  Dennis Hackethal revised idea #2082.

Deutsch says our body of knowledge keeps growing both deeper—better explanations—and wider—new fields, more facts, rules of thumb. He thinks depth is winning. It might be interesting to asses what that balance looks like in 2025.

Consequently (they say), whether or not it was ever possible for one person to understand everything that was understood at the time, it is certainly not possible now, and it is becoming less and less possible as our knowledge grows.

Chapter 1

If something already isn’t possible, how could it become less possible?
Isn’t possibility a binary thing? As opposed to difficulty, which exists in degrees.

Perhaps it’s premature, but I’d love to discuss:

  1. why DD thinks the four strands already amount to a theory of everything

  2. why DD presents quantum mechanisms as having already subsumed general relativity

  3. what other (proto)strands we could envision and why they are indeed a meaningful addition to the 4 strands

How do you think of "problems" for genes?

  Erik Orrje commented on idea #2010.

Do explanations have to be expressible?

#2010·Dirk Meulenbelt, 2 months ago

Can't think of how it could be otherwise. Do you have any examples of inexplicit explanations?

  Dennis Hackethal revised criticism #2012.

The important thing is to be able to make predictions about images on the astronomers’ photographic plates, frequencies of spectral lines, and so on, and it simply doesn’t matter whether we ascribe these predictions to the physical effects of gravitational fields on the motion of planets and photons [as in pre-Einsteinian physics] or to a curvature of space and time.

Steven Weinberg, Graviation and Cosmology (p. 147), John Wiley, 1972. As quoted in chapter 1.

I’m getting conflicting results online for this quote. Some sources that quote the same passage say singular ‘effect’, others use the plural like Deutsch does.

I don’t have access to the original text, so I can’t say for sure if this is possibly a slight misquote or if different people are just quoting different editions.
