Semiotic Constraints of the Biological Organization 219THE EXTERNAL WORLD AS A SEMIOSPHERE
To exist, the world should be semiotically closed by including potentially its observer.
The physical spacetime appears in this world as a subset of the semiotic set of interconnected
Umwelts common to all observers. Each functional component of an Umwelt has a meaning
and so represents the organism‘s model of the world. An organism creates its own Umwelt
when it interacts with the world and reshapes it. Consequently, the Umwelts of different
organisms differ, which follows from the individuality and uniqueness of the history of every
single organism. When two or more Umwelts interact, this creates a semiosphere (Lotman,
1990) in which organisms exhibit goal-oriented or intentional behaviors. Semiosphere is a set
of all interconnected Umwelts arising from their interaction.
Following this logic of interconnected Umwelts, we can approach a simple and non-
contradictory explanation of the anthropic principle: the creation of a sign in the semiosphere
corresponds to the conditions of observability of the world because signs themselves are
formed on the basis of the principle of observability. This ―bootstrapping‖ formulation of the
anthropic principle substantiates physical constants as the only solutions for fixed points in
the branching history of observations (quantum measurements). Solutions for the physical
constants potentially can be of any value, but only those that are realized are consistent with
the condition of observability. The objective reality of the spacetime appears as
corresponding to the basic ideal principles of construction of the physical world. From
branching patterns of the quantum wave function, the world appears in a way that it is
appropriate for life and consciousness. All other possible worlds remain potential and cannot
be actualized.
The spatiotemporal relations between objects of the physical universe are governed by
limits of computation (Igamberdiev, 2007, 2009). The relational spacetime, being
semiotically constrained and having a semiotic value, is a robust fitness landscape for all
observers. The supposition that all observers are equivalent generates objective spacetime
patterns of the general theory of relativity (Igamberdiev, 2008). However, the equivalence of
all observers is an approximation and, in reality, the spacetime patterns imposed by them
acquire relative equivalence via some kind of a fitting process. This process becomes more
uniform with the appearance of living systems based on similar reflective and functional
cycles that can interact with a relative predictability. Living systems, being active players in
the world and having different clocks, interact, thus generating the perpetually evolving
fitness landscape.
The presented analysis of objectivity in the physical, the biological, and the psychological
worlds shows that objective patterns are formed in the relational universe as necessary
conditions for the operation of reflective loops. These loops arising independently have
common values uniting them in the branching history of actualizations. The objectivity of the
truth of reason in logic and mathematics, in semiotic loops substantiates the objectivity of the
truth of fact of the physical world, in other words, the actual physical objectivity has its origin
in the ideal objectivity of ultimate logical structures of the world. These structures are
actualized via unique sets of physical parameters making the world observable and
intelligible. The reality can be described as a set of self-maintained semiotic systems
exhibiting themselves externally (on macroscales) and interacting via perpetual process of
signification (reducing the microscale), which introduces universal computable laws
