Two points relating to my last post regarding the principles that ought to govern ‘freethought blogs’.
Was I talking about FTB?
Freethought blogger Kylie Sturgess of Token Skeptic comments:
From the comments here and elsewhere, it’s very clear everyone reads this as about Freethought blogs. Vagueness isn’t much help and detracts from your overall message, I think.
Kylie is right; I had FTB in mind while writing the piece, and I do think that, in general, FTB would benefit from my advice (although I don’t think her blog has any of the problems I mentioned).
Here’s why I did not make my article about the network ‘Freethought Blogs’. Firstly, I think that the principles I outlined should apply to any blog that considers itself a ‘freethought’ blog, and not just those on the FTB network. Secondly, I don’t think that the problematic blogs are all on FTB. Thirdly, if I was to make the claim that FTB doesn’t follow what I called the Principle of Rational Discussion (PRD), then commenters may justly expect evidence for that claim. This was a tricky one for me. I could provide one or two instances, or show vast amounts (and there really are vast amounts) of evidence. The former might not convince people that there was a widespread problem, and the latter would be very long and time-consuming.
I therefore preferred the constructive approach, thinking about how bloggers interested in promoting freethought might wish to police their blogs. If someone wishes to see the dirt on FTB (and the other blogs I had in mind), then the evidence has been documented all over the place. My advice would be to go there and look. Look at a contentious issue (especially involving social justice), and watch what happens when someone posts a reasonable disagreement. Better still, disagree yourself and see what happens. Follow the PRD, and see if they follow suit.
Dealing with disagreement
Anyway, here’s one example that dissent is treated less than favourably by one of the FTB leaders. Today PZ Myers posted a YouTube video about former FTBer thunderf00t‘s dismissal from the network. I commented:
I don’t recall thunderf00t saying anywhere that he didn’t support the idea of gender equality. I read him as disagreeing about the idea of extra harassment policies at conferences. You may disagree with him on that point (I do), but his position is quite compatible with a belief in gender equality.
I thought that was reasonable enough. Anyway, I tried to respond to another comment a few minutes later and I had been blocked from commenting by the channel owner, PZ Myers. The comment above was my only comment. Worse still, I notice commenters who say things like:
PZ IS ruining the image of atheism dude. He’s allowing the stupid dogmatic ultra feminist viewpoint to take over and divide us.
…have not been banned, and are still arguing hours later. It seems clear to me that PZ allows commenters who make the ‘other side’ look bad, and bans those who argue calmly and reasonably. This creates the illusion that one side is calm and rational (his side) and the other side is ranting and raving, and I say that is dishonest of him to do so.

Edit: For clarification: I am not necessarily talking about the network Freethought Blogs (FTB). I am talking about any blog that wishes to promote freethought.
Edit: Kylie Sturgess of FTB posted a response to me at http://freethoughtblogs.com/tokenskeptic/2012/07/08/on-advice-for-a-freethought-blog-by-notung. She raises good points relating to FTB as a network.
Advice for a ‘Freethought Blog’
What is ‘freethought’, and why might we want to be a ‘freethinker’? Freethought is a reason-based approach to forming beliefs about the world, and a respect for scientific inquiry. It is productive; when we employ reason when assessing claims, or test hypotheses using the scientific method we tend to get useful results. There are other reasons for preferring the freethinking approach but for my purposes I need not worry about them here.
The opposite of freethought is dogma. We want to oppose dogma for a variety of reasons, of which I will just provide two (from Mill’s On Liberty). Firstly we are fallible beings, and if we do not allow our beliefs to be challenged we can never really be sure that they are the correct ones. Secondly, even if the belief happens to be true, granting it the status of dogma avoids a ‘collision with error’ (as Mill puts it). This collision allows us to see the weak points in our position in order to refine it appropriately. It encourages us to learn how to defend our position, and develop a stronger understanding of why what we believe is true.
So what would a ‘freethought blog’ look like? If it is to warrant the name, it would surely practise and promote the approach outlined above, putting reason before all else. It does not matter necessarily what conclusions one is led to by this approach, but rather that the posts one writes attempt to shake off received wisdom and dogma, and endeavour to replace it with a freethinking methodology. A freethought blog would encourage rational discourse in the comments, where arguments are challenged robustly and reasonably, and all opinions live or die by the quality of the reasoning that leads to them.
