A Guide to Reality, Part 2

A couple days ago, I stated my intention (you might even say I promised) to work through Alex Rosenberg’s The Atheist’s Guide to Reality: Enjoying Life Without IIlusions right here at WOCS. That was in part 1. Believe it or not, this is part 2.

In his preface, Professor Rosenberg explains that he wrote the book for people who are ready to face reality. By that he means people who believe there is no God (atheists) or have serious doubts (agnostics) and who want to know what science has to say about a few perennial questions that keep some of us awake at night. He thinks the scientific view of reality has certain consequences:

The book is about those consequences. It provides an uncompromising, hard-boiled, no-nonsense, unsentimental view of the nature of reality, the purpose of things, the meaning of life, the trajectory of human history, morality and mortality, the will, the mind and the self (ix).

Rosenberg scoffs at attempts to reconcile science and religion. He holds that “an unblinking scientific worldview requires atheism” (viii), which explains why most of America’s leading scientists are atheists and those who aren’t atheists are mostly agnostics.

I don’t think it makes any difference to Rosenberg whether science leads us to atheism or atheism leads us to science. He started out in physics, ended up in philosophy, branched out to biology and economics, and somewhere along the way became an atheist. But someone might proceed in the other direction: doubting God’s existence and then looking to science to explain why the world is the way it is. His contention is that science and atheism are compatible, while science and religion (or theism) aren’t.

In my opinion, however, he exaggerates the conflict. You don’t have to deny God’s existence in order to be an excellent scientist. Instead, what you need to do is put thoughts of God aside when you’re doing science. Science is the search for natural explanations, not supernatural ones. Invoking God as the explanation for the existence of the human eye, for example, amounts to throwing up your hands and choosing a different subject. If you want to speculate about some god or other creating the universe and initializing the fundamental constants (like the mass of an electron) to values supportive of life, you’re not doing science. In this methodological sense, a scientist has to be an atheist.

But despite what Rosenberg says, nobody knows why or how the universe came into existence; or if it’s always existed in some form or other; or whether our universe is one of many. Even if scientists eventually figure out the answers to those questions, we’ll never be able to rule out the possibility that some creator or creative force beyond our universe got the cosmic ball rolling. Nor will we ever be able to prove that God, Zeus or Santa Claus isn’t watching right now to see if we’ve been naughty or nice. What evidence could there be to prove that kind of negative?

What we can say is that, historically speaking, science has shown a vast number of previously mysterious phenomena to be natural processes. There is no reason to think we need an entity outside space and time to explain why there are stars and galaxies, or why there are birds and bees, or why the Red Sox sold Babe Ruth. As fewer phenomena have seemed to require a supernatural explanation, it has seemed less and less likely that there is Anyone Up There. As we’ve learned more about our world, ancient stories have become much less plausible. So far as science is concerned, God is a dead letter.

But that doesn’t necessarily mean God is dead, however implausible that he, she, it or they either are or ever were “alive”.

Next time: stories and scientism.

A Guide to Reality, Part 1

Alex Rosenberg is the R. Taylor Cole Professor of Philosophy and chairman of the philosophy department at Duke University. He’s published more than 100 articles and reviews. Among his books are Microeconomic Laws: A Philosophical Analysis, Hume and the Problem of Causation, The Structure of Biological Science and Darwinian ReductionismLike most philosophers these days, he writes for an academic audience. In 2011, however, he published a book for a general audience: The Atheist’s Guide to Reality: Enjoying Life Without Illusions.

The title is a little misleading, since Rosenberg derives his atheism from a more fundamental belief called “scientism”. That’s the view according to which, in Rosenberg’s words, “the methods of science are the only reliable ways to secure knowledge of anything”. Unfortunately, there is no word for a person who accepts scientism other than “scientist” and you can be a scientist without believing in scientism. For that matter, you can be an atheist without believing in scientism. 

On the other hand, if you’re sure of God’s existence, The Atheist’s Guide to Reality probably won’t change your mind. It’s a book for people who are willing to take science extremely seriously, even to the point of concluding that many of humanity’s most common beliefs are wrong. Since I’m one of those people, I enjoyed the book, even while disagreeing with some of Rosenberg’s conclusions.

