The Philosophical Reconstruction of Existence, Cognition, and Value, and the Conditions for Human Subjectivity
An Era of Redefining Humanity Beyond Technology
The Future of Humanity Examined Through In-Depth Analysis of Ontology, Epistemology, and Axiology

As we enter an era where artificial intelligence (AI) generates human language, mimics thinking, and expands even into the domains of creation and judgment, discussions about technology are increasingly converging into questions about human existence itself. We are no longer simply beings that use technology but have been placed in a situation where we must redefine 'what we will exist as' together with technology. In particular, the emergence of generative AI demonstrates that even intelligence, language, and creativity, previously considered humanity's unique domains, can be technically realized, fundamentally shaking the existing understanding that has defined humans only from a functional perspective.

This change is not simply a technological shock but an event that reconstructs the very framework of human understanding. If the industrial revolution redefined human 'labor,' the AI revolution is redefining human 'thought and existence.' In the past, humans expanded the world through tools, but now tools have entered within human cognitive structures and are mediating the thought process itself. Because of this, humans are being redefined no longer as independent judging subjects but as complex beings entangled with technology.

Within this transformation, the most fundamental frameworks for understanding humans are the three axes of philosophy: Ontology, Epistemology, and Axiology. These three respectively address the questions of "what exists," "how do we know," and "what is right and important," forming the core foundations that constitute human thought and judgment structures. And the AI era is simultaneously reconstructing these three axes, and the direction of that change is creating a double tension that pushes humans from the center while simultaneously calling them back to the center.

 
■ Ontology: "What Exists?"
Ontology is the most fundamental domain of philosophy, exploring what can be said to exist in the world. Traditionally, ontology developed centered on physical reality. That is, objects that are located in time and space and exist independently of human perception were the standard of 'existence.' This position is represented by realism, and humans were understood as beings that discover a world that already exists.

However, modern philosophy understands existence in a more expanded way. Non-material elements such as social institutions, language, norms, and trust are also recognized as important existences constituting reality. Concepts such as money and the state are existences that transcend physical entity but exert powerful influence in the real world. This shows that existence is not simply 'what is objectively there' but 'what is socially constructed and maintained.'

The AI era expands this concept of existence even more radically. Faces of non-existent people are generated, videos that look real are created, and non-human subjects produce language. At this point, we face a fundamental question.

Does something that is perceived but does not physically exist, exist?

This question shifts the standard of existence from 'physicality' to 'cognizability.' Now existence is not simply what is in the world but becomes a structure constituted within data, algorithms, and human perception. That is, existence is no longer a fixed entity but a process endlessly generated within the interaction of technology and humans.

However, an important fact does not change within this change. That is the fact that humans are still the subjects that give meaning to existence. No matter how many images AI generates and how much information it produces, human interpretation is needed for it to be recognized as 'something.' Humans do not simply recognize existence but are 'beings that understand and give meaning to existence.'

Therefore, from an ontological perspective, the uniqueness of humans lies not in function or capability but in the ability to give meaning to existence. Humans do not simply experience the world but are beings that interpret that experience and connect it to their own lives. And precisely at this point, humans are fundamentally differentiated from AI.

 
■ Epistemology: "How Do We Know?"
Epistemology is a philosophical domain that explores the nature and conditions of knowledge. Traditionally, knowledge has been defined as 'justified true belief.' That is, when something is true, there are reasons supporting that truth, and it is verifiable, we recognize it as knowledge. This perspective combined with scientific methodology made the discovery of objective facts the core of cognition.

However, in modern society we are already departing from these premises. Rather than directly experiencing the world, we understand it through the information environment provided by algorithms and platforms. News, search results, and recommended content are all information selected according to specific criteria, and we form knowledge within this filtered reality. That is, we no longer know 'the world as it is' but are perceiving 'a constructed world.'

