Alex Rosenberg’s Guide to Reality and morality under scientism

Alex Rosenberg’s An Atheist’s Guide to Reality is the most radically scientistic book that I’ve read. I should thus like it a lot! And generally I do, but with some reservations.

I’ll address here one argument that Rosenberg makes about morality and politics which I think is faulty, and, indeed, not “scientistic” enough. I’ve seen other atheists make the same argument so it is worth exploring. Continue reading


Fundamental ontology: what is the universe actually made of?

In his classic “Feynman lectures on physics”, Richard Feynman starts by saying:

If, in some cataclysm, all of scientific knowledge were to be destroyed, and only one sentence passed on to the next generation of creatures, what statement would contain the most information in the fewest words? I believe it is the atomic hypothesis that all things are made of atoms — little particles that move around in perpetual motion, attracting each other when they are a little distance apart, but repelling upon being squeezed into one another.

Of course atoms are not the basic unit, they are composed of nuclei surrounded by electrons. The nuclei are then composed of protons and neutrons (and short-lived virtual particles such as pions), and the protons and neutrons are themselves composed of quarks and gluons.

But what is the ultimate level? What, when one goes down to the most fundamental level, are things made of? While there are lots of opinions there is no accepted answer, and mulling it over for myself I realised that none of the options are attractive in the sense of aligning with intuition about what “physical stuff” would be made of. Here are some of the possibilities: Continue reading

Trinity Lutheran Church vs Comer and the free exercise of religion

I have a confession to make. Reading the US Supreme Court’s ruling on Trinity Lutheran Church vs Comer, I am more persuaded by the majority decision written by Chief Justice Roberts than by Justice Sotomayor’s dissent. In this I differ from many secular campaign groups who deplore the ruling and are worried about what it might lead to.

In brief, Missouri runs a program using old tyres to improve children’s playgrounds. Trinity Lutheran Church asked to benefit from this. Their bid was rejected because it came from a church, in line with Missouri’s rule that no taxpayers’ money can go to a church. The Supreme Court ruled 7–2 that rejecting the bid simply because it came from a church violated the constitutional ban on laws “… prohibiting the free exercise” of religion. Sotomayor’s dissent, in contrast, focused on the other half of that clause, banning laws “respecting an establishment of religion”.

The two phrases together are commonly interpreted as erecting Jefferson’s “wall of separation” between churches and the government, preventing taxpayers money from going to churches and preventing the government from taxing churches. Continue reading

Tim Farron’s resignation does not reveal secular intolerance

British Christians have been writing to the newspapers complaining that the resignation of Tim Farron as leader of the Liberal Democrats shows that liberal secularism has revealed itself to be intolerant. “We are kidding ourselves if we think we yet live in a tolerant, liberal society”, said Farron himself. The resignation “should make us wary of those who pretend to be tolerant and liberal” (Telegraph), “… is evidence of wider intolerance in British society” (Christian Institute) and “… symbolises the decay of liberalism” (New Statesman), opine others.

When Christians are unhappy it is usually because they are waking up to the fact that society is increasingly unwilling to grant them the special privileges to which they are accustomed, and to which they think they are entitled. The special privilege being asked for here is not that they be allowed to advance their beliefs in the public arena. That is accepted and not under threat by any secularist or Western atheist, however much Christians try to pretend otherwise. Rather, the special privilege being asked for is to advance such views and to have them exempted from critical scrutiny. Continue reading

The CARM rejection of subjective morality

I’ve been pointed by a reader to a critique of the idea that morality is subjective written by the Christian Apologetics & Research Ministry. CARM is the website of Matt Slick, a conservative Christian who believes in the infallibility and literal intent of the Bible, and thus, for example, in the literal existence of Adam and Eve.


What struck me about Slick’s arguments against morality being subjective is that he doesn’t really address whether it is true that morality is subjective, he discusses whether he wants it to be the case that morality is subjective. He then sort of assumes that what he wants to be the case must then be the case. Continue reading

The Second Law of Thermodynamics made easy

The Second Law of Thermodynamics is one of the few scientific laws that has attained a status in wider culture, even featuring in rock tracks by Muse. Famously, C.P. Snow cited an understanding of the 2nd Law as something that every educated person should have.

The 2nd Law is often stated in technical language that makes its meaning hard to understand, but the basic principles are actually readily grasped. I was recently challenged to explain the 2nd Law at the level of a bright 13-year-old, and so here is my attempt. Continue reading

Can we please distinguish between speech and actions?

The distinction between speech and action matters. Shouting fire in a crowded theatre endangers people’s safety and so is not just speech but also an “action” that can rightfully be outlawed. In contrast, showing contempt by burning the US flag or a copy of the Quran is “speech” and so should not be outlawed. The act of burning an item of your own property is lawful, and the added contemptuous attitude amounts to speech. This is highlighted by the fact that the method of disposal of old flags recommended by the US military is … burning them, though respectfully. Likewise some Islamic authorities recommend burning as the method of disposal of old copies of the Quran that are no longer fit for reading.

Those in favour of free speech generally hold that any speech that stops short of incitement to violence, or otherwise putting people in direct physical danger, should be lawful and accepted. Those against free speech think otherwise. But they don’t want to admit to being against free speech; few people do. So they label those in favour of free speech as “free speech absolutists”, and begin their arguments with: “I am fully in favour of free speech, but …”. From there they muddy the water by trying to negate the distinction between speech and action. Continue reading
