Much of the scientific process involves “selective ignorance”: we include certain aspects of the systems we are considering and ignore others. This is inherent in the models that we utilize as proxies for biological systems. Our goal usually is to isolate components of these systems and consider them at only certain temporal and spatial scales. The scales and questions induce different metrics for what might be considered a “good” model. The study of mathematical and computational models is replete with differing (...) views of the terms verification, validation, corroboration, and so on. I have often argued that criteria for determination of model utility should be established prior to model construction, but this is rarely done in the application of models in biology. The question I address is whether it is feasible to develop a general approach to model evaluation, that includes all the forms of models typically applied in biology—animal and cell/tissue culture ones as well as mathematical and computational ones.

Four sequential, sub-processes are identified as the fundamental steps in the processing of signals by big-brained animals. These are, Detection of the signal, its Representation in correlated sensory brain structure, the Interpretation of the signal in another part of the brain and the Expression of the receiver’s response. We label this four-step spatiotemporal process DRIE. We support the view that when the context within which such signals are produced and received is relatively constant, the DRIE process can be ultimately assimilated (...) into the genome, with the Interpretation sub-phase is markedly decreased in duration as speed and efficiency are maximized. With frequent repetition and learning, an analogous result can be attained epigenetically as exemplified in human word and text recognition, allowing tasks critical to primate social function to be accomplished with rapidity and accuracy.

Jeremiah is an artifact of terror.... Jeremiah is an artifact of hope.

Face recognition depends upon the uniqueness of each human face. This is accomplished by the patterns formed by the unique relationship among face features. Unique face-patterns are produced by the intrusion of random factors into the process of biological growth and development. Processes are described which enable a unique face-pattern to be represented as a percept in the visual sensory system. The components of the face recognition system are analyzed as is the manner in which the precept is connected through (...) microcircuits to a memory file so that the history of a perceiver’s encounters with a familiar face enables the perceiver to access a memory store that is a record of the outcome of past encounters with the perceived. The importance of the face recognition system in enabling humans to individuate members the social group is discussed, as well as the importance of face recognition in the development of the individual’s social identity and ability to be a collaborative member of the social groups to which it belongs. The role of prosopagnosia—the inability to recognize familiar faces—in furthering an understanding of the face recognition system is examined, as is its importance in demonstrating the crucial nature of face recognition in human social functions. It is proposed that human face recognition is not a unique phenomenon but is an elaboration of processes existing in nonhuman primates as well as in lower animals. (shrink)

This paper is divided into two parts. Part I focuses on the manner in which the components of the face recognition system work together so that a perceiver, within several hundred milliseconds after seeing a familiar face, is able to both identify the face of the perceived and recall elements of the history of past encounters with the perceived. Face recognition plays a crucial role in enabling both human and nonhuman primates to interact in collaborative social groups. This critical function (...) is accomplished through the unidirectional coded transfer of informational elements from one component to another. Although these informational elements themselves are not meaningful to the perceiving agent, they do nevertheless contain essential bits of information that are necessary for the final formation of the meaningful message. The structural components of the system are identified and the manner in which informational elements are coded and transferred sequentially from component to component in the brain of the perceiver is described. The independent, physically separated components in the face recognition system are bridged by an additional component, an “adaptor”, that mediates the transfer of informational elements from one component to another. The nature of the independent systems, and the manner by which the bridging or adaptor apparatus enables coded information transfer from one system to another is discussed. Part II focuses on the analysis of recognition in human-designed sign systems such as Braille and Morse code. Recognition in human-designed sign systems is notable for the stability of the link between sign and meaning. Face recognition is characterized as being subjective, indicating that the meaning of a sign to a perceiver is variable and dependent on context, whereas human-devised sign recognition is characterized as being objective, indicating that the meaning of a sign is context independent and invariant. Human-designed sign systems require the presence in brain of a referent world. An example of a referent world is the set of letters of the alphabet. Representations of this set are installed in the brain through social mediated learning. Human-designed sets of signs are created to correspond, via a code enabling adaptor structure, to referent worlds in the brain. Human-designed sign systems are the foundations for literacy, a capability only found in humans. (shrink)

In this article we argue that sustainable development is not a socio-ecologically friendly principle. The principle, which is deeply embedded in environmental law, policymaking and governance, drives environmentally destructive neoliberal economic growth that exploits and degrades the vulnerable living order. Despite seemingly well-meaning intentions behind the emergence of sustainable development, it almost invariably facilitates exploitative economic development activities that exacerbate systemic inequalities and injustices without noticeably protecting all life forms in the Anthropocene. We conclude the article by examining an attempt (...) to construct alternatives to sustainable development through the indigenous onto-epistemology of buen vivir. While no panacea, buen vivir is a worldview that offers the potential to critically rethink how environmental law could re-orientate away from its ‘centered’, gendered and anthropocentric, neoliberal sustainable development ontology, to a radically different ontology that embraces ecologically sustainable ways of seeing, being, knowing and caring.

Highlights the roles of intention and intentionality in social cognition.

Abstract A unique aspect of human communication is the utilization of sets of well- delineated entities, the morphology of which is used to encode the letters of the alphabet. In this paper, we focus on Braille as an exemplar of this phenomenon. We take a Braille cell to be a physical artifact of the human environment, into the structure of which is encoded a representation of a letter of the alphabet. The specific issue we address in this paper concerns an (...) examination of how the code that is embedded in the structure of a Braille cell is transferred with fidelity from the environment through the body and into the Braille reader’s brain. We describe four distinct encoding steps that enable this transfer to occur. (shrink)
