Mackie, Design, And E.T.

What would it mean if we found alien life? Let’s plunge into the Deeper Waters and find out.

I am going through atheist J.L. Mackie’s The Miracle of Theism now and really, not finding his arguments persuasive. I recently read the chapter on design. Generally, I don’t really use design arguments, at least not as understood today. By the way, if you say the oldest version of design goes back to Hume, I consider that a problem. Sadly, Mackie does say that early on.

One objection often raised is that of alien life and the supposed lack thereof in the universe. I know there are plenty of people who think there are aliens out there, but at this point, the scientific community has no certain evidence of it. As far as we know, most of the universe is uninhabited.

So on p. 141, Mackie points out that if there are countless planetary systems out there and there is life on only one, ours, it is not a surprise that we are here to observe that. The idea can be that if there is one planet that has life, then of course, that there is life on that planet is not a shock. If you deal out enough cards in poker, do not be surprised when eventually someone gets a royal flush.

The idea often given with this and could be what Mackie has in mind as well is that if there was a designer of the universe, surely life would be more common.

If God designed the universe, there would be life everywhere.
Life is not everywhere.
Therefore, God did not design the universe.

Of course, the problematic part of this syllogism is the first premise. That is the one that needs to be backed. That could be a fascinating blog to do sometime, but for now, I wish to instead comment on another point.

On p. 144, he goes to Paley’s watch argument. As an aside here, not all design arguments are meant to be like Paley’s. Ancient and medieval philosophers used design arguments, but it was not about the internal make-up of something so much as about order in the universe, a claim I find much more fascinating.

To get back to the argument of Mackie, he says that if we found a watch somewhere, we would likely think it is designed. However, if we found watches on the seashore at the same rate we found seashells of if we went on dry land and found them at the same rate we find insects, it would not be as impressive. An abundance of watches would work against design.

If there are an abundance of watches, it is less likely that there is design.
There are an abundance of watches.
Therefore, it is less likely that they are designed.

Yet look at these two arguments together.

If there is a lack of life then that counts against design.

If there is an abundance of watches, that counts against design.

Now yes, one is about watches and one is about life, but the principle is the same behind them both and this is the problem. I do acknowledge C.S. Lewis pointed this out years ago, but it struck me as an example of today. If however the evidence comes out, it is an argument against design, then it becomes “Heads I win, tails you lose.”

If you are wanting my opinion, I am not making either argument nor am I arguing against any argument. What I am arguing against is the idea that whatever way the wind blows, it will support your claim. I also freely accept many Christians can do this as well with our own claims. We need to watch ourselves too.

And finally, the best design arguments are the older ones, but they are much older than Hume.
