Our Immune System

Aside perhaps from the brain there's no system in the human body as complex as the immune system.

The 10 minute animation below gives an overview of just some aspects of the system, but there's so much complexity involved in our immune responses that it would take more than 10 minutes to cover it all.

The immune system is an astonishing feature of our bodies, one that we largely take for granted and don't think much about until something in it goes awry. It's so amazingly complex and so dependent upon massive inputs of information that to believe it somehow arose through blind mechanistic processes requires a herculean exertion of one's will and a suspension of every ounce of skepticism.

In fact, the case could easily be made that it takes far more credulity, far more blind faith, to believe that the immune system is a fortuitous accident than to believe that it was designed by a mind.

After all, we have abundant experience of minds developing information-rich and complex systems, but we have no experience of such systems being produced by unguided processes and purposeless, goalless forces.

Between two possible competing causes, whichever one is the best explanation of a particular phenomenon is the cause we should accept.

In the case of the immune system the cause of this beautifully organized, highly complex, information-rich system is either a very long sequence of extremely improbable, unguided genetic "accidents," or it's a mind.

Given that all of our experience makes mind the more rational explanation it seems that the only reason anyone could have for choosing unguided, natural processes as the cause of our immune systems is that they've a priori ruled out mind as an explanation, but that's an irrational, question-begging move.

It's like saying that the immune system must be the product of blind natural processes because the alternative, mind, simply cannot be the cause. But how do we know that it can't be the cause?
