Metaphor of Floating Foundations

Ocean beneath:
W1 reality is like a raging sea, a chaotic and unknown reality.
Foundation L2:
L2 is where our sensations and direct observations with the help of common sense gives birth to science. It creates an incomplete, evolving, and ever-changing model of W1 reality. Even L2 is floating on the ocean of unknown.
First And Second Floor L1 and L3:
L1 is where we fill out the incomplete W1 model with our hypotheses and guessworks (metaphysical beliefs). L3 is where our W1 hardware, memory of past emotions, and ... construct over L2 (instincts, and preferences).
In a healthy construction (that serves the feeler the best), L2 is the most robust, and then L1 and L3 are built on top of the foundation of L2.
Any construction is an interpretation of the ocean of unknown. Understanding this is frightening for any sane person. When even L2 is an approximate and incomplete description of W1, it's obvious that how much of L1 and L3 are made of illusions. Nezman understands the gravity of unknown. He constructs a well-balanced castle of thoughts on firm L2 foundations and well-proportionate L1 and L3 layers.
