Solipsism
Solipsism is the view that only the observer's own mind can be known to exist with certainty. The external world, other minds, and even one's own body may be nothing more than representations within one's consciousness. It is the most extreme observer-centric position.
I. Time
| Extent | Finite |
| Ontological Status | Emergent |
| Grain | Continuous |
| Freedom | Non-Deterministic |
| Traversability | Linear |
| Dimensionality | One |
| Direction | Uni-directional |
Time is emergent — it exists only as a feature of the observer's conscious experience. Since only the observer's mind can be known to exist, time is whatever the mind experiences as temporal succession. Time is finite, continuous, linear, and uni-directional as experienced, but whether these features reflect anything outside the mind cannot be established.
II. Space
| Extent | Finite |
| Ontological Status | Emergent |
| Curvature | Undefined |
| Dimensionality | Three |
| Locality | Non-local |
Space is emergent and mind-dependent — it exists only as a structure of the observer's perceptual experience. Its curvature is undefined because the solipsist cannot establish that space has any objective geometry. It is non-local in the sense that all spatial experience is internal to the mind. Space is finite because the observer's experience is bounded.
III. Matter
| Extent | Finite |
| Ontological Status | Emergent |
| Conservation | Conserved |
| Dimensionality | Three |
| Locality | Non-local |
Matter is emergent — it is merely a representation within the observer's consciousness. Whether anything material exists outside the mind is unknowable. Matter is conserved and non-local only as features of the internal perceptual world. The solipsist cannot confirm that matter has any independent existence whatsoever.
IV. Observer
| Time Instance | Single |
| Space Instance | Single |
| Extent of Knowledge | Immediate |
| Retainment of Knowledge | Total |
| Physicality | Disembodied |
| Agency | Active |
| Number | Singular |
V. Energy
Finite and emerging — energy, like all physical phenomena, is a representation within the observer's consciousness. Conservation: Variable — energy "conservation" is a regularity within the observer's experience, but has no independently verifiable physical status. Usage: Multiple within the observer's representational experience.
VI. Information
Only the information within one's own mind is real — external information may not exist at all.
