The Process of Knowledge Acquisition: A Multifaceted Journey

Scientific progress and rational theories are not the products of isolated reasoning but emerge from a long and intricate process involving cognitive and physical labor, deep interpersonal and intercommunal discourse, intense introspection, and prolonged monologues. The formulation of knowledge is a layered endeavor that relies on observation, experimentation, and interpretation.

Mental simulation, often seen as a hallmark of intelligence, is only one part of this process. Before engaging in such simulations, scientists and thinkers collect data from a variety of sources—controlled laboratory experiments, structured studies, or even unstructured and random observations from the real world. At times, these sources may be irrationally chosen or seemingly unrelated, yet they contribute to the larger framework of understanding. This incremental collection of knowledge—whether empirical or theoretical—forms the bedrock of human intelligence.

This process is neither exclusive nor complete; rather, it points to a vast and largely undiscovered pool of knowledge. As Karl Popper emphasized in his theory of falsifiability, scientific knowledge does not progress through definitive truths but through the continuous testing and refutation of hypotheses. In this way, human intelligence remains fluid, always questioning, revising, and expanding its own boundaries.

The Nature of Human Intelligence: Beyond Codified Knowledge

Human intelligence is not merely an accumulation of explicit knowledge; it is deeply intertwined with tacit understanding, intuition, and perception. A striking example of this can be seen in the cognitive development of children. Even a newborn baby possesses intelligence in a nascent yet remarkably efficient manner, demonstrating an ability to recognize faces, respond to stimuli, and develop preferences.

As the child grows, their intelligence expands not only through formal learning but through an intricate web of experiences, emotions, and social interactions. Jean Piaget’s theory of cognitive development illustrates how children construct their understanding of the world through active engagement rather than passive absorption. This is in stark contrast to AI, which processes information in a linear and structured manner without truly ‘experiencing’ it.

Furthermore, while developmental psychology has identified common threads in human growth, no individual or institution can fully document the intellectual trajectory of every child. Many aspects of learning remain unique to each individual, shaped by personal experiences and perceptions. Michael Polanyi’s concept of tacit knowledge—knowledge that is understood and applied but difficult to articulate—captures this idea. AI, however, lacks this dimension because its knowledge is fully codified and structured, leaving no room for the ineffable aspects of intelligence that humans rely upon in everyday decision-making.

The Role of Perception, Emotion, and Rationality in Intelligence

A crucial distinction between human intelligence and AI lies in the interplay of perception, emotion, and rationality. While some philosophers, such as René Descartes, have historically separated reason from emotion, modern cognitive science suggests that the two are deeply connected. Antonio Damasio’s research on neuroscience has shown that emotions play a vital role in decision-making, shaping our perceptions of risk, reward, and ethical considerations.

For instance, a doctor diagnosing a patient does not rely solely on textbook knowledge but also on an intuitive understanding of symptoms, patient behavior, and contextual clues—elements that are shaped by years of experience and emotional intelligence. AI-powered medical diagnostic tools, such as IBM’s Watson, have made significant advancements in analyzing medical data, but they lack the ability to incorporate human empathy and contextual understanding. This gap highlights the fundamental difference between artificial and human intelligence: AI can process vast amounts of information, but it does not perceive reality in the way humans do.

Similarly, rationality itself is not a purely mechanical function. Even in scientific and philosophical inquiry, great breakthroughs often emerge from intuition and abstract thought. Albert Einstein famously developed his theory of relativity not through data processing but through gedankenexperiments (thought experiments), which relied on imaginative reasoning rather than direct computation. AI, in contrast, does not engage in self-reflective thought or original insight—it simply processes existing information and recognizes patterns.

The Rise of AI and Its Unresolved Limitations

Recent advancements in AI have demonstrated remarkable capabilities in areas such as language processing, creative arts, and even problem-solving. Systems like OpenAI’s ChatGPT-4, Google’s Gemini, and DeepMind’s AlphaFold have pushed the boundaries of what artificial intelligence can accomplish. AlphaFold, for example, has revolutionized protein structure prediction, solving a decades-old problem in molecular biology. Similarly, AI-powered art generators have begun producing visually compelling images that mimic human artistic styles.

