Why Does One Consciousness Exist? V2.0

This paper addresses the fundamental philosophical question: Why does the One Consciousness exist? Rather than approaching this question through causal explanation, it is reformulated as an ontological inquiry into the conditions that make existence itself possible. The analysis begins from the indubitable fact that something exists, including experience and cognition, and demonstrates that finite entities, infinite regress, absolute nothingness, and materialistic explanations cannot provide a sufficient ground of existence. On this basis, the paper argues that the ultimate ground must be understood as a form of consciousness—not individual consciousness, but a primordial field in which phenomena appear and become manifest. This foundational ground is identified as the One Consciousness, which is shown to be necessarily singular, since plurality presupposes an underlying unity. The paper further proposes a cosmological model in which the universe emerges through the self-differentiation of the One Consciousness in order to enable self-recognition. Within this framework, human consciousness is interpreted as a localized expression of the One Consciousness, and philosophical inquiry is understood as a recursive process through which the One Consciousness directs its inquiry toward itself. The concept of ignorance is introduced as a structural condition that constrains cognition, allowing differentiation to be experienced as real separation. The evolution of consciousness is therefore interpreted as the progressive overcoming of this condition, culminating in the rediscovery of unity within multiplicity. In conclusion, the question “Why does the One Consciousness exist?” is shown to be equivalent to the question “Why does existence itself occur?”, and the most coherent answer is that the One Consciousness itself constitutes the self-subsisting ground of all existence, manifestation, and experience. Update (Version 2):Minor revisions have been made to improve conceptual clarity and logical precision, including clearer articulation of self-differentiation and the definition of ignorance as a structural condition of cognition.
