The Fourth Perspective: Evolution and Organismal Agency

This chapter examines the deep connections between biological organization, agency, and evolution by natural selection. Using Griesemer’s account of the re- producer, I argue that the basic unit of evolution is not a genetic replicator, but a complex hierarchical life cycle. Understanding the self-maintaining and self-proliferating properties of evolvable reproducers requires an organizational account of ontogenesis and reproduction. This leads us to an extended and disambiguated set of minimal conditions for evolution by natural selection—including revised or new principles of heredity, variation, and ontogenesis. More importantly, the continuous maintenance of biological organization within and across generations im- plies that all evolvable systems are agents, or contain agents among their parts. This means that we ought to take agency seriously—to better understand the concept and its role in explaining biological phenomena—if we aim to obtain an organismic theory of evolution in the original spirit of Darwin’s struggle for existence. This kind of understanding must rely on an agential perspective on evolution, complementing and succeeding existing structural, functional, and processual approaches. I sketch a tentative outline of such an agential perspective, and present a survey of methodological and conceptual challenges that will have to be overcome if we are to properly implement it.

Hegel's Organizational Account of Biological Functions

Two concepts have polarized the philosophical debates on functions since the 1970s. One is Millikan's concept of ‘proper function’, meant to capture the aetiology of biological organs and artefacts. The other is Cummins's concept of ‘dispositional function’, designed to account for the real work that functional devices perform within a system. In this paper I locate Hegel's concept of biological function in the context of those debates. Admittedly, Hegel's concept is ‘etiological’, since in his account the existence of purposive organs is explained by appeal to their purpose, yet, against Millikan's concept, Hegel's does not presuppose the phenomenon of natural selection nor derives the function of tokens from the function of types. So, my aim is, first, to present Hegel's approach to biological functions as one neither purely etiological nor purely dispositional. It will appear rather as an example of an organizational account (as those advocated today by McLaughlin, Mossio and others), that attributes function according to present performances (unlike etiological accounts) and emphasizes the role of functional parts in their self-production within the system they belong to (unlike dispositional accounts). Finally, I briefly discuss how Hegel's concept performs against common objections to organizational accounts.

Silencing/Voicing Transgender People at Work: An Organizational Perspective

Narratives are a means of voicing in organizations. What it follows is a short reflection concerning the challenge taken by narratives of being the lens through which hearing voice from transgender people in organizations. This paper is aimed to scrutinize in what extent the role of transgender people narratives aids inclusion in organizations, through an organizational account of the underlying meanings in writing organizational stories. The reflection is mainly based on two concepts: the first one is silence, as a way to hide themselves in the workplace, and the second one is identity, as an apparatus of comparison between individual and organizational subjectivity. In this reflection, transgender people played the role of being a source of knowledge, triggering a debate concerning voice and silence in organizations.
