Since the mid-19th century, philosophy has delved into languages emerging from demographic shifts, with recurring themes from utilitarianism to pragmatism. This investigation spans from Jeremy Bentham to Charles Sanders Peirce and William James, highlighting the proliferation of languages shaping human life across domains. Amidst the plethora of signs shaping human interaction with ecosystems, these philosophical ideas resonate in diverse currents seeking to understand internal and external relations. In this context, the study explores not only language interpretation but also production, emphasizing the symbiotic relationship between design and language across various contexts. Although the interpretation of design practices since the 19th century remains controversial, design's pervasive influence within this system is undeniable, institutionalized or not. This research thus investigates design as a language, examining its potential as a medium for collective cognition. Drawing on a literature review, the study posits that design embodies a language, necessitating a cognitive process for manifestation. Through this lens, considering the affective processes of signs on cognition, the study suggests that interpreting signs contributes to collective cognition and knowledge acquisition through design. Emphasizing a theoretical exploration rooted in specific philosophical currents, the study does not seek to establish a singular understanding of design and its actions but rather to delve into the potential for shared meanings within design, its production, and interpretation.