So I propose what I will call the Principle of Rational Discourse, which will take two forms; one weak, one strong.
The Weak Principle (wPRD):
Stick to the arguments and remain civil.
If we do not stick to the arguments but instead prefer to attack opponents personally, we distract the conversation with irrelevancies. Furthermore, if you or your opponent get needlessly riled up, then emotion takes the place of reason and the quality of the arguments diminishes. There is no good reason not to be civil. If the arguments are poor, then the surest way of demonstrating this is with a reasoned rebuttal, rather than with invective. If they are ‘trolling’, i.e. posting comments of little substance merely to anger people, then they may be justly blocked from commenting in order to prevent the discussion from breaking down and suffering a catastrophic loss of productivity.
The Strong Principle (sPRD):
Concentrate your arguments against the strongest objections to your view.
I call this a ‘strong’ principle since rather than simply granting dissent negative liberty, it involves treating dissent as a positive good. Those who hold a genuine desire to discover the truth always seek out the strongest objections to their position. We must (if we are to obey this principle) be sure to present our opponent’s arguments in their most favourable light, and employ what is known as the ‘principle of charity’. Why should we do this? Suppose somebody makes an argument that you find prima facie ridiculous. Now consider two possibilities: the first is that we have misunderstood their case and end up unintentionally weakening their argument, and the second is that we understood their argument perfectly, but they are a poor reasoner and so their claims are easy to refute. In the former case, we have misrepresented our opponent’s argument and made it easier for us to knock down (this is known as a ‘straw man fallacy’). In the latter case, all we may achieve is that we ‘win’ the argument, and what good does that do? Would it not be preferable to see whether your beliefs withstand a more robust challenge? Thinking in this way can be a learning experience, even if your beliefs remain standing at the end. We gain more of an understanding of our views by examining them in great detail; holding them up to the light to reveal any imperfections, no matter how small. It seems then that the best way to deal with such a situation is to find the interpretation that provides you with the strongest challenge. I would go so far as to say we should help our opponent out – show them how their argument can be improved. As well as being a nice gesture, it demonstrates the sort of intellectual honesty essential for freethought.
My Suggestion
I propose that a ‘freethought blog’ ought to employ wPRD at the very least. However, it seems to me that a blog that is engaged in a disinterested search for the truth should also employ sPRD. We want to be proven wrong. One of my friends at CERN once said that he hoped that they never found the Higgs Boson, since the idea that their current understanding of particle physics was mistaken was a much more exciting prospect than obtaining data that simply confirmed what they already knew. Being wrong is a chance to learn something new about about ourselves, about each other, about the world. We should embrace that – for freethinkers, nothing is sacred.
Some Examples
Name-calling, threats, insults, sarcasm, invective and speculations as to the agenda of a commenter all violate wPRD.
If you are a prominent skeptic leader who recounts an experience and makes a particular moral claim, and then a well-known colleague takes issue with that claim in a way you dislike, try to understand what they mean and what they are arguing. Interpret their argument so that it is as strong as possible (sPRD). Note the points of agreement and the points of disagreement. Ask for clarification if you are not sure. Any examination of their personal characteristics is a waste of time at best (and an ad hominem fallacy at worst), and would violate wPRD. Outline precisely and efficiently why you do not find their objection sound, and await their response to your arguments. That way, a productive discussion might get going, and you may end up convincing many more people than otherwise.
If you are blogging about an issue you are genuinely concerned about, and a skeptic leader raises the idea that the way the issue is being framed might actually be contributing to that issue, then you have two main choices; a rational discussion, or an attack on the skeptic leader. In the former case, the common ground will be more apparent, the differences can be worked out as best as is possible and there is a much greater chance that the issue gets solved to everybody’s satisfaction. In the latter case, you may actually stifle the discussion, and the issue is much more likely to linger and cause more harm that it would have otherwise. It is clear that those who are serious about the issue and not simply seeking drama should prefer the former option.
