving of effects without causes might seem unusual, but it does not lead to any inherent contradiction or logical impossibility.” (p.41)
This leads to his belief that the universe needs no reason to be; it simply is.
“… there are facts that don’t have any reasons to explain them”. (p.42)
He implicitly believes a big bang origin for the universe 14 billion years ago, and says that there are some questions for which we may not get answers.
