Dear Vladimir,
I believe I understood your earlier essay on consciousness, but I am somewhat lost on your current essay. You cover much historical development, and my lack of awareness of certain players may account for this.
You speak of "eidos" as "idea of idea" and state as the basic problem "to find one single structure", the source of "unreasonable effectiveness of mathematics".
My essay begins with a brief overview of my Automatic Theory of Physics which is an attempt to develop "A Theory of theories", based on logical structure (NOT and AND) as physically real and as sufficient basis for counters, counting, and arithmetic-logic of natural numbers, from whence, per Kronecker, all else mathematical follows. The differences or 'distance' between measurements can be used to extract 'features' and this leads (through entropy) to a 'best feature vector' as the prototypical Hilbert space vector. Conservation over eigenvalues leads to eigenvalue equations, and this vector is perhaps the single structure best characterizing the math map of the world. I imagine that this maps, in some way, into your ontological vector, but I'm not sure in what way.
Most of my essay is focused on Bell's confusion between two of the eigenvalue equations, and the erroneous conclusion he draws from a mathematically correct analysis of a physically incorrect (oversimplified) assumption.
I invite you to read my essay and comment, and hope that you find some significant connection between our essays.
My best regards,
Edwin Eugene Klingman
