In The Origin of the Work of Art, Heidegger attempts to answer the question of what art is, as well as trying to find the origin of art itself. In his attempt Heidegger distinguishes between his ideas of “Work” and “Equipment”. While, at the heart of his argument in The Origin of the Work of Art, these ideas are important in their own right in Heidegger's philosophy. In this essay I will define, compare and contrast these two concepts. I will also explain the ideas of “Earth” and “World” presented by Heidegger to facilitate this goal. Finally, I will conclude the paper by summarizing the key concepts and their relationship to each other. To achieve the goal of defining and explaining both “Equipment” and “Work”; I will have to introduce and explain two other concepts prevalent in Heidegger's work. These are the concepts of “World” and “Earth”. First I will start with the notion of “World”. Heidegger writes: “The world is not the mere collection of countable or uncountable, familiar and unfamiliar things that are at hand” (Heidegger, p.170). Heidegger claims that the “World” is not simply an ontic concept that most of us perceive, a totality of matter existing within the material conception of “World”. Heidegger clearly explains, “The world worlds and is more fully in being than the tangible, perceivable realm in which we believe ourselves to be at home” (Heidegger, p. 170). Heidegger defines the “World” as an ontological concept, in which there is a network of significant relationships between Dasein and everything that is at hand. For example, a small table exists in a network of significant relationships because it indicates those who sit there regularly, from which the various conversations can then branch out has...... half of the paper ......and the work does yes that the earth is an earth" (Heidegger, page 172). Then he adds: “The opposition between world and earth is conflict” (Heidegger, page 174). We finally have the criteria for what “Work” is. Heidegger explains that work establishes a world and highlights the “Earth”. “The work is an instigation to this struggle” (Heidegger, page 175). This conflict opens the truth or, as Heidegger says, “Aletheia” to the observer of the “Work”. Struggle or “Conflict” is the process of a work of art that takes place within the work of art itself. In conclusion, the concepts of “Work” and “Equipment” that Heidegger presents in The Origin of the Work of Art can be summarized as follows. “Equipment” is defined by its use and “Work” is based on the “Earth” and “World” on which it was created. The essential importance of which cannot be underestimated for understanding Heidegger's message contained in the text.
