GTR0: the continuous forward and reverse pass between description and organism

2. 1. The GTR0 Diagram

[ INSERT FIGURE: GTR0 diagram ]

The GTR0 cycle — four spaces SEED, Cells, Organs, Organism and the three transitions between them; the arrow at the back is the reverse pass RTR0, returning the organism to the description.

The diagram shows four cubes: SEED, Cells, Organs, Organism. Each cube is a separate space with its own ontology of objects. The three transitions between them are marked by three operations: convolution, splice, and chain. The arrow that wraps around all four cubes from behind shows the reverse pass — the return from Organism to SEED. It is precisely the closedness of this path that makes what is depicted life, and not merely a process of growth.

2. 2. The Forward and Reverse Pass

Before examining the spaces one by one, the main point must be stated: GTR0 is not a one-way path. It is a complete transformation that has two directions running inseparably.

The forward pass is unfolding (RTR): the description unfolds into the organism. The compact plan of SEED turns into a working cell, cells assemble into tissues, tissues into a whole organism. The folded becomes the unfolded.

The reverse pass is convolution (DTR): the organism is folded back into the description. The hereditary material is packed into a compact core, ready for transmission. The unfolded returns to the folded.

The most important point, and the one most easily missed: these two passes do not follow one another as two phases. They proceed simultaneously and continuously. The organism does not for a single moment cease to unfold its description — cells constantly read the plan and build themselves according to it; and it does not for a single moment cease to fold itself back — constantly maintaining and renewing the hereditary core. The halting of either pass is death.

This corresponds directly to the definition from the first chapter: life is a continuous, simultaneous forward and reverse transformation. Not a description unfolded once, nor an organism folded up at the end for the sake of offspring, but both processes running together for the whole time that life lasts. GTR0 is the first and most ancient embodiment of this device.

2. 3. Why Exactly Four Spaces

The structure of GTR0 is not chosen arbitrarily. It is forced: each of the four spaces is necessary, and none can be skipped without destroying life.

A description must exist. Without a compact, transmissible plan an organism could not reproduce. Each time, life would arise anew from scratch — and that contradicts the heredity we observe. Hence a space is needed in which the organism exists in folded form, as a blueprint.

A working unit must exist. A blueprint by itself is dead. To live, the description must be unfolded into something that acts — into a unit that consumes resources, responds to its environment, sustains itself. In biology such a unit is the cell.

These two spaces suffice for the simplest life. But as soon as cells begin to combine, a need for two further levels arises — and it arises not by chance, but because the combining of cells passes through two qualitatively different stages.

2. 4. The Four Spaces

a) SEED — the description

SEED contains a compact description of the organism: what is to be built and how. This space is static — the description does not act on its own, it merely stores the plan. The description is remarkably compact: a small volume of information specifies a structure that, when unfolded, consists of trillions of elements.

The biological example is the DNA sequence in a germ cell.

The familiar analogy is a building’s blueprint or a program’s source code: by itself it does nothing, yet it contains everything needed to build a working thing.

b) Cells — the working cells

Cells contains living cells as active processes. Each cell has a membrane, an internal metabolism, the ability to receive and send signals. The nature of the objects here is fundamentally different from that in SEED: the description has neither processes nor time; the cell has no static blueprint — it has continuous activity.

The biological example is a bacterium, an amoeba, a single neuron. The familiar analogy is a running program: the program’s text has turned into a working process that is doing something right now.

c) Organs — functional structures

Organs contains groups of cells united by a common function. The ontology is the same — these are still cells. What is new is that the cells now occupy definite positions relative to one another and are linked by direct contacts. Cells of the same type gather together and form a tissue capable of doing what a single cell cannot.

The biological example is muscle tissue, a nerve ganglion, a gland. The familiar analogy is several identical programs working jointly on a common task: individually each is limited, together they form a working node.

d) Organism — the integral organism

Organism contains organs linked into a single whole. The ontology is again the same — cells. But now different organs are arranged into a system of dependencies: one sustains the work of another. The heart supplies the muscles, the muscles move the body, the nerves control the heart. An organism is not a set of organs but their connected chain, where the whole is not reducible to the sum of its parts.

The biological example is an animal, a plant, a human. The familiar analogy is a system of distinct interacting services: each performs its own role, but they work only together, passing results to one another.

