Dimension-by-Dimension Evidence
What each persona's writings reveal about their stance on each of the six dimensions.
Time
Leonardo da Vinci
Substantival and deterministic in the scientific notebooks — every natural phenomenon follows from prior causes. Leonardo treats time as a real medium within which cause and effect operate. Uni-directional: his geological observations assume deep, irreversible time.
Space
Leonardo da Vinci
Substantival, three-dimensional, local. Leonardo's perspective theory and engineering studies assume a Euclidean space in which objects interact through direct contact or visual rays. His cosmology, where it appears, is broadly Ptolemaic but disengaged from theological speculation.
Matter
Leonardo da Vinci
Substantival and conserved. Leonardo's anatomical and hydraulic studies treat matter as concrete stuff obeying discoverable laws — water flows, muscles contract, bones lever — with no appeal to substantial forms or occult qualities.
Observer
Leonardo da Vinci
The embodied human being equipped with the eye as the supreme instrument of knowledge. Active: the observer must experiment, dissect, draw, and measure. Plural: many such observers. No metaphysical agency: Leonardo's scientific investigations do not invoke God or the soul as explanatory principles.
Energy
Leonardo da Vinci
Finite and conserved within the mechanical systems Leonardo studied — levers, pulleys, water wheels. Irreversible: his observations of water flow and geological erosion assume a one-directional dissipation.
Information
Leonardo da Vinci
Substantival — knowledge is objective content drawn from nature by observation. Conserved cosmically (nature's laws are permanent). Personal information non-conserved: Leonardo shows no interest in personal immortality and his notebooks suggest a naturalist view of the soul.
Internal Tensions
Where each persona's working synthesis strains against itself.
Leonardo published nothing in his lifetime; the notebooks were scattered and partially lost after his death. His influence on natural philosophy was therefore indirect — Galileo, Bacon, and the seventeenth-century revolution rediscovered the empirical-mathematical method independently. The tension within the notebooks is between Leonardo the empiricist (who insists on observation) and Leonardo the theorist (who sometimes speculates far beyond his data — the flying machines, the perpetual-motion studies). His silence about religion is itself a tension: Leonardo lived in a thoroughly Christian society but his notebooks are nearly devoid of theological reflection.
