Diagrams and alien ways of thinking

Area of Science:

• Astrobiology
• Philosophy of Mind
• Logic and Reasoning

Background:

• The discovery of numerous exoplanets increases the likelihood of extraterrestrial intelligence.
• Current methods for designing interstellar messages lack robust testing frameworks.
• There's a need to move beyond anthropocentric assumptions in communication strategies.

Purpose of the Study:

• To propose alternative frameworks for designing interstellar messages.
• To explore non-linguistic forms of logical reasoning for extraterrestrial communication.
• To investigate the potential of diagrammatic representations in METI.

Main Methods:

• Analysis of C. S. Peirce's Existential Graphs as a model for diagrammatic reasoning.
• Conceptual exploration of how logical inferences can be represented through qualitative sign transformations.
• Argumentation for diagrammatic systems as less convention-dependent than symbolic logic.

Main Results:

• Diagrammatic reasoning offers a viable alternative to symbolic logic for representing inferences.
• Transformations of qualitative signs can underpin logical reasoning without symbolic notation.
• Diagrams may be generalizable across different sensory modalities, including non-visual ones.

Conclusions:

• METI researchers should incorporate diagrammatic representations into their message design strategies.
• Diagrammatic reasoning may provide insights into the cognitive structures of alien minds.
• Studying diagrammatic reasoning can illuminate fundamental aspects of human reasoning itself.
