Semiotics of Biosignatures by David Dunér

In astrobiology biosignatures could be of various kinds, fossils, molecules, traces, artefacts, structures, electromagnetic waves, etc. The purpose of this article is to bring some semiotic order in this seemingly chaotic variation of signs.

Greimas and Levinas – Residents of Kaunas. War and Semiotic Theory in the Twentieth Century by Geoffrey Sykes (http://doi.org/10.33234/ssr.9.1)

This paper is the first in a series that will inquire about the status of semiotic theory in the twentieth century. It will address the tacit or unacknowledged influences of war, economics and mass migration, that shape the theory as narrative, and limits claims to its scientific or objective status. This part will focus on the prominent French semiotician Algirdas Julien Greimas, with reference to the IASS 2017 Congress, held at Kaunas Lithuania. It will also mention the eminent thinker Emmanuel Levinas.
