The teleological argument for God is based on the idea that the natural order of things in the universe points to a Designer that stands outside of it (the Greek telos means roughly 'end' or 'purpose'). Of the many arguments for God's existence, this one has gotten a bit of a bad rap lately.
Usually associated with guys like William Paley--you may recall his (in)famous 'watchmaker' analogy--the general conception among educated folk these days is that since Darwin, there is no need for such outdated ideas about design.
I beg to differ.
In fact, it seems that the more we learn about our universe--particularly its beginning--the more obviously and readily the inference to design presents itself.
Without further ado, the argument:
(1) The fine-tuning of the universe is either due to physical necessity, chance, or design.
(2) It is not due to physical necessity or chance.
(3) The fine-tuning of the universe is due to design.
And of course if design, then a designer.
In the next post, we'll examine the two premises in more detail, but here I want to get clear on what is meant by 'fine-tuning.' *
If you express the laws of nature mathematically, they contain what are called 'constants.' Basically, these are values that are not themselves determined by the laws; they just are the values they are. For example, in Einstein's famous E = mc2, the constant 'c' is the speed of light.
Well it turns out that in order for the universe to permit life at all (much less life at the advanced scale we see), the values of the various cosmological constants must fall within an extraordinarily small range of possible values. Further, there are quite a few of these constants, and they all have to obtain independently, or else no life. This means that in order to calculate the probability of our universe developing complex life, we have to take the already ridiculously unlikely odds of each constant and then multiply them.
These odds are really impossible to illustrate accurately, so I won't even try. Just picture as many blue marbles as there are atoms in the universe and one red one. Now imagine the odds of you picking out the one red marble while blindfolded. If you can picture this, then you still aren't really even close to the kind of odds we're talking about with the constants. Not close at all.
And yet, there they are. And here we are to talk about it. Next time, we'll consider the options that have been offered to explain this other than design.
