Phenomenalism

Time is emergent — it exists only as a pattern in the succession of sense impressions. Without perception, there is no time. Time is continuous, linear, and uni-directional as experienced through the flow of sense data. Its extent is finite because only actually perceived or perceivable temporal phenomena are real.

Space is emergent — it is constituted entirely by the spatial relations among sense data. Space has no independent existence beyond what is or could be perceived. Its curvature is undefined because the phenomenalist makes no claims about space beyond sense experience. Dimensionality is N because spatial structure depends on the observer's perceptual apparatus.

Matter is emergent — it is reducible to actual and possible sensory experiences (Mill's "permanent possibilities of sensation"). There is no underlying material substance behind the appearances. Matter is conserved only in the sense that stable patterns of sense data recur reliably, and local because all material knowledge is grounded in particular sense experiences.

Energy is emergent — it is a theoretical construct applied to stable patterns of sensory experience. Conservation holds as an observed regularity among phenomena, not as a metaphysical truth about an independent physical world. Dispersibility is irreversible within the flow of sense experience.

Information reduces to sense data — there is no deeper informational substrate behind the appearances. Sense data arise and vanish; there is no guarantee of informational persistence.
