In the vast realm of art and philosophy, there are intersections that connect deep philosophical concepts with the visual expression of art. This research explores one such intersection, namely the manifestation of Martin Heidegger’s concept of “anxiety / worry” in the works of Ali Akbar Sadeghi, an innovative Iranian artist. The research question is to examine how the concept of anxiety, as an existential structure in Heidegger’s ontological philosophy, is represented in the symbols, colors, and forms of Sadeghi’s art, which, by combining surrealism and traditional Iranian painting, creates a multilayered world of myths and human themes. This issue is important because differences in media (philosophy vs. art) and cultural context (West vs. Iran) can provide new interpretations of anxiety.The aim of the research is to discover and explain how this philosophical concept is manifested in Sadeghi's works, to create a bridge between existentialist philosophy and contemporary Iranian art, and to present a new perspective for a deeper understanding of anxiety in Heidegger's thought. This study, with an interdisciplinary approach, uses interpretative and descriptive analytical methods and, by purposefully selecting five works by Sadeghi, analyzes the reflection of anxiety in the context of Iranian culture. This research not only leads to a deeper understanding of Sadeghi's works, but also shows the capacity of art in explaining philosophical concepts and provides a basis for rethinking the relationship between art and philosophy in the Iranian context.This research aims to recover the concept of Sorge (Sorge) directed at Heidegger's Dasein in Ali Akbar Sadeghi's paintings, using a qualitative approach with analytical-interpretive and descriptive-analytical methods. The data include Heidegger's philosophical texts and five selected works of Sadeghi (selected based on the criteria of diversity of time period, execution techniques, richness of content related to Sorge, and accessibility). The research process is carried out in three stages: 1) Data collection through the study of Heidegger's texts and visual examination of Sadeghi's works with a focus on symbols, colors, and forms; 2) Data analysis using the visual content analysis method to identify the reflection of Sorge and compare it with Heidegger's philosophical interpretations; 3) Writing a report including the presentation of findings and conclusions. Research tools include library resources and visual analysis software.The variables include Parva (independent variable), its reflection in Sadeghi's works (dependent variable), and intervening variables (symbols, colors, forms, and philosophical themes).In Being and Time, Martin Heidegger introduces Sorge as the fundamental structure of Dasein (human existence), which expresses the existential conflict of man with the world and his own existence (Hai. Sorge, beyond a psychological state, is an ontological phenomenon that consists of three temporal aspects of Dasein: “being-beyond-self” (future), “being-already-in-the-world” (past), and “being-alongside” (present). Dasein is a being that is concerned with its own existence, is thrown into a world and actively participates in it. Sorge moves Dasein from inauthenticity and conformity with the collective towards individuality and acceptance of responsibility for its choices. Unlike Kierkegaard, who saw concern as psychological, Heidegger presents it on an abstract and ontological level. Awareness of death as “the possibility of non-existence” "Possibility" helps to free oneself from an inauthentic life.Prussia, which in Heidegger's later thought is linked to the historical truth of Dasein, defines man as the guardian of existence.Dasein is a central concept in the philosophy of Martin Heidegger. This German word literally means “being there.” Heidegger uses the concept to refer to a specific way of being that is unique to humans. Dasein is not simply a synonym for “human,” but rather refers to a specific way of being in which humans are engaged. One of the essential characteristics of Dasein is “being-in-the-world.” This concept suggests that Dasein is always situated in a global context and cannot be considered in isolation from its world. In Heidegger’s philosophy, Dasein is a key concept that refers to human existence. But Dasein is more than an individual human being. It refers to the way humans are in the world, their understanding of their own existence, and their interaction with the world around them.Dasein is considered a way of being that is associated with self-awareness, choice, and the ability to foresee the future. In other words, Dasein is “in the truth” and is considered the most authentic truth of human existence. Heidegger believes that Dasein is fundamentally related to anxiety or care. This anxiety separates Dasein from the everyday and leads to the question of the meaning of existence. Anxiety includes three temporal dimensions: the past (the fact of being), the present (falling), and the future (being). The concept of Dasein in Heidegger’s thought is different from the traditional concept of “existentia”. While existentia in traditional philosophy refers to everything that is available or present, Heidegger defines Dasein as a being whose existence is at stake and for whom it is vital. In other words, Dasein is a being that is constantly confronted with its existential possibilities and must decide about them.The concept of “revelation” or “purification” is of particular importance in relation to Dasein. Dasein as “purification” makes spatial orientations possible and conceals objects in accessible light and in darkness.
