This study examines Nelson Goodman’s theory of irrealism and worldmaking as a philosophical framework for analyzing modern art, particularly within the avant-garde movements of Cubism and Surrealism. Goodman challenges the traditional view of reality as a fixed and objective entity, proposing instead that it is constructed through symbolic systems such as language, science, and art. In this sense, Goodman’s philosophy represents a radical shift from the realist conception of an independently existing world. Instead of being a passive receiver of external stimuli, human cognition actively participates in shaping our understanding of the world. By recognizing reality as a construct of symbolic systems, Goodman invites us to reconsider our perception of the external world, emphasizing that art, like language, creates reality rather than simply mirroring it. Goodman’s irrealism holds that reality is not merely given or found, but rather made through various symbolic frameworks. He rejects the notion of an objective, independent reality and posits that human beings can construct multiple realities based on different symbolic structures. This conceptual shift enables a deeper understanding of modern art, particularly in its ability to challenge conventional perceptions of space, time, and identity. Through symbolic systems, artists are not simply reflecting the world around them but are actively creating new realities, opening up possibilities for understanding human experience in ways that were previously unimagined. The central research question guiding this study explores how Goodman’s theory can be applied as a tool for analyzing modern art, particularly in its transformation of reality. Specifically, the study examines two iconic works: Les Demoiselles d'Avignon by Pablo Picasso and The Persistence of Memory by Salvador Dalí, which were chosen for their significant roles within the Cubist and Surrealist movements. Both of these masterpieces represent moments in the history of art when traditional modes of representation were broken, offering profound insights into how artists engage with the process of worldmaking. The research aims to apply Goodman’s conceptual framework to these two pivotal works to demonstrate how they transcend traditional forms of representation. Picasso’s Les Demoiselles d'Avignon challenges classical norms of anatomy and perspective, creating a symbolic system that aligns closely with Goodman’s notion of worldmaking. Through the use of geometric abstraction and the simultaneous presentation of multiple perspectives, Picasso offers a fragmented, multifaceted version of reality that directly challenges the concept of a single, objective world. In deconstructing the human figure, Picasso reinterprets it as a series of shapes and forms that exist within a dynamic and evolving symbolic system. This approach suggests that reality is not fixed or singular but is open to transformation through the way humans structure and represent it. Through his innovative technique, Picasso questions the very foundation of artistic representation, showing how art can invent rather than replicate the world. Similarly, Salvador Dalí’s The Persistence of Memory exemplifies Surrealism’s ability to merge reality with imagination, blurring the boundaries between the real and the imaginary. In this iconic painting, Dalí uses the surrealist technique of dreamlike imagery to dissolve traditional notions of time and space. The melting clocks, which appear to ooze and distort across the canvas, challenge conventional perceptions of temporality and permanence. The bizarre landscape, with its desolate, almost otherworldly quality, further invites the viewer to reconsider the nature of reality itself. Through this symbolic blending of the real and the fantastic, Dalí creates a new, surreal symbolic reality that echoes Goodman’s ideas of worldmaking. The symbolic density within Dalí’s work creates multiple layers of meaning, inviting viewers to engage with a reality that is as subjective as it is transformative. Dalí’s work is deeply rooted in Freudian psychoanalysis and draws from personal imagination, reflecting how art can fundamentally alter human understanding of existence by proposing alternative ways of seeing and experiencing the world. The methodology of this study combines philosophical analysis with detailed case studies of Picasso’s and Dalí’s works. Goodman’s theoretical concepts, such as symbolic systems, multiple worlds, and the construction of reality, are applied to interpret the selected artworks. Through this framework, the study unpacks the symbolic and conceptual innovations present in both Les Demoiselles d'Avignon and The Persistence of Memory. These works serve as case studies for understanding how modern artists use art to create new symbolic systems that actively participate in the construction of reality. In both cases, the artists are not merely depicting the world as it appears but are creating new realities that force the viewer to reconsider what is “real” and how reality can be perceived. The findings of the study reveal that both Les Demoiselles d'Avignon and The Persistence of Memory actively engage in worldmaking by redefining reality through the creation of new symbolic systems. Picasso’s rejection of traditional artistic norms, particularly in his approach to the human body and space, is not merely a stylistic choice but a profound commentary on the nature of reality itself. His work suggests that reality is fragmented and multifaceted, requiring new ways of seeing and interpreting the world. Through his geometric abstraction, Picasso makes the case that reality is not an objective, immutable structure but an ever-changing system of symbols that can be reinterpreted in countless ways. Dalí, on the other hand, uses surreal imagery to merge the real and the imaginary, breaking down the boundaries between the physical world and the world of dreams. In doing so, he challenges traditional ideas of time, space, and memory. The melting clocks in The Persistence of Memory serve as a symbol of the fluidity and subjectivity of time, while the distorted landscape suggests the mutability of space. Dalí’s work thus provides a unique example of how art can reshape our understanding of reality by creating a symbolic system that is simultaneously familiar and strange, offering new ways of engaging with the world. While the study demonstrates the utility of Goodman’s framework, it also acknowledges certain limitations. The exclusive focus on two works, while providing an in-depth analysis, limits the generalizability of the findings to a broader range of modern art. Additionally, Goodman’s notion of symbolic density remains a subject of ongoing debate among scholars, and further exploration is needed to clarify its implications for art analysis. The qualitative nature of the research introduces an element of subjectivity, which could affect the replicability of interpretations. Despite these limitations, the study contributes significantly to both philosophical aesthetics and art history by bridging Goodman’s theoretical insights with modern art practices. In conclusion, this research demonstrates that Goodman’s theory of irrealism and worldmaking offers a comprehensive framework for understanding the transformative power of modern art. Through the deconstruction of traditional modes of representation and the creation of new symbolic systems, artists like Picasso and Dalí redefine the boundaries of art and human perception. Their works exemplify art’s capacity to create alternative realities and offer new ways of understanding the world. This study highlights the critical role of modern art in shaping both individual and collective consciousness, and it opens up new avenues for interdisciplinary research in philosophy of art, art history, and the digital humanities.