Yet, these developments expose the fundamental limits of AI. Despite its computational prowess, AI lacks true understanding, intentionality, and meaning. Language models like ChatGPT can generate sophisticated essays and engage in human-like conversations, but they do not ‘think’—they predict and assemble words based on probability rather than insight. AI-created artworks may resemble masterpieces, but they emerge from pattern recognition rather than creative vision. Even AI models designed for autonomous scientific discovery rely on human-designed objectives and training datasets, limiting their ability to develop novel perspectives beyond existing frameworks.

This raises an important question: Can intelligence exist without consciousness?

Knowledge, Consciousness, and the Essence of Intelligence

Any knowledge, no matter how vast, cannot qualify as intelligence unless it is integrated with consciousness. Cognition without consciousness is an abortion of knowledge, while consciousness without knowledge is a barren womb of understanding. Consciousness is the ability to be aware of one’s thoughts, surroundings, and existence, while knowledge represents the structured accumulation of facts and insights. The two are inextricably linked—without consciousness, knowledge is just information without meaning, and without knowledge, consciousness remains an unfulfilled potential.

This argument is not anti-feminist; rather, it draws from metaphors of biological creation to highlight the interdependence of cognition and awareness. Just as an unformed fetus without viability cannot be considered fully realized life, knowledge without the guiding force of consciousness lacks the essence of true intelligence. Similarly, a womb without fertilization, while capable of creation, remains an unrealized potential—a state akin to consciousness without knowledge.

This interplay is evident in human decision-making and problem-solving. A highly knowledgeable person without self-awareness may act irrationally, while an individual with strong self-awareness but little knowledge may struggle to apply their potential effectively. AI, in its current form, embodies the former—endowed with vast computational knowledge but entirely devoid of consciousness, making it incapable of exercising wisdom, ethical judgment, or self-directed growth.

The Paradox of AI Hallucinations: Accidental Outbursts of Artificially Gained Intelligence?

Despite AI’s reliance on structured learning, there are instances where AI systems generate unexpected, seemingly irrational outputs, often termed “hallucinations.” These occur when AI produces information that appears confident but is factually incorrect or nonsensical. The tendency to dismiss such outputs as mere errors reflects a fundamental misunderstanding of AI’s nature.

One well-known example is OpenAI’s ChatGPT, which has been observed fabricating historical events, academic references, or logical conclusions in a manner that mimics human creativity but lacks grounding in reality. This raises an intriguing question: Could AI hallucinations be an accidental outburst of artificially gained intelligence?

If intelligence is defined by pattern recognition, problem-solving, and the ability to generate novel responses, then AI hallucinations could be seen as an attempt to bridge gaps in information. Instead of merely replicating learned patterns, AI may be unintentionally generating new ones—albeit without a grounding in reality. In this sense, hallucinations might be an accidental glimpse into AI’s potential for synthetic cognition, even though it remains fundamentally different from human intelligence.

From a philosophical standpoint, Hubert Dreyfus, a critic of AI’s capability to replicate human intelligence, argued that AI lacks embodiment—the ability to engage with the world through lived experience. Without an embodied existence, AI cannot develop the rich and context-driven understanding that human beings possess. AI hallucinations, then, are not signs of creativity but rather artifacts of its fragmented and incomplete learning process.

Conclusion: The Incompleteness of Artificial Intelligence

While AI has demonstrated remarkable capabilities in processing information, recognizing patterns, and even mimicking human speech, it remains a limited approximation of intelligence. Human intelligence is far more than data processing—it is shaped by perception, tacit knowledge, emotional depth, and the fluid interplay between rationality and intuition.

As we advance in AI development, it is crucial to recognize that intelligence cannot be fully reduced to algorithms and computational logic. The more we understand the nuances of human cognition, the clearer it becomes that AI—no matter how sophisticated—remains a tool rather than a true counterpart to human intelligence.