Because The Atheist’s Guide is well-written and covers so much ground (for example, physics, evolution, perception, consciousness, free will, history and morality), I thought it would be an interesting exercise to work through it, explaining and responding to Professor Rosenberg’s views right here on this blog (while continuing to write about other things, like class warfare and mowing the lawn). 

If you want to consider the professor’s views first-hand and be able to correct my account of what he has to say (assuming you want to participate), the paperback and electronic versions are going for less than $15 online.

Next time:  the relationship between science and atheism.

Cosmic Justice

According to the Detroit News, a 19-year old black woman, Renisha McBride, had a car accident in the predominantly white suburb of Dearborn Heights, Michigan, at around 2:30 a.m. on Saturday morning. Her cell phone battery was dead, so she began looking for help. After knocking on the door or ringing the bell at a house on Outer Drive, she was shot in the head and killed. The Dearborn Heights police department found her body on the front porch. They know who killed her but haven’t released the person’s name.

Michigan is one of the states that now has a “Stand Your Ground” law. Michigan’s law says that a person has the right to use deadly force against another person if he or she “reasonably” believes such force is necessary to protect himself, herself or someone else from imminent death, great bodily harm or sexual assault. Given the facts reported so far, asking the woman ringing your door bell at 2:30 a.m. what she wanted or calling 911 would have been more reasonable than putting a bullet through her head. The incident is now in the hands of the Wayne County prosecutor.

In news that could be related, physicists have discovered that the Higgs field, what the New York Times calls “an invisible ocean of energy that permeates space, confers mass on elementary particles and gives elementary forces their distinct features and strengths” might undergo a phase transition resulting from a random quantum-level fluctuation. This phase transition would make the Higgs field much denser than it is now. That change would destroy everything in the universe more complex than hydrogen, the simplest element there is. 

In fact, a random fluctuation of this kind might have already occurred, meaning that the resulting phase transition (in effect, a wave of destruction traveling at the speed of light) might be heading for us right now. We won’t know if it’s coming or notice if it arrives: “the idea is that the Higgs field could someday twitch and drop to a lower energy state, like water freezing into ice, thereby obliterating the workings of reality as we know it”.

It would be as if Someone finally got fed up and turned off the cosmic switch that controls everything around us, including Dearborn Heights, Michigan.

Fortunately or unfortunately, depending on your view of cosmic justice, it is very, very unlikely that the Higgs field will change any time soon. Nevertheless, it could happen, especially if Someone gets really fed up.

Update:  Apparently, it was a man who killed Renisha McBride. He did it with a shotgun and says it was an accident. He also says he thought she was an intruder (the kind who knocks on the front door or rings the bell?).

Reason, Prejudice, Passion, Pessimism

Giacomo Leopardi (1798-1837) was a great Italian poet. He was also one of Western civilization’s great pessimists. Below is an 1821 extract from his Zibaldone di pensieri (“Commonplace Book of Thoughts”):

The power of nature and the weakness of reason. I’ve said elsewhere that for opinions to have a real influence on people, they must take the form of passions…. One could quote endless examples to demonstrate this point. But since all opinions that aren’t, or don’t seem to be, prejudices will have only pure reason to support them, in the ordinary way of things they are completely powerless to influence people.

Religious folks (even today, and maybe more these days than ever before, in reaction to the opposition they meet) are more passionate about their religion than their other passions (to which religion is hostile); they sincerely hate people who are not religious (though they pretend not to) and would make any sacrifice to see their system triumph (actually they already do this, mortifying inclinations that are natural and contrary to religion), and they feel intense anger whenever religion is humbled or contested.

Non-religious people, on the other hand, so long as their not being religious is simply the result of a cool-headed conviction, or of doubt, don’t hate religious people and wouldn’t make sacrifices for their unbelief, etc., etc. So it is that hatred over matters of opinion is never reciprocal, except in those cases where for both sides the opinion is a prejudice, or takes that form.