2. 5. The Three Transitions

Between the four spaces lie three transitions. It is important to distinguish the terms: the operation of the level as a whole is a transformation (GTR0); the three operations within it are transitions. A transition exchanges one space for another within the level; a transformation binds the level into a closed cycle.

a) Convolution: SEED and Cells

The first transition is between the description and the working cell. It is the sharpest of the three: the very nature of the object changes. On one side is a static blueprint, on the other a living process. There is no smooth intermediate between them: one cannot be “half blueprint, half cell.” Such a transition, with a complete change of nature, Gativus calls convolution.

In the direction of unfolding, the description unfolds into a cell — in biology this is the reading of genes and the construction of the cell from them. In the direction of convolution, the working cell folds back into the description — the packing of hereditary material for transmission to offspring. Both directions, as said, proceed continuously.

b) Splice: Cells and Organs

The second transition is between individual cells and a tissue. Here the nature of the object does not change: before and after, these are cells. Something else changes — the cells acquire mutual arrangement and connections. A new dimension is added to the space: where a cell is located and with whom it is connected. Such a transition — an extension without a change of nature — Gativus calls a splice.

In biology this transition is known by its own name — histogenesis, the formation of tissues:

identical cells differentiate and assemble into functional tissues. Its reverse side is the separation of a single cell from the organism for reproduction.

c) Chain: Organs and Organism

The third transition is between individual organs and the whole organism. The nature of the object is once again the same. But now it is not cells of the same type that are connected, but different organs, and they are connected into a system of dependencies: a chain is built up in which the work of one link sustains the work of the next. Such a transition — the superposition of a sequence over ready-made units — Gativus calls a chain.

In biology this transition is organogenesis:

the formation of organs and their integration into the systems of a whole organism. Its reverse side is the decomposition of the organism into its constituents at death.

It is worth emphasizing: histogenesis and organogenesis are not an invention of Gativus. They are long-described stages of embryonic development. Gativus only shows that behind them stand two different operations — a splice and a chain — and that both work on one and the same material, cells, without changing its nature.

2. 6. The Closed Cycle and Evolution

The three transitions in the direction of unfolding form the forward pass: SEED, Cells, Organs, Organism. But by itself it is only the development of a single individual. It becomes life because it is inseparable from the reverse pass: the organism continuously reproduces and maintains its description, and this return goes on the whole time, not once at the end.

The culmination of the reverse pass is the transmission of the description to offspring. And here the key word is new. The return is not to the same description but to a slightly altered one. This return-with-alteration is precisely the mechanism of biological evolution. Most alterations are neutral or harmful, and such lineages die out. But sometimes an alteration gives the organism a capacity that raises survival — and then the new description spreads. In the Gativus architecture evolution is not added to life from outside as a separate mechanism: it is built into the cycle itself as the inexactness of the return.

Thus a single structure — a closed cycle of four spaces with a continuous forward and reverse pass — encompasses all of biological life: the development of an individual from embryo to adult organism, inheritance from generation to generation, and the evolution of the species over time. These are not three different phenomena but three manifestations of one cycle.

2. 7. Incomplete Forms of Life

Not all organisms pass through the full cycle across all four spaces. And this does not make them less alive — their cycle is simply shorter.

Single-celled organisms — bacteria, amoebae, yeasts — pass only through convolution: the description unfolds into a cell, the cell divides and passes the description on. They have no need of splice or chain. The cycle is closed at the level of a single cell, and this is full-fledged life.

Intermediate forms — colonies, biofilms, slime molds — pass through convolution and a partial splice: cells combine, but without a full division of functions and without a stable system of organs. These forms show how multicellularity took shape in evolution — step by step, one transition at a time.

Multicellular organisms — plants, animals, fungi — pass through the full cycle across all four spaces.

2. 8. GTR0 as Foundation

GTR0 is the only wholly material level of life. Everything else — perception, behavior, thought, will — is built on top of it and will be examined in the following chapters. But all of this superstructure is realized not by new matter but by the specialization of already existing cells: the nervous tissue that makes perception and thought possible consists of ordinary cells belonging to Organism.

Hence the central thesis of the whole book. Nature did not invent a separate mechanism for each successive level of life. It took the ready, well-tuned device of GTR0 — the compact model of an organism with its continuous forward and reverse pass — and realized it anew on new material. Perception, thought, and will are arranged isomorphically to biological development: the same transformation of four spaces and three transitions, the same continuous cycle of convolution and unfolding — but not over cells, over information.

Therefore, to build the full architecture of life, there is no need to invent something new on each floor. It suffices to understand the device of GTR0 — and to trace how one and the same transformation rises from level to level, acquiring specific properties while preserving its original structure. It is this ascent that the following chapters are concerned with.
