The Edge of the Object Corresponds to the Euclidean Line

The main information system of lives is the genetic information system. The remarkable feature of genetic code is the serial alignment. That is, it has a 1D structure. Furthermore, two major information systems, the language and the computer code, are also isomorphic to DNA. Presumably, human beings might have a tendency to make a similar information system to DNA.
Next, all of these three systems are digital information systems. The important advantage of digital information is that the element of digital information can be the direct target of natural selection (1). DNA consists of four kinds of bases: A (adenine), T (thymine), G (guanine), C (cytosine). Bases are lined sequentially. Each base of DNA can be the direct target of natural selection.
Similarly, the element of the language also determines life and death of human beings. For an example, a phoneme can be critical for the survival of a human. We assume a platoon advancing in a battlefield in the night. In this situation, the distinction between r and l is vitally important. When a soldier found the enemy on the right side, he said “right.” If another soldier hears light instead of right and then he put the light, he will be shot. In such a case, the distinction between r and l determines life and death.
Meanwhile, Plato assumed the ideal one. So, Plato’s one is insensible and has three properties: invariability, indivisibility and equality (2). The natural number is the set of Plato’s one. Furthermore, the ideal digital information corresponds to the natural number. If we can use the ideal digital information for communication, our communication will be completely correct because Plato’s one is equal to each other. However, the complete equality does not exist in the real world (3).
Instead, Plato’s one exists only in the human brain. Necessarily, digital information must be close to the natural number as much as possible. We shall consider the phoneme. Firstly, the phoneme of the spoken language was converted into the letter of the alphabet. Next, print technology was developed. Furthermore, technology has progressed rapidly after the Renaissance.
Now, the text is converted into the text file on the computer. It consists of 0 and 1. That is, human beings have been trying to transform phonemes into signals close to the natural number during the history because Plato’s one is the base of all cognition of all living organisms.
However, our brain created the number, which cannot be represented by natural numbers. Perhaps, our basic cognition system, which consists of sets of Plato’s one, may be insufficient for the cognition of the moving object. Our visual cognition system was developed in order to compensate this fault.
We shall consider this problem. Firstly, There are two kinds of image formats in the computer: the raster image and the vector image. Thea raster image consists of pixels, which corresponds to the natural number. In contrast, the vector image does not consist of pixels.
The basic element of the vector image is the Euclidean line, which corresponds to the equation. The scaling of a vector image is free. It is very important for pursuing a moving object because the size of the moving object’s image changes with respect to the distance from the sensor. Thus, our brain chosen the vector image.
Figure 1. The projection of a cuboid to a plane.
Figure 1 shows the idealized schema of the projection of a cuboid to a plane. To simplify, we shall binarize the reaction of the sensor. The edge of the 3D object corresponds to the boundary of the shadow. The extraction of the edge from the retinal raster image is the main task of the first step of our vision. The edge is extracted in the primary visual cortex (4).
Why the extraction of the edge is important? When we pursue a fast moving object, we must identify it quickly. In order to save the amount of the calculation, our brain must identify the shape of its 2D shadow. Then, we can directly identify it from the 2D image.
Figure 2. The expanded schema of the borderline.
Figure 2 shows the expanded schema of the borderline between the light area and the dark area. As a result of the binarization, a pixel must belong to the light side or the dark side. That is, the borderline between pixels is the borderline between light and dark. This borderline is just the Euclidean line. According to Definition 2 in Book 1 of Euclid’s Elements, a line is breadthless length.
Figure 3. The Euclidean Line.
Figure 3 shows the Euclidean line. This concept binds the figure to Plato’s one. Furthermore, the simple cells in the primary visual cortex extract the Euclidean line, which corresponds to the edge of the 3D object (4). A simple cell in the cat’s primary visual cortex responds to the line of the special direction.
Next, we shall consider the coordinate system of our vision. Because our eyes and our head can move, our viewpoint is always moving. That is, the coordinate system of our vision is not fixed. Hence, our brain can extract the edge of various directions. Figure 4 shows the extraction of Euclidean lines from edges.

The Ancient Greeks elaborated the edge in our brain, and then they created the Euclidean line, which has only length and no width. It is the basic element of the Euclidean geometry. Because it has length, they thought that shapes and numbers were integrated. Though Pythagoras discovered the irrational number, Euclid defined the real number by Definition 5 in Book 5 of Euclid’s Elements. This definition is equivalent to the Dedekind cut. However, this definition is indirect.
Why the Ancient Greeks could not be directly defined the irrational number? Basically, we can output only digital information. That is, our nervous system can output only muscle movement. Its minimum unit is the motor unit, which is indivisible. So, any muscle movement is digital. Even, the experienced craftsmanship is essentially digital. Furthermore, our main outputs are language and DNA, they are digital information. That is, we cannot directly transfer our subjective experiences to other persons.
More generally, the basic information system of life is digital. So, bacteria can transmit almost only digital information. Where does the Euiclidean space come from? Euclidean space was constructed by the Ancient Greeks based on both digital information and the qualia. According to Wikipedia, qualia is a term used in philosophy to individual instances of subjective, conscious experience. We cannot transmit the sense of red itself. We can only say that I see the red color because the human can transmit only digital information.
Figure 5. We recognize the real world through digital information.
Figure 5 shows the relationship among the real world, digital information, qualia and the Euclidean space. We cannot directly recognize the real world. We recognize the real world only through digital information. Thus, we cannot directly access the real world. That is, we can only conjecture the real world.
Next, the Euclidean line is the borderline between pixels. However, there is nothing between adjacent two pixels. Hence, the Euclidean line is created by our brain. Furthermore, we cannot output itself. These features are identical to the qualia.
The Ancient Greeks elaborated the qualia of the edge, and then they constructed the Euclidean geometry. Because they embedded the non-existent line in Euclidean geometry, many problems arose. If any Euclidean line can exist, the size of the pixel of the Euclidean plane must be zero. That is, Euclidean plane does not consist of pixels.
However, even if we use any writing tool, we can draw only a line, which consists of pixels. Hence, we cannot draw any Euclidean figure. This difficulty means that any Euclidean figure cannot be constructed. That is, the world, which we can handle, is only the digital world.
However, this fact does not mean that the real world is the digital world. Rather, only digital information may not enough to recognize the true world. Our ancestors would get qualia in order to compensate the shortage of the digital information. Furhthermore, the Ancinet Greeks created the Euclidean geometry based on the qualia of the edge.
