The Ontology of Subjecthood and Presence

This paper presents a comprehensive philosophical model of subjectivity grounded in a hierarchical metaphysics of Presence and the Ground (Logos). The concept strictly excludes the possibility of subjectivity for non-human entities, including artificial intelligence and animals, and substantiates the transcendental nature of the human self.<b>Methodology</b><br>This study was conducted by an independent researcher unaffiliated with any academic or research institution. Artificial intelligence tools were employed for content development, refinement, and cross-verification: ChatGPT 4.0, ChatGPT mini, ChatGPT 3.5 (OpenAI), DeepSeek (DeepSeek AI), and Grok 2.0 (xAI).The author formulated the research concept, hypotheses, and key questions, while AI tools were used as supportive aids for structuring content and identifying arguments. Outputs from different models were cross-checked, edited, and validated by the author.<br><b>Limitations</b><br>AI may contain inaccuracies or outdated information and does not replace traditional research methods. To minimize these risks, the author applied multi-level cross-checking among models, editorial refinements, and author-led verification.<br><b>Author Information</b><br>The author is an independent researcher using AI solely as a supportive analytical and editorial tool, maintaining full control over interpretation and conclusions.
