Immunity system complexity: T cells identify self, non- self (Introduction)

dhw: Thank you for again repeating my own argument (bolded). Since no proof exists either way, I suggest that one should keep an open mind. I offer hypotheses. You offer rigidly fixed beliefs.

DAVID: Yes, I have rigid beliefs. You are the one floating around with no beliefs.

dhw: That is the driving force behind most of our discussions. I question your rigid beliefs and offer alternatives, especially when your rigid beliefs seem to lack logical coherence.

DAVID: That is your problem as an agnostic. Not everything is totally logical. That is why we theists take some things on faith.

I’m glad you are acknowledging the lack of logic in some of your beliefs, as opposed to your constant insistence, for example, that it is perfectly logical for your God to specially design millions of non-human life forms, lifestyles and natural wonders although his only purpose was to specially design humans. Frankly, I see no reason to take such things on faith when even you acknowledge that there are other, perfectly logical theistic explanations of the history of evolution.

dhw: The passage I have quoted and bolded makes it perfectly clear that as conditions change, plants modify themselves in order to cope with new conditions. [...]

DAVID: Again your discussion avoids the main point. It the plants controlled their own modification, how did they find the necessary giant protein molecule? The only ability seen in cells is the ability to respond to specific stimuli or to produce required proteins in a seemingly intelligent way.

dhw: Maybe it is not “seemingly” intelligent, but results from real intelligence.

DAVID: Perhaps you might consider that God put some of His intelligence into cellular instructions.

But then I would have to ask myself why he would preprogramme or dabble every single action by every single species of plant, animal, insect, bird, fish etc. if his only purpose was to specially design H. sapiens. Your answer on the cosmology thread was: “To get from bacteria to humans required all the 'non-human elements'.” A good example of your belief that “not everything is totally logical” and of your having to resort to faith as your only answer.