In Closing
My advice is intended to be constructive. Comments are welcome and appreciated. Disagreement is encouraged. Please keep all comments civil.

The kalam cosmological argument for the existence of God is the centrepiece argument for apologists such as William Lane Craig. Its power is found in the simplicity of its validity, and in the intuitive plausibility of its premises.
Take Craig’s formulation:
P1: Whatever begins to exist had a cause
P2: The universe began to exist
C: Therefore the universe had a cause
It may only show that the universe was caused by something, but this fact goes a long way towards identifying the God of classical theism (Craig employs a few giant leaps to reach a personal God, but they are outside the scope of this discussion for now). I am always surprised when atheists are ready to concede the conclusion. To allow that the universe had a cause is to admit that which we do not know. After all, it should worry us that we are answering a question regarding the genesis of our universe simply from a logically valid syllogism. It is a synthetic proposition, and Craig requests that we assent to its truth without leaving our armchair.
I will attempt to show, contrary to appearance that this argument is in fact logically invalid if analysed properly. Take the apparent form of the argument:
P1: Everything B is C
P2: u is B
C: u is C
This apparent form is of course logically valid. So what happens if we analyse the premises? Take P1. We either know this is true from experience or by intuition. If experience, we run into many problems.
Firstly, when do we experience something coming into existence, as opposed to the rearrangement of pre-existing matter? When a house is built, we might say that it ‘comes into existence’, but it is clear that we do not mean it in the same sense as we do when we speak of the universe ‘coming into existence’. The house is created from bricks positioned and cemented, and the high-level name ‘house’ is given to the result of this change. Even with personal identity, we ‘come into existence’ at conception (or soon afterwards) but, short of committing to dualism there is nothing created ex nihilo, in the way that we mean when we speak of the beginning of the universe. It is therefore problematic to appeal to our experience when speaking of things ‘coming into existence’.
Secondly, if we speak from experience we must have had a wide and comprehensive enough experience to allow our inductive conclusions to have a sound basis. Even ignoring the previous problems, if we experience things only coming into existence as a result of a cause, these things are necessarily part of a universe, and we may never encounter the birth of a universe. We would have to lay claim to experience informing us ‘whatever begins to exist, even a universe, has a cause’, which we cannot. If we choose to leave out ‘even a universe’, the later conclusion can no longer follow.
The strongest justification for P1 therefore, is intuition. It is inconceivable that, out of nothing something may be created without a cause. Hume answered this by noting that both cause and effect can be conceived independently, and there is no necessary connection between them. This goes some way, but we still may wish to say that accepting the truth of P1 is more rational than holding it false. This is a plausible view, and thus we turn to P2.
Craig employs an argument from the impossibility of an actual infinity of events to support P2. This premise is very unlikely to be denied by an atheist, as it is in line with modern cosmological science. The Big Bang theory, crudely put, postulates both space and time created out of nothing, and so there is little to say about P2 other than that it is true. However it may be said that the sort of beginning that we speak about when we talk of creation ex nihilo is a very different sort of beginning than that which we are familiar with.
Let us work with a reasonable definition of ‘beginning’:
D1: Something ‘had a beginning’ if and only if there was a time t1 at which it did not exist and a time t2 at which it did exist, where t1 temporally precedes t2.
I propose that this definition is intuitively what we mean when we speak of ‘beginning to exist’. Space and time created out of nothing, however does not satisfy this definition. Instead, we might use:
D2: Something ‘had a beginning’ if and only if there was a time t2 at which it did exist, such that there is no time t1 at which it did exist, where t1 temporally precedes t2.
The definitions are distinct; D1 entails D2, but D2 does not entail D1. It seems to me that when we intuit a beginning, the definition we use is D1, as it is the time at which the thing does not exist that forms the clear idea of ‘coming into existence’ that we require. Therefore it is unreasonable to accept only D2 as the definition of ‘beginning’ in P1; we must use D1. Conversely, in P2 we must use D2 as D1 is false in this context. Given that the definitions are not interchangeable, the meanings of the word ‘beginning’ in each premise are different.