AI makes this structure even more complex. Generative AI does not simply convey facts but generates the most plausible answer through probabilistic calculation. Different answers are possible to the same question, and the generation process is not transparently revealed to users. Due to this, the source and generation process of knowledge becomes increasingly unclear, and the boundary between fact and generated content blurs.

In this situation, epistemological questions fundamentally change.

Do we know, or do we merely trust what has been generated?

This question calls humans back to the center of cognition. What is now important is not the quantity of information but how that information is interpreted and verified. Humans must become not simple information recipients but beings that construct meaning and make judgments.

In particular, metacognition emerges as a core competency in the AI era. This is the ability to examine one's own thought processes, recognize the limitations of information, and independently review the basis of judgments. AI can provide answers, but in what context those answers were generated and what premises they carry cannot be judged by itself. This role still remains with humans.

Ultimately, from an epistemological perspective, the essence of humans lies in being 'questioning beings.' Humans do not simply seek answers but are beings that decide which questions are important and set the direction of those questions. As long as this ability is maintained, humans can remain as subjects of cognition even in the AI era.

 
■ Axiology: "What Is Right and Important?"
Axiology is the domain that explores what humans consider important and judge to be right. Traditionally, humans have made value judgments through criteria such as ethics, aesthetics, and utility. These criteria have a degree of universality and have served as important foundations for maintaining human society.

However, in modern society, value criteria are becoming increasingly fluid and relative. Individual tastes, social contexts, and data-based evaluation systems have important influences on value formation. What is good and what is important are no longer fixed criteria but are endlessly reconstructed within environments and structures.

AI makes these value structures even more complex. AI operates centered on efficiency and optimization, proposing the fastest and most accurate choices. However, human life cannot be explained simply by efficiency. Humans sometimes maintain relationships through inefficient choices, make ethical decisions, and create meaning in life.

The most important problem of the AI era is the 'outsourcing' of value judgment. We are increasingly relying on algorithms to decide what to choose, what to consume, and what to consider important. In this process, humans are at risk of losing the subjectivity of judgment in exchange for convenience.

What is needed at this point is human 'practical wisdom.' This is not simple information or technology but the ability to judge what is right in complex situations and make responsible choices. AI can present optimal results through calculation, but cannot make the ethical judgment of why those results are right.

Also, in the AI era, 'the value of inefficiency' becomes important. Processes such as deliberation, hesitation, and debate may seem unnecessary from the perspective of efficiency, but human ethics and meaning are formed precisely within such processes. Humans are not simply beings that rapidly reach conclusions but beings that reflect on themselves and form responsibility in that process.

 
■ The Conditions of Human Subjectivity
Ontology, epistemology, and axiology are not separate concepts but an integrated system forming the structure of human thought. Existence gains meaning through cognition, cognition has direction through value judgment, and value determines the importance of existence in return.

In the AI era, this structure is being reversed and restructured. Existence is generated as data, cognition is mediated by algorithms, and value is reconstructed centered on efficiency. Within this change, three conditions are necessary for humans to remain as subjects.

First, humans must understand existence based on their own finitude and experience.
Second, humans must maintain cognitive ability to critically interpret information and reconstitute questions.
Third, humans must themselves set and take responsibility for value criteria that transcend efficiency.

When these three conditions are maintained, humans can position themselves as subjects of collaboration rather than subordination in their relationship with AI.

 
■ What Will Humans Not Give Up?
The core of the AI era is not the advancement of technology but human choice. What humans give up and what they protect to the end determines the future.

If humans stop asking questions, give up interpretation, and entrust value judgment to systems, humans will gradually be absorbed into technology. However, if humans maintain the attitude of questioning the meaning of existence, interpreting knowledge, and taking responsibility for values, AI will remain not as a replacement for humans but as a tool of collaboration.

Ultimately, humans are not function but existence, not information but interpretation, not efficiency but value. And it is holding onto these three things to the end that is the most fundamental condition for humans to remain human in the AI era.

AI is testing humans.
But the answer to that test lies not in technology but in human philosophy itself.
