This article explores the metaphor of Science as provider of sharp images of our environment, using the epistemological framework of Objective Cognitive Constructivism. These sharp images are conveyed by precise scientific hypotheses that, in turn, are encoded by mathematical equations. Furthermore, this article describes how such knowledge is pro-duced by a cyclic and recursive development, perfection and reinforcement process, leading to the emergence of eigen-solutions characterized by the four essential properties of precision, stability, separability and composability. Finally, this article discusses (...) the role played by ontology and metaphysics in the scientific production process, and in which sense the resulting knowledge can be considered objective.

This is a short overview of the biological functions debate in philosophy. While it was fairly comprehensive when it was written, my short book ​A Critical Overview of Biological Functions has largely supplanted it as a definitive and up-to-date overview of the debate, both because the book takes into account new developments since then, and because the length of the book allowed me to go into substantially more detail about existing views.

This book is a critical survey of and guidebook to the literature on biological functions. It ties in with current debates and developments, and at the same time, it looks back on the state of discourse in naturalized teleology prior to the 1970s. It also presents three significant new proposals. First, it describes the generalized selected effects theory, which is one version of the selected effects theory, maintaining that the function of a trait consists in the activity that led to (...) its differential persistence or reproduction in a population, and not merely its differential reproduction. Secondly, it advances “within-discipline pluralism” (as opposed to between-discipline pluralism) a new form of function pluralism, which emphasizes the coexistence of function concepts within diverse biological sub-disciplines. Lastly, it provides a critical assessment of recent alternatives to the selected effects theory of function, namely, the weak etiological theory and the systems-theoretic theory. The book argues that, to the extent that functions purport to offer causal explanations for the existence of a trait, there are no viable alternatives to the selected effects view. -/- The debate about biological functions is still as relevant and important to biology and philosophy as it ever was. Recent controversies surrounding the ENCODE Project Consortium in genetics, the nature of psychiatric classification, and the value of ecological restoration, all point to the continuing relevance to biology of philosophical discussion about the nature of functions. In philosophy, ongoing debates about the nature of biological information, intentionality, health and disease, mechanism, and even biological trait classification, are closely related to debates about biological functions.

In this paper, we develop an organizational account that defines biological functions as causal relations subject to closure in living systems, interpreted as the most typical example of organizationally closed and differentiated self-maintaining systems. We argue that this account adequately grounds the teleological and normative dimensions of functions in the current organization of a system, insofar as it provides an explanation for the existence of the function bearer and, at the same time, identifies in a non-arbitrary way the norms that (...) functions are supposed to obey. Accordingly, we suggest that the organizational account combines the etiological and dispositional perspectives in an integrated theoretical framework.

This thesis proposes a re-conceptualisation of engineering practice that moves towards responding to the nature of our 21st Century (21C) predicament – the dynamic, turbulent, labyrinthine flux which has developed through the inhabitation of modern humanity in our open living world. It describes a philosophy and practices to achieve this. Key concepts are the context within which practice takes place and an integrated approach at the system level. Together these principles promote processes and practices that can design life situations which (...) are more desirable and feasible, not only for humanity but to strengthen our natural environment. This is active adaptive planning; it changes practitioners’ relationship with the world by providing spaces where the agenda is not “driven” by the “push” of the past but elicits the “pull” of future intentions. Using these approaches people are engaged collectively in processes that re-connect with context taking into account the relevant uncertainties across what are often articulated as “different” systems (e.g. social, environmental, technical) and between past, present, future. Further, it works the loops – performing ontological politics that is linking and knotting what emerges from these processes with all the potential stakeholders, mobilising resources, peers, allies and the public. The thesis identifies links between Socio-Technical Systems, Actor-Network Theory and process philosophy. This extends Actor-Network Theory which has already removed those intellectual constructs that disarticulated reality, focusing attention on practise, movement, the making and remaking of reality, or net-work-ing with the complex heterogeneous nature of agency. It envisages practitioners having an epistemology and ontology that is formed through being “out-and-about” in the world, making “translations”. Through embedding these ideas in the way engineers learn and in the processes that they use, engineering becomes a “putting through”, manoeuvring, dissolving boundaries, always being in action, moving towards sustaining with others, while recognising purpose, congruence and transforming as emergent properties. Through purposive imag(in)ing of different ways of sustainable doing and being integration can occur, reframing across methodology, epistemology, ontology and philosophy. (shrink)

In the course of investigating the living world, biologists regularly attribute semantic content to the phenomena they study. In this paper, I examine the case of a contemporary research program studying the navigation behaviors of ants and develop an account of the norms governing researchers’ ascriptions of semantic content in their research practices. The account holds that researchers assign semantic content to behaviors that reliably achieve a difficult goal-directed function, and it also suggests a productive role for attributions of semantic (...) content in the process of animal behavior research.
