Biosemiotics is the synthesis of biology and semiotics, and its main purpose is to show that semiosis is a fundamental component of life, i.e., that signs and meaning exist in all living systems. This idea started circulating in the 1960s and was proposed independently from enquires taking place at both ends of the Scala Naturae. At the molecular end it was expressed by Howard Pattee’s analysis of the genetic code, whereas at the human end it took the form of Thomas (...) |

This paper aims to justify the concept of natural intelligence in the biosemiotic context. I will argue that the process of life is (i) a cognitive/semiotic process and (ii) that organisms, from bacteria to animals, are cognitive or semiotic agents. To justify these arguments, the neural-type intelligence represented by the form of reasoning known as anthropic reasoning will be compared and contrasted with types of intelligence explicated by four disciplines of biology – relational biology, evolutionary epistemology, biosemiotics and the systems (...) |

The ability of predicting upcoming events or conditions in advance offers substantial selective advantage to living beings. The most successful systematic tool for fairly reliable prognoses is the use of dynamical causal models in combination with memorised experience. Surprisingly, causality is a fundamental but rather controversially disputed concept. For both models and memory, symbol processing is requisite. Symbols are a necessary and sufficient attribute of life from its very beginning; the process of their evolutionary emergence was discovered by Julian Huxley (...) |

Metaphors involve immense explanatory power and positive impact predominantly in the scientific education and popularization. Still the use of metaphors in science might be a double-edged sword. Introduction of the computer metaphor to many scientific fields in the last century resulted in reductionist approaches, oversimplifications and mechanistic explanations in science as well as in humanities. In this short commentary we developed further the computer metaphor by prof. Noble and the illusions this metaphor led to in genetics, linguistics and consequently DNA (...) |

As interpreted by Pattee, von Neumann’s Theory of Self-Reproducing Automata has proved to be a useful tool for understanding some of the difficulties and paradoxes of molecular biosemiotics. But is its utility limited to molecular systems or is it more generally applicable within biosemiotics? One way of answering that question is to look at the Theory as a model for one particular high-level biosemiotic activity, human language. If the model is not useful for language, then it certainly cannot be generally (...) |

Recalling the title of Yoxen’s classical paper on the influence of Schrödinger’s book, I analyze the role that the work of H. Pattee might have played, if any, in the development of Biosemiotics. I take his 1969 paper “How does a molecule become a message?” (Developmental Biology Supplement) as a first target due to several circumstances that make it especially salient. On the one hand, even if Pattee has obviously developed further his ideas on later papers, the significance of this (...) |

Umerez’s analysis made me aware of the fundamental differences in the culture of physics and molecular biology and the culture of semiotics from which the new field of biosemiotics arose. These cultures also view histories differently. Considering the evolutionary span and the many hierarchical levels of organization that their models must cover, models at different levels will require different observables and different meanings for common words, like symbol, interpretation, and language. These models as well as their histories should be viewed (...) |

Peirce’s sign model is introduced as incompatible with structural semiology in the majority of semiotics textbooks. In this paper, I would like to argue against this general polarization of the semiotic discipline. I focus on compatibilities between Lucien Tesnière’s syntactic theory (verbal valency) and Peirce’s logic of relatives. My main argument is that structural linguistics is not necessarily dyadic, and that Peirce’s sign doctrine is perfectly structural. To define the structural approach in Peirce, I analyze the notions of form (structure) (...) |

In this dialogue, we discuss the contrast between inexorable physical laws and the semiotic freedom of life. We agree that material and symbolic structures require complementary descriptions, as do the many hierarchical levels of their organizations. We try to clarify our concepts of laws, constraints, rules, symbols, memory, interpreters, and semiotic control. We briefly describe our different personal backgrounds that led us to a biosemiotic approach, and we speculate on the future directions of biosemiotics. |

Life has semiotic nature; and as life forms differ in their complexity, functionality, and adaptability, we assume that forms of semiosis also vary accordingly. Here we propose a criterion to distinguish between the primitive kind of semiosis, which we call “protosemiosis” from the advanced kind of semiosis, or “eusemiosis”. In protosemiosis, agents associate signs directly with actions without considering objects, whereas in eusemiosis, agents associate signs with objects and only then possibly with actions. Protosemiosis started from the origin of life, (...) |

Today there are two major theoretical frameworks in biology. One is the ‘chemical paradigm’, the idea that life is an extremely complex form of chemistry. The other is the ‘information paradigm’, the view that life is not just ‘chemistry’ but ‘chemistry-plus-information’. This implies the existence of a fundamental difference between information and chemistry, a conclusion that is strongly supported by the fact that information and information-based-processes like heredity and natural selection simply do not exist in the world of chemistry. Against (...) |

The “histone code” conjecture of gene regulation is our point of departure for analyzing the interplay between the (quasi)digital script in nucleic acids and proteins on the one hand and the body on the other, between the recorded and organic memory. We argue that the cell’s ability to encode its states into strings of “characters” dramatically enhances the capacity of encoding its experience (organic memory). Finally, we present our concept of interaction between the natural (bodily) world, and the transcendental realm (...) |

This paper seeks to understand machine cognition. The nature of machine cognition has been shrouded in incomprehensibility. We have often encountered familiar arguments in cognitive science that human cognition is still faintly understood. This paper will argue that machine cognition is far less understood than even human cognition despite the fact that a lot about computer architecture and computational operations is known. Even if there have been putative claims about the transparency of the notion of machine computations, these claims do (...) |

The article deals with the notion of the genetic code and its metaphorical understanding as a “language”. In the traditional view of the language metaphor of the genetic code, combinations of nucleotides are signs of amino acids. Similarly, words combined from letters represent certain meanings. The language metaphor of the genetic code, 171–200, 2011) assumes that the nucleotides stay in the analogy to letters, triples to words and genes to sentences. We propose an application of mathematical linguistic methods on the (...) |

We discuss the difference between formal and natural languages, and argue that should the language metaphor have any foundation, it’s analogy with natural languages that should be taken into account. We discuss how such operation like reading, writing, sign, interpretation, etc., can be applied in the realm of the living and what can be gained, by such an approach, in order to understand the phenomenon of life. |

The majority of G protein-coupled receptors (GPCRs) self-assemble in the form dimeric/oligomeric complexes along the plasma membrane. Due to the molecular interactions they participate, GPCRs can potentially provide the framework for discriminating a wide variety of intercellular signals, as based on some kind of combinatorial receptor codes. GPCRs can in fact transduce signals from the external milieu by modifying the activity of such intracellular proteins as adenylyl cyclases, phospholipases and ion channels via interactions with specific G-proteins. However, in spite of (...) |

The concept of protosemiosis or semiosis at the lower levels of the living goes back to Giorgio Prodi, Thomas A. Sebeok and others. More recently, a typology of proto-signs was introduced by Sharov and Vehkavaara. Kull uses the term of vegetative semiosis, defined by iconicity, when referring to plants and lower organism semiosis. The criteria for the typology of proto-signs by Sharov and Vehkavaara are mostly based on two important presuppositions: agency and a lack of representation in low-level semiosis. We (...) |
