Abstract

This article stages a critical-philosophical encounter between Derridean deconstruction and Peircean biosemiotic theory focussing on the role and status of metaphor within each. It argues that the biosemiotic understanding of metaphor as a structuring principle informing the sign-activity of living organisms and processes offers an alternative understanding of a generalised metaphoricity of life as such and an account of what might be called biological text, textuality or even, biosemiotic intertextuality. The article argues that biological textuality obeys a logic of semiotic immanence that is distinct from the logic of différance and of the quasi-transcendental as thought by Derrida. On this basis it elaborates the way in which metaphor in biosemiotic theory, and also the generalised biological metaphoricity informing the text of life, function as radically non-representational, inferential, and hermeneutic operators which model the semiotic processes of life and thereby enable an epistemologically weak or, in a certain sense, non-philosophical realism.