There’s no war then between prejudice and reason, but only between prejudice and prejudice, or rather, only prejudice has the will to fight, not reason. The wars, hostilities and hatreds over opinions, so frequent in ancient times, right up to the present day, in fact, wars both public and private, between parties, sects, schools, orders, nations, individuals—wars which naturally made people determined enemies of anyone who held an opinion different from their own—only happened because pure reason never found any place in their opinions, they were all just prejudices, or took that form, and hence were really passions.

Poor philosophy then, that people talk so much about and place so much trust in these days. She can be sure no-one will fight for her, though her enemies will fight her with ever greater determination; and the less philosophy influences the world and reality, the greater her progress will be, I mean the more she purifies herself and distances herself from prejudice and passion. So never hope anything from philosophy or the reasonableness of this century.

About 100 years later, William Butler Yeats (1865-1939) expressed a similar thought in The Second Coming:

Turning and turning in the widening gyre
The falcon cannot hear the falconer;
Things fall apart; the centre cannot hold;
Mere anarchy is loosed upon the world,
The blood-dimmed tide is loosed, and everywhere
The ceremony of innocence is drowned;
The best lack all conviction, while the worst
Are full of passionate intensity.

In the 21st century, nobody believes in pure reason anymore. The question now is whether the more reasonable have enough passion to counteract the less reasonable. Leopardi would have been doubtful.

Note: the Leopardi quote is from a New York Review of Books blog post that is much less interesting: http://www.nybooks.com/blogs/nyrblog/2013/oct/17/headline-headaches/

The Great Agnostic: Robert Ingersoll and American Freethought by Susan Jacoby

According to The Great Agnostic, there were two great opponents of religion and proponents of naturalism in American history: Thomas Paine and Robert Ingersoll. Strangely, hardly anyone today has heard of Ingersoll. (For that matter, few Americans today know that Tom Paine had anything to say about religion.)

Robert Ingersoll was a world-famous lawyer and lecturer who lived from 1833 to 1899. He was considered perhaps the greatest orator of his day. He had an extremely successful career traveling all across the country, lecturing to large, appreciative crowds, among whom were many ordinary, religious Americans. He was a member of the social and political establishment, but his public statements opposing religion insured that he never held political office.

In Susan Jacoby’s words, Ingersoll “explained the true meaning and value of science … in a more understandable fashion than any scientist, even the brilliant popularizer Thomas Henry Huxley … Second, Ingersoll made the connection between repressive religion and everyday burdens and injustices as no one had before him.” 

Among the targets of Ingersoll’s scorn were slavery, capital punishment, the subjugation of women, debtor’s prisons, the mistreatment of animal and Social Darwinism. He believed that “there were no social injustices in which religion did not play a major role” — for example, in the belief that the existence of the poor was God’s will, and the idea that men should exert authority over women. 

Jacoby suggests that Ingersoll’s primary purpose was to remind his countrymen that the United States was founded by men who rejected the idea of theocracy: “the glory of the founding generation was that it did not establish a Christian nation”. Ingersoll rejected all supernatural explanations for human behavior and the world around us, while hoping that science and reason would eventually lead us to a world of peace, justice and prosperity. Quoting him: “Man through his intelligence must protect himself. He gets no help from any other world…. Let the ghosts go. We will worship them no more”.

Ingersoll came to be known as the “Great Agnostic”, even though he saw no significant difference between agnosticism and atheism. It isn’t clear why his fame diminished over the years. Although his collected works comprise 12 volumes, perhaps his written words weren’t as powerful as his oratory. Maybe if he had written a good summary of his views, he would be as famous today as Thomas Paine is for writing “The Age of Reason” (which, unfortunately, isn’t very famous at all).

One of the virtues of The Great Agnostic is how it shows that our current cultural battles over religion are hardly new. The 19th century featured the same kinds of conflict, on topics like evolution, birth control and government support for religious education. We haven’t made as much progress as we should have. If there had been someone with Ingersoll’s convictions and abilities speaking out during the 20th century, and now in the 21st, we might be a better country today.
