There is something it is like to be.Thomas Nagel · What Is It Like to Be a Bat? · The Philosophical Review, 1974

The paper the whole consciousness debate still argues with, read on a JSTOR print with pen on all sixteen pages. The margins caught both load-bearing pillars, called the Chalmers lineage twice before checking, and translated Nagel's wildest proposal into a working vehicle he already uses.

The lines he pulled

“The fact that an organism has conscious experience at all means, basically, that there is something it is like to be that organism.”

p.436 · starred: “basic pillar of Nagel's thesis”

“If physicalism is to be defended, the phenomenological features must themselves be given a physical account. But when we examine their subjective character it seems that such a result is impossible.”

p.437 · “second major pillar”

“There are facts that do not consist in the truth of propositions expressible in a human language.”

p.441 · where the margins started supplying examples

“It appears unlikely that we will get closer to the real nature of human experience by leaving behind the particularity of our human point of view.”

p.444 · “here is the turn coming”

“Otherwise we cannot even pose the mind-body problem without sidestepping it.”

p.450 · the last sentence, starred: “land the plane”

The read, page by page

p.435
  1. ASat with the reduction list — water and H2O, gene and DNA — and flagged it “still not sure,” honestly, instead of glossing. The whole paper runs on why those identities worked and the mind-brain one doesn't.
  2. BWe probably do not have access to the box consciousness sits in. — written three pages before Nagel makes that argument himself.
p.436
  1. AChalmers echoes this; cites Nagel later in the work on this topic, already read. — a lineage call made from memory, mid-read. It checks out.
  2. B★ Basic pillar of Nagel's thesis. — “something it is like for the organism.”
p.437
  1. BSecond major pillar, the law the rest hangs on. — subjective character resists a physical account.
  2. ·Bottom of the page: an order to build a bank of classic philosophy terms, a priori onward. — the terms bank opened the same day.
p.440
  1. BMarked the symmetry move: intelligent Martians studying us would be wrong to deny there is something precise it is like to be us. — the access argument arriving in its own clothes.
  2. CWe have to work around this: acquisition plus translation, consensus, definition. — reading Nagel's constructive turn correctly, where casual readers see only a wall.
p.441
  1. AFacts no human scheme could hold: suppose the existence of a creator, or an alien mind, as fact.
  2. BThe analytical flow and precision of AI versus our own. — his example of a mind whose facts may not fit our propositions.
  3. CA point of view is a type, not one person: being homosexual as a fact fully graspable only from inside it. — “perfect defense during pride month lol.”
p.443
  1. CAt the footnote on removing the bat's own viewpoint: beauty is in the eye of the beholder, lol. — species-specific experience, compressed to a proverb.
p.444
  1. AHere is the turn coming. — objectivity that works everywhere else starts moving AWAY from the phenomenon here.
  2. BForm of inquiry meeting purpose of its function. — why experience alone does not fit the reduction pattern.
  3. ·At the Mona Lisa footnote: the same issue as an engine reading a photo album to build a site, a tiny image is not the experience. — Nagel's 1974 footnote, live in this week's build log.
p.445
  1. AThe gist following the turn. — particular viewpoints are not part of the common reality they both apprehend.
  2. BAnd this is where Chalmers' work picks up the mantle. — written at “no presently available conception gives us a clue.” Second lineage call; also correct.
p.446
  1. AThe higher self, read against the non-occurrence case in the imagination method.
p.447
  1. AWe can take a mathematician at his word once the demonstration makes clear a fact exists and could work theoretically. — holding an “is” open without its framework.
  2. BThe individual subjective is what makes it non-reductive.
p.448
  1. ·Worth reading, flagged at the footnote joining the other-minds problem to the mind-body problem. — a future read queued from inside this one.
  2. BThis is step 1; to solve, move to 2. — the paper filed as the opening move of a longer program.
p.449
  1. AObjective phenomenology: basically a rich person vlogging to share with us slash aliens. Should that be the proposal's vehicle? — a description of experience for beings incapable of having it. That IS the assignment.
  2. BYouTube in general as the first-person learning device that triggers pondering in another person. — the joke made serious one margin later.
p.450
  1. AInternal thought as physical phenomena, process. Interesting. — at the footnote where Nagel concedes what an expanded physics would owe.
  2. ★Land the plane. — at the close: without the objective concepts, the mind-body problem cannot even be posed.

“Common terms and consensus on them must be secured before any verdict can occur to explain how the two overlap, differ, interplay.”
