A Semiotic Modern Synthesis: Conducting Quantitative Studies in Zoosemiotics and Interpreting Existing Ethological Studies through a Semiotic Framework

In this paper, I present an argument that quantitative behavioural analysis can be used in zoosemiotic studies to advance the field of biosemiotics. The premise is that signs and signals form patterns in space and time, which can be measured and analysed mathematically. Whole organism sign processing is an important component of the semiosphere, with individual organisms in their Umwelten deriving signs from, and contributing to, the semiosphere, and vice versa. Moreover, there is a wealth of data available in the traditional ethology literature which can be reinterpreted semiotically and drawn together to make a cohesive biosemiotic whole. For example, isolated signals, such as structural elements of birdsong, are attributed meaning by an interpreter, thus generating new ideas and hypotheses in both biology and semiotics. Furthermore, animal behaviour science has developed numerous test paradigms that with careful adaptation, could be suitable for use within a Peircean tripartite model, and thus give valuable insights into Umwelten of other species. In my conclusion, I suggest that by bringing together traditional ethology and biosemiotics, it is possible to use the Modern Synthesis to provide context to biosemiosis, thus pragmatic meaning to animal signals. On this basis, I propose updating the Modern Synthesis to a Semiotic Modern Synthesis, which focuses on whole-organism signals and their contexts, the latter being derived from neo-Darwinian theory and the ‘Umwelt’. Thus, there need be no dichotomy; the Modern Synthesis can successfully be integrated with biosemiotics.

Was Adam Smith an evolutionary economist?: Smith’s study of botany and Charles Darwin’s theory of morality

This paper aims to extend and provide a new understanding of Adam Smith’s thoughts by focusing on some revisions in the 4th edition of The Theory of Moral Sentiments (Smith 1774), “the nutritional value theory of corn” in the Wealth of Nations, and then comparing Smith’s discourses on the formation of morality with C. Darwin’s. Smith’s understanding of human nature extended and deepened with the study of botany and other sciences at Kirkcaldy after spending 2 years in France as Duke Buccleugh’s tutor. He began to understand human nature not only as a composite of self-love and benevolence, but also of instinctual and experiential knowledge. Thus, Smith’s system transitioned to an evolutionary one, and he became an unconscious forerunner of the Darwinian theory of morality formation.

Randomness as Irrelevance

Under the neo-Darwinian theory, selection is the potter and variation is the clay: peculiarities or regularities of variation may emerge from internal causes, but these are ultimately irrelevant, because selection governs the outcome of evolution. Chapter 6 addresses this sense of “randomness” as irrelevance or unimportance, featuring (1) an analogical-metaphysical argument in which mutation is equated with raw materials or fuel, or is said to act at the “wrong level” to be an evolutionary cause; (2) direct empirical arguments; (3) mechanistic claims, e.g., claims about the ability of the “gene pool” to maintain variation, or of selection to be creative; (4) methodological claims to the effect that selection is amenable to study, but not mutation; and (5) an explanatory claim to the effect that mutation, though perhaps influential, only affects the boring parts of evolution. Appendix D provides quotations on the theme of unimportance.

Functionally Flexible Signaling and the Origin of Language

At the earliest break of ancient hominins from their primate relatives in vocal communication, we propose a selection pressure on vocal fitness signaling by hominin infants. Exploratory vocalizations, not tied to expression of distress or immediate need, could have helped persuade parents of the wellness and viability of the infants who produced them. We hypothesize that hominin parents invested more in infants who produced such signals of fitness plentifully, neglecting or abandoning them less often than infants who produced the sounds less frequently. Selection for such exploratory vocalization provided a critically important inclination and capability relevant to language, we reason, because the system that encouraged spontaneous vocalization also made vocalization functionally flexible to an extent that has not been observed in any other animal. Although this vocal flexibility did not by itself create language, it provided an essential foundation upon which language would evolve through a variety of additional steps. In evaluating this speculation, we consider presumable barriers to evolving language that are thought to be implications of Darwinian Theory. It has been claimed that communication always involves sender self-interest and that self-interest leads to deceit, which is countered through clever detection by receivers. The constant battle of senders and receivers has been thought to pose an insuperable challenge to honest communication, which has been viewed as a requirement of language. To make communication honest, it has been proposed that stable signaling requires costly handicaps for the sender, and since language cannot entail high cost, the reasoning has suggested an insurmountable obstacle to the evolution of language. We think this presumed honesty barrier is an illusion that can be revealed by recognition of the fact that language is not inherently honest and in light of the distinction between illocutionary force and semantics. Our paper also considers barriers to the evolution of language (not having to do with honesty) that we think may have actually played important roles in preventing species other than humans from evolving language.

A STUDY OF RELENTLESS SEARCH OF UTOPIA IN THOMAS HARDY’S TESS OF THE D’URBERVILLES USING JACQUES DERRIDA’S THEORY OF DECONSTRUCTION.

This paper aims to read Thomas Hardy’s Tess of the D’Urberviless in the light of Jacques Derrida’s Theory of Deconstruction, Darwinian Theory of Evolution in his book on the Origin of Species and each character’s search of Utopia in the entire novel. All the major characters have been taken in the novel as well as some of the minor characters also to study the novel in a better in a detailed manner.

The key role of underlying theories for scientific explanations. A darwinian case study

A given explanatory theory T falls into circular reasoning if the only way to determine its explanandum is through the application of T. To find an (often previous) underlying theory T′ that determines T′s explanandum helps us save T from this accusation of circularity. We follow the structuralist view of theories in presenting and dealing with this issue, by applying it to particular theories. More specifically, we focus on the relationship between the Darwinian theory of common ancestry and the determination of homologies.
