There is a hidden geometry in nature, some of whose mathematical laws and Euclidean and non-Euclidean geometry have been identified today. Hegel is one of the philosophers who is considered an idealist and strongly believed in the role of the soul in a work of art. Hence, Hegel's thought is somehow related to the soul of the work and geometry. This research seeks to answer the question of what is the relationship between art and geometry, what role do geometric laws play in the metaphysical perception of space, and what effect do Hegel's thoughts and ideas have on expressing the spirit of phenomena in geometric form? The present research mainly deals with the topic of Hegel's ideas about the history of art and the importance of the geometric method along with the dialectical method for the perception and recognition of phenomena. Hegel considers art to be the same as beauty; because it deals with the spirit. In his opinion, the object has negativity within itself; with the destruction of the object, desire reappears. Desire is the emergence of negativity; a topic that later in the twentieth century, Žižek and Lacan have used in detail.
