Mechanism realists assert the existence of mechanisms as objective structures in the world, but their exact metaphysical commitments are unclear. We introduce Local Hierarchy Realism (LHR) as a substantive and plausible form of mechanism realism. The limits of LHR reveal a deep tension between two aspects of mechanists’ explanatory strategy. Functional decomposition identifies locally relevant entities and activities, while these same entities and activities are also embedded in a nested hierarchy of levels. In principle, a functional decomposition may identify entities (...) engaging in causal interactions that crosscut the hierarchical structure of composition relations, violating the mechanist’s injunction against interlevel causation. We argue that this possibility is realized in the example of ephaptic coupling, a subsidiary process of neural computation that crosscuts the hierarchy derived from synaptic transmission. These considerations undermine the plausibility of LHR as a general view, yet LHR has the advantages that (i) its metaphysical implications are precisely stateable; (ii) the structure it identifies is not reducible to mere aggregate causation; and (iii) it clearly satisfies intuitive and informal definitions of mechanism. We conclude by assessing the prospects for a form of mechanism realism weaker than LHR that nevertheless satisfies all three of these requirements. (shrink)

Literature on epistemic injustice has grown tremendously as an increasingly rich and diverse body of work in recent years. From the point of view of intercultural and anticolonial discussions, contemporary contributions have also helped to illuminate how epistemic injustice and other forms of cultural domination might be related to essential processes within the structures of colonial and racial supremacy. -/- This proposal aims to contribute to such relevant and illuminating discussions by focusing on the role that language and culture might (...) have in phenomena of epistemic injustice, particularly, hermeneutical injustice. Despite the central role played by semantics in epistemic injustice studies, the question about whether certain languages could also themselves be the recipients of epistemic injustice has been rather undertheorized. Simultaneously, recent movements to advocate for minority language rights, such as the Linguistic Human Rights Movement (LHR), raise important questions in this connection. -/- In the present paper, I argue that attending to the intercultural context reveals a new sort of hermeneutical injustice, one that, surprisingly, has never been articulated before. In particular, I am referring to a kind of HI that is essentially “linguistic” and “culture-specific”. I will be presenting two different subtypes for this kind of hermeneutical injustice: The first concerns the possibility of considering certain languages themselves as genuine objects of hermeneutical injustice, while the second has to do with certain specific culturally-established expressions or forms of talking.
