This text delves into the philosophical conception of the subject, responding to contemporary intellectual trends that address the questioning or even the 'loss of the subject.' The author argues that a proper understanding of these doubts requires recognizing the historical and linguistic contexts involved, particularly the origin of the Latin term 'subiectum,' which originally conveyed the meaning of what we now call an 'object.' This semantic ambiguity and the historical lack of precise terminology have led to a situation where the subject remains either unclearly defined or interpreted in vastly different ways across various philosophical systems. The core of the text proposes a new understanding of the subject, viewing it not as a static substance but as an internally unified process of becoming—an event. In this framework, to be a subject means primarily to work upon oneself, maintaining continuity in some aspects while significantly striving for qualitative transformation and self-improvement. This change is not the result of passive evolution or automatic movement; rather, it is the ever-changing outcome of one's own strenuous activity and conscious effort to redefine one's own existence.
