#4The article does not mention widely distributed Toxoplasma gondii, that actually changes the behaviour of hosts in the interests of parasites. Think you like cats? Think again!
The title led me to believe it might be something more like the gondii situation mention.
There is perhaps an association between gondii and schizophrenia. Here is one meta analysis[1]
"The results suggest that individuals with schizophrenia have an increased prevalence of antibodies to T. gondii. This association is consistent with other epidemiological studies as well as with animal studies."

#5If you take the metaphor far enough anything that exists separately from the cosmic background radiation has a means for separating itself from its surroundings for some period of time. This is true for things that are alive as well as things we don't usually assign identity to: a cereal box has a cardboard flap to keep cereal in and bugs out. A star has gravity and gas pressure in equilibrium to keep most of its mass inside a radius.
People who study consciousness (previously pure philosophers like david chalmers, increasingly mathematical physicists like max tegmark) are fascinated by this kind of thing.

#7Cases where the parasite modifies behavior at the highest level (neurology) remain tricky.

Same for cognitive medium (like mathematics, we are able to think in term of mathematical concept to express ourselves better in daily life matter -> we have more freedom), so augmented human seems far future, but tools are augmenting us everywhere. (Augment = expand capability). And the limit of my tools are the limit of my world.
It's also true for other-regarding preference, if you identify someone (your kid) to be yours, you can take a cost for them. Or lovers, they self-interest the joy of each other.

#9Essentially, parasites were inside the body of most human beings over our evolutionary history, up until the last 100 years. The parasites secrete immune-modifying molecules[1]. And because we don't have parasites as often anymore, autoimmune disorders have exploded in prevalence.
The thinking is that, in the same way that human beings and guinea pigs lost the ability to synthesize vitamin C because it was always available, some people lost the ability to regulate their immune system because parasites were just that pervasive. In other words, our ancestors lost genetic machinery that modulated their immune response because the parasites they had provided that service already. So losing those genes had no effect on their fitness.
It's not a widely accepted theory, but it certainly challenges the notion of self in relation to parasites.

Although I think I see the contours of what you're getting at here, I would like some elaboration on these points. This statement is teleological, and if I was a pedant I would point out that the cereal box was designed while a star is what happens 'naturally' in a universe like ours.
However, I am not a pedant ;) so would you care to explain this metaphor and what it is supposed to 'mean' a bit further?
