It is necessary to seek out the origins of the modern world’s problems in their theoretical and intellectual infrastructures, which are based on concepts. This paper aims to study the modern crisis of identity from the viewpoint of the evolution of the Subject. The Subject is one of philosophy’s more complex concepts, and its complexity can be analyzed through its historical evolution. It has been connected with meanings such as subjectness, subjectivity, subjugation, and subjection, and each of these meanings contain a part of the Subject’s complicated definition. In addition to calling the concept of the human subject into question, this paper demonstrates that we are witnessing a rise in feelings of insecurity and meaninglessness. The paper will analyze three main concepts of the Subject, and an explanation of each with reference to history’s great philosophers.
