The ‘inside’ of the ‘outside’. Basic Building Blocks

Starting point are the preceding thoughts about a minimal scenario for a common action of people.

In that scenario we meet each other as humans with our bodies, which we experience as part of a ‘body world’.

The rich manifestations of these human bodies linked to the subjective experience of each individual point to a corresponding ‘diversity behind the surface’ of the bodies. In everyday life we also like to talk about our ‘inside’, about ‘the inside’ of a human being. But, what is this ‘inside’?

The history of medicine is also a history of the exploration of the ‘inside’ of the body starting from the ‘surface’. This history is complemented by the history of biology, which has expanded the view from the present into more and more of the past, into the ‘origin of species’, into the structure of living things, and at some point it was clear that the smallest units of a ‘biological living being’ are to be found in the ‘biological cells’.[5] This opens up the view of an incomprehensible large space of interacting cells, which makes talking about an ‘inside’ difficult.

FIGURE 1. The fertilized egg cell of a human being multiplies in a self-organized growth process in the form of somatic cells, forming a ‘body’, which are colonized by microbes (bacteria) on the surface as well as inside.[1] An important part of the somatic cells is formed by the brain, which consists of approximately equal parts of neuronal cells and non-neuronal cells.[2]

If one takes the ‘cell’ as the smallest biological unit [3], then one can make a direct connection between a single fertilized human egg cell up to those inconceivable quantities of cells that emerge and organize themselves in the course of a growth process (ultimately over the entire lifetime).(See Fig. 1) To date, this complex process has only been partially researched, and even all the quantitative data are so far still only estimates based on the known factors.

If we compare the number of body cells together with the bacteria in the body (about 137 x 10^12) with the estimated number of stars in the Milky Way [4] then, when we assume 300 billion stars in the Milky Way, we come to the conclusion that the number of cells in a human body together with the internal bacteria is approximately equal to the number of 457 galaxies in the format of the Milky Way. This indicates the huge dimension of only one human body.

Through our cells, which make up our bodies, we as humans are connected to all other living beings. While we each live in a particular present, our cells point back to an incredible history of some 3.5 billion years, during which biological cells have traveled a path that has led from single-cell organisms to increasingly complex cellular structures that have resulted in billions of different life forms throughout history. This history is studied by ‘paleontology’ in conjunction with many other sciences.[6]

So when we talk about the ‘inside’ of a body, we are talking about a ‘galaxy of cells’ which are in a living exchange with each other ‘around the clock’. We ourselves with our ‘consciousness’ do notice almost ‘nothing’ from all this. All this happens ‘without our conscious action’. The ‘sound’ of 457 galaxies of cells with altogether about 127 trillion (10^12) single cells as actors nobody would be able to ‘process’ it consciously.

Knowing this, is it not possible that we can say a little bit more about this ‘biological-galactic inside’ of our body?
