Subjectivity is a philosophical concept of how one, as a subject, gains the sense of identity through the interaction with the external world. The theorization on the conception of subjectivity itself has ranged from the early modern thinkers to post-modern thinkers. This research’s objectives are to describe the struggle of Stephen Dedalus, the main character in James Joyce’s novel entitled A Portrait of The Artist As A Young Man, to gain his identity as a form of subjectivity, and to describe  how  the  model  of  subjectivity  is  reflected  through  the  character  of Stephen Dedalus. This research is a discriptive qualitative research with philosophical approach.  From the  analysis,  first,  it  is found  out that  Stephen Dedalus underwent a journey of figuring himself out through a series of events that profoundly shape his sense of identity. The involvement of many external factors like the field of art, religion, and nationality is important in constructing Stephen Dedalus’ subjectivity. Secondly, by taking into account the theorization on the idea of subjectivity from the early modern philophers such as Rene Descartes and Immanuel Kant, to the post-modern philosophers such as Sigmund Freud and Jacques Lacan, it can be seen that Stephen Dedalus’ stream of consciousness as the main tool in perceiving his journey of life embodies the early modern conception that subjectivity is grounded on one’s independent consciousness.
