Taxonomically, lichens are classified as a distinct group under the Kingdom Fungi. They have been subject to materia medica books since the ancient times, drawing attention for their medicinal properties. Studies on the biology and history of lichens in Türkiye have now reached a significant level. Therefore, it is epistemologically plausible to consider lichens in philosophy and from a philosophical perspective. The dual nature of lichens known as symbiotic organisms leads to the emergence of certain properties that are not observable (...) when individual partners live separately. The present study explores whether lichens are indivisible individuals, discussing the lichen thallus as a relatively balanced system and even a miniature ‘ecosystem’. Consequently, this paper proposes that emergence, as a concept, can be considered a methodological apparatus in both defining and explaining biological facts and phenomena. Building on biological knowledge, it is suggested that philosophy, particularly biophilosophy and ethics, can consider lichens as model organisms. Through this perspective, principles for coexistence of both individuals, communities, and societies can be established. (shrink)
