Hi George (addressing both the cyclist and the grandfather),
very well written essay, well structured, a pleasure to read!
Now, following your comments in my page: if you wanted to really force me into one of the two branches of the choice:
1. Universe (or multiverse) from randomness within mathematical forms -- intentionality as epiphenomenal, OR
2. Universe from cosmic generative intentionality - humanity as part of a purposeful process,
I would choose option (1), if not for other reasons, for the fact that, in my opinion, it defines a much more attractive research agenda: trying to explain away the magic of goals and intentionality. This can be done so well w.r.t. biology, as mentioned by several essays here. (It is always a pleasure to reveal the trick behind the magic, for example showing that the specific distribution of word lengths in a printed western language does not reflect a 'magic' universal feature of human intelligence, but simply derives from attributing some probability to the blank (word_separating) character.)
At the other side (2) I see a much higher risk to mix a scientific approach with other perfectly respectful... aims and intentions. Some of your passionate passages in support of choice (2) reminded me of the visions by Teilhard de Chardin, in content, style, and tone.
It seems to me, however, that the two choices you describe are just the black and white extremes of an interesting spectrum (I see the narrative benefits of this setting), and I would gladly sit somewhere in the middle. For example, I am absolutely convinced of the important role that emergence, enriched with top-down causation, can offer to the growth of complexity in the universe, and I would not see this feature compatible only with choice (2), but also with choice (1).
In fact, one of the abstract pictures I prefer is that of a deterministic universe, mathematical in the sense of computational, with emergence and top-down causation as possibly the most fundamental drivers of evolution.
I would even accept terms such as 'sacred' (as in S. Kauffman's 'Reinventing the Sacred') in connection with these driving forces, but would stop there. In your essay, on the other hand, I perceive the need to describe a physical universe that naturally supports the most transcendental human aspirations, and that reveals divine intentions behind the scenes. Maybe it's a wrong impression. But if it is wrong, then our views may not be that different.
You write: "I believe this question is, and always will be, from an empirical standpoint, undecidable." Is this not unreasonably pessimistic? How can we exclude that some day, maybe in the near future, some computer experiment will generate an artificial dynamical system evolving according to simple algorithmic rules, yielding an ecology of agents that resemble the biosphere, and that develop forms of cooperative symbiotic, 'altruistic' or moral behaviors, without need for a priori design and goal? How would you feel, in this case? Progress in this direction is under way. Wouldn't this count for you as an empirical way to rule out a grand design and ultimate purpose?
You write: "science is a wonderful and intensely collaborative adaptation that serves to minimize discrepancy between theory and reality and maximize information - effectively exporting entropy to the larger world in the process." Do you have a precise form of exported entropy in mind, for this interesting example?
A rather trivial remark: obviously, the universe does not love us back. This is clear, for example, to all the children that were killed yesterday, in Syria, by chemical weapons.
Finally, in case you'll find yourself revising the text for publication (e.g. in the Springer Frontiers Series), I have two minuscule editorial suggestions (pleasing my taste -- you may well disagree!):
"On at least one planet, Earth, some of those chemicals reacted" --> remove "Earth".
"One species, humans, was able to build civilizations and science." --> remove "humans".
Sorry for the length. Bye!
