There are really 2 shapes of reality:
The physical world, with its realm of mysterious relations and this weird capacity to be the same for all of us, and the sensory world, which is a really intimate experience extremely difficult to describe (especially if you don’t share much DNA with us Humans).
As we’re not that good to make something objective out of the physical world with our subjective senses, we elaborated Physics; as a way to describe the physical world based on how it act upon itself. Meaning we can only correlate physical events with other physical events; building models made of wavelengths and energies. Things that have no meaning to our sensory world.
From the second one, we elaborated psychology; as a way to describe the sensory world based on other sensing agents. Meaning we try to correlate ideas based on interpreted experiences and derive models. Similarly, it’s the sensory world acting upon itself, but with the extra difficulty of accounting for a variety of opaque sensory worlds. Even if the architecture is genetically similar, we cannot see what’s inside or understand it from the physical world perspective.
And, in-between, as a way to match those really odds worlds, there’s the curious task computation. This domain is a way to match bidirectionally physical events with sensory events; to have the information from the physical bit to an intelligible idea or function, then back to the bit.
Giving this, my point is a question you should ask yourself:
Are we really filling the objective we gave ourselves?
Addendum: this is inspired, but different, than Hayek’s analysis in “The Sensory Order”. In his approach, he talks about “orders” instead of “worlds” used in this article.
Comparatively, in Serf Layer, the “physical world” is “perception” and the “sensory world” is “interpretation”. Which I believe is much more intuitive to expose them functionally. But Hayek wrote this in a much different era where computers were still a post-war secret and the Tractatus Logico-Philosophicus was a recent book.