Therefore, the syllogism is formally invalid:
P1: Everything B1 is C
P2: u is B2
C: u is C
If this seems incredible, consider an analogous argument:
P1: All Greeks are humans
P2: The Parthenon is Greek
C: Therefore, the Parthenon is human
Here, the word ‘Greek’ is used twice but with different meanings. For an argument in this form to be logically valid the first predicate must be identical to the predicate ascribed to the subject in the second premise.
I propose that this is the mistake in the kalam argument; a false equivocation between two distinct conceptions of ‘beginning to exist’. If the universe had a cause of its existence, we are not in a position to know it, and must instead hope that our empirical understanding of the creation of new universes grows, if indeed our own is not the only universe in existence and if it is not beyond our capacity for scientific inquiry.

Why AV is Better than FPTP
On the 5th of May, we have an opportunity to change the way we vote for MPs. We should prefer the better system – even if AV is not perfect per se, if it is better than FPTP we should vote YES and if it is not, we should vote NO. For a democracy to function properly, it requires a voting system that is disinterested, universal, simple to understand and most accurately conveys the wishes of the voters.
Which System Will Most Hurt the BNP?
I must get this common concern out of the way from the outset. It is self-evident that if a system is biased towards a particular political party or view then it is not as democratic as a system that is not. Our argument should make no claims about the actual results of the voting system – i.e. if one system is likely to result in Party A getting in, unless the system was in some way rigged in favour of Party A then it cannot be objected to on those grounds. We might as well reject democracy completely if we want to argue in that way, and posit a static government controlled by our favourite representatives.
For this reason, both the YES and NO campaigns are wrong to argue that their system will hinder such parties as the BNP. It is irrelevant to the debate to make predictions about possible outcomes, and seriously unprincipled to try to design a system around our most revered and reviled politicians.
The Universality of Democracy
We are all wise enough now to know that a democratic society ought to give everybody the vote, regardless of race, gender, religion and so on. It is also clear that the options must not be limited, i.e. it should not be the case that we can vote for Parties A and B but not C, if C has a candidate in that constituency. It would discriminate against voters who preferred C, and would not be truly universal.
This brings me to the first problem with the status quo. There are certain candidates such that, if we were to vote for them, we would be ‘throwing our vote away’. This is a phrase that is far from uncommon and yet, if we really are throwing the vote away by voting for certain candidates then we really should not vote for them. We should vote for the party that stands a chance to win, either A or B but not C, for then we would be wasting our vote. This is a lot like the case I outlined above, only this time it is not a systemic mandate but rather an effect of that system.
Under AV, if I prefer Party C I can vote for Party C without worrying about the effect of my vote since, if the unthinkable happens and Party C lose, I can still have an effect on the final outcome. The NO campaign claims that this would mean the end of ‘one person, one vote’. The opposite is true. Under FPTP, once the party you voted for is eliminated, your vote is also eliminated. From that point on when, say Labour and Conservative candidates are battling it out, you literally have no say in the outcome. Under AV, even though the vote moves around, it is only in one place at any given time. It is only allocated to your second choice once it is eliminated with your first choice. Therefore, AV abides by ‘one person, one significant vote’ whereby FPTP has ‘one person, one possibly wasted vote’.
The NO Campaign’s Response:
“Your vote isn’t ‘wasted’ if your preferred candidate didn’t win – it still gets counted in the same way as everyone else’s. There are winners and losers in every election, and that wouldn’t change under AV. In a seat where the MP wins with 51% of votes under AV, for example, 49% of votes would still be ‘wasted’ by the Yes campaign’s definition.”
[From http://www.no2av.org/why-vote-no/av-myth-busting/ ]
This response misunderstands the point. It is not claimed that if you lose, the vote is wasted. Rather, if you vote for a certain party, the vote is wasted. The NO response fails to address this.
The Simplicity of AV
Under FPTP, if the majority (50%+) vote for Party A, Party A wins. Under AV, if the majority vote for Party A (50%+) , Party A wins. Under FPTP, if all parties fail to win a majority, we have a hung parliament. It would be quite easy to make a NO2AV-style advertisement in which somebody tries very badly to explain this to a classroom of perplexed kids, who muse afterwards about how they cannot understand why the ‘winning’ party with 40% of the vote did not just assume power. However, I prefer arguing my case with actual arguments, which I’m sure will be seen as a deeply subversive tactic.
