The scientific study of living organisms is permeated by machine and design metaphors. Genes are thought of as the ‘‘blueprint’’ of an organism, organisms are ‘‘reverse engineered’’ to discover their functionality, and living cells are compared to biochemical factories, complete with assembly lines, transport systems, messenger circuits, etc. Although the notion of design is indispensable to think about adaptations, and engineering analogies have considerable heuristic value (e.g., optimality assumptions), we argue they are limited in several important respects. In particular, the (...) analogy with human-made machines falters when we move down to the level of molecular biology and genetics. Living organisms are far more messy and less transparent than human-made machines. Notoriously, evolution is an opportunistic tinkerer, blindly stumbling on ‘‘designs’’ that no sensible engineer would come up with. Despite impressive technological innovation, the prospect of artificially designing new life forms from scratch has proven more difficult than the superficial analogy with ‘‘programming’’ the right ‘‘software’’ would suggest. The idea of applying straightforward engineering approaches to living systems and their genomes— isolating functional components, designing new parts from scratch, recombining and assembling them into novel life forms—pushes the analogy with human artifacts beyond its limits. In the absence of a one-to-one correspondence between genotype and phenotype, there is no straightforward way to implement novel biological functions and design new life forms. Both the developmental complexity of gene expression and the multifarious interactions of genes and environments are serious obstacles for ‘‘engineering’’ a particular phenotype. The problem of reverse-engineering a desired phenotype to its genetic ‘‘instructions’’ is probably intractable for any but the most simple phenotypes. Recent developments in the field of bio-engineering and synthetic biology reflect these limitations. Instead of genetically engineering a desired trait from scratch, as the machine/engineering metaphor promises, researchers are making greater strides by co-opting natural selection to ‘‘search’’ for a suitable genotype, or by borrowing and recombining genetic material from extant life forms.

Comments and reports on synthetic biology often focus on the idea that this field may lead to synthetic life or life forms. Such claims attract general attention because “life” is a basic concept that is understood, interpreted and explained in multiple ways. While these different understandings of life may influence the ethical assessment of synthetic biology by experts and the public, this field might, in turn, influence how academics or the public view life. We suggest in this paper that synthetic (...) biology provides an opportunity to discuss and compare different views and explanations of the world, starting from the concept of life. We argue that a narrow focus on just one interpretation of this concept may be harmful and that people will benefit from being aware of a diversity of understandings of life because they provide answers to different questions. Moreover, the confrontation among views is important for the development of reasoning abilities, and a nuanced view on our world will be useful for integrating scientific findings and their implications into a wider context. At the same time, we should not only consider other understandings of life for our own benefit but also because a moral attitude of respect for and toleration toward others implies permission to express and maintain their views. For these reasons, we suggest that a diversity of views on life should be included in public education and in public engagement events on synthetic biology. Moreover, they should be on the research agenda of technology assessment studies within the ELSA or RRI frameworks. (shrink)

In this paper, we examine the use of the term ‘life’ in the debates within and about synthetic biology. We review different positions within these debates, focusing on the historical background, the constructive epistemology of laboratory research and the pros and cons of metaphorical speech. We argue that ‘life’ is used as buzzword, as folk concept, and as theoretical concept in inhomogeneous ways. Extending beyond the review of the significant literature, we also argue that ‘life’ can be understood as aBurstwordin (...) two concrete senses. Firstly, terms such as life easily turn into fuzzy, foggy and buzzy clouds of nonsense, if their use is not appropriately reflected. In these cases, the semantic orientation is detonated. This is theBurstword Icharacteristic of the concept of ‘life’ that we reveal for its unclear terminological use. Secondly, and in contrast toBurstword I, we show that the concept of ‘life’ can be used in a methodologically controlled way. We call this kind of useBurstword II. Here the concept of ‘life’ fulfils the function of expanding an inadequately narrow disciplinary or conceptual focus in different discursive contexts. In this second sense, ‘life’ receives an important operational function, for instance as a transdisciplinary research principle. It turns out that the innovative function and paradigm-changing power of metaphorical speech belong here as well. Finally, we illustrate three ethically relevant examples that show how ‘life’ can be applied asBurstword IIin the context of synthetic biology. (shrink)

Finding an adequate definition of "life" has proven to be a tricky affair. In this article, I discuss the idea that nothing is really alive: we only say so. I shall argue that 'being alive' is not a genuine property of things, and that it only reflects the way we think and talk about things. An eliminativist strategy will then allow us to free ourselves from the burden of having to find a definition of life, and will allow us to (...) focus on the genuinely interesting properties of living (and non-living) entities.

Synthetic biology opens up the possibility of producing new entities not found in nature, whose classification as organisms or machines has been debated. In this paper we are focusing on the delimitation of the moral value of synthetic products, in order to establish the ethically right way to behave towards them. In order to do so, we use personalism as our ethical framework. First, we examine how we can distinguish between organisms and machines. Next, we discuss whether the products of (...) synthetic biology can be considered organisms at all and assess what their moral value is and how should we behave towards them. Finally, we discuss the hypothetical case of synthetic humans. (shrink)

From his earliest published writings to his last, Roman Ingarden displayed an interest in theoretical biology and its efforts to clarify what distinguishes living organisms from other types of entities. However, many of his explorations of such issues are easily overlooked, because they don’t appear in works that are primarily ontological, metaphysical, or anthropological in nature but are “hidden” within his works on literary aesthetics, where Ingarden sought to define the nature of living organisms in order to compare literary works (...) to such entities. This article undertakes a historical textual analysis that traces the evolution of Ingarden’s thought regarding the nature of the literary work of art as an organism-like entity and uncovers its links with the simultaneous development of his systems theory and its central concept of the “relatively isolated system”: for Ingarden, a literary work and an organism are each a systematically transforming, “living,” functional-structural whole that comprises a system of hierarchically arranged and partially isolated elements whose harmonious interaction allows the literary work or organism to fulfill its chief function. Having completed that historical analysis, we test Ingarden’s assessment of works of art as organism-like entities in a novel context by investigating the organism-like qualities of the contemporary computer game; insofar as their AI-driven behavior displays a form of agency, such games might appear to be even more “alive” than traditional works of art. We show that Ingarden’s conceptual framework provides a useful tool for understanding the “organicity” of such games as works of art, despite the fact that they differ qualitatively from those art forms with which Ingarden was directly familiar.

This essay examines how biocentric positions assess the aims and planned products of synthetic biology. In this emerging field, scientists and engineers aim at designing and producing new life forms by various procedures. In this paper I explore whether, for biocentrists, 1) synthetic organisms have moral standing and, 2) the process of synthesising living organisms has moral implications. Because naturalness plays a role in some biocentric theories, synthetic biology — at first sight — seems to challenge the idea that all (...) living organisms have moral standing. However, according to the interpretations that I offer, the biocentric positions discussed here would also assign moral standing to synthetic organisms. That living organisms have moral standing does not necessarily imply that it is morally problematic to synthesise them. However, different lines of biocentric argumentation suggest that in designing and synthesising living organisms, the moral standing of the product needs to be taken into account. This means among other things, that according to biocentrists, such procedures may lead to special responsibilities or require certain attitudes from scientists towards their products. (shrink)