Under AV, if and only if no party wins a majority, the party with the least votes is eliminated and the lost votes are allocated to the voters’ second choices. This process is repeated until there is a majority.
That’s how simple it is. I never want to hear anybody say that it is complex ever again. I overheard a lady on the train saying (to paraphrase) “the current system is complex enough as it is – most people don’t know how to put an X in the box! Imagine if they had to put numbers in the boxes!” Aside from the egregious disrespect for her fellow citizens, if anybody did struggle with the process of ranking candidates in order of preference, they would be perfectly welcome to only select one candidate. Problem solved.
“I Crossed the Line First, and Yet I Did Not Win!”
What is the purpose of voting in a democracy? Is it analogous to a sporting event, such as a horse race? To start with, the rules of a horse race are clear. Cross the line first without disqualification, and you win. Democracy is not a competition. We are not rewarding people for good work, or for crossing any line. We are selecting candidates who best represent the wishes of the voters.
To look at how it does this, I will look at a hypothetical case. It does not matter whether this reflects the current situation or not. If a voting system is fair, it should work across all possible situations. We should not tailor a system to the current political climate.
Suppose a country with three political parties. The North Party, the South Party and the Far South Party. Let us suppose that 40% of voters have south-leaning views, and that half of those voters consider themselves far-south. The remaining 60% are north-leaning, and half of those are far-north.
The votes are cast. The results are: North Party 60%, South Party 20%, Far-South Party 20%.
The North Party assumes power under both FPTP and AV.
Now let’s consider what would happen if, instead 40% of the voters were North-leaning and 60% were South-leaning.
The votes are cast. The results are: North Party 40%, South Party 31%, Far-South Party 29%.
FPTP: North Party wins, even though most voters are South-leaning. Far-South voters wasted their vote, and they should have voted for the South Party, even though they really wanted the Far-South Party.
AV: Far-South voters tended to vote for South Party as second choice, due to their similarities. Those votes pull the South Party up to 60%, and they rightly win the election. In this situation, a North Party government would have only represented a minority. They may have ‘won’ in the sporting sense, but democracy is too important to be treated like a little competition.
In Closing
Please consider which system produces results that most accurately reflect what the voters want. Do not think about the effect it may have on your favourite candidate, but consider a principled look at what democracy is really about. I invite you to share my view that AV is the superior system and, given that fact, we should vote YES in the referendum on 5th May.

Craig asserts that the physical constants in the universe are “finely-tuned” “for” human life. He is right in saying that if the physical constants were different then the universe would also be different, and hence human life wouldn’t exist.
We could say that any set of laws, X produce a result Y. If you change X then you cannot help but change Y. Whatever version of Y you look at, you will always find a corresponding “finely-tuned” set of laws X. Therefore whatever universe one looks at, the laws are finely-tuned to produce it.
Craig however states that the laws are “designed” for human life. I can only think of two ways of knowing this. The first is if we know that God created the universe for human life. We cannot accept this as Craig’s reason, as it would beg the question of the debate. The second way we could know if the universe was designed for the emergence of human life is if we knew human life is what was being “aimed” for. Now I don’t know how Craig could prove this to us, but simply saying that our set of laws X give rise to a universe containing human life Y is not enough.
To illustrate this, imagine dealing five cards at random. What was the chance that your particular hand was dealt? Pretty low! This would only be significant if you knew you were aiming in advance for that particular result.
Furthermore, our fundamental constants are not really perfect for human life. If evolution were re-run, would humans evolve again? We would expect similar organisms with eyes (the eye evolved five times independently), but there would not necessarily be humans. If the physical constants were different (or, incomprehensibly, different laws entirely!) we still might get “life” of another kind, perhaps even unimaginable to us. Even if we did not get any life, there may be possible universes that contain things that are far greater, beyond our wildest speculations.
So, in conclusion, for Craig to rescue his argument he would have to show that the “purpose” of the universe was to produce humans, and that there are no possible universes that contain anything more desirable than human beings. I don’t see how anyone could prove such a thing, and Craig’s argument fails.
