Ibn Tufayl

Both — the Necessary Existent is eternal; the physical world is generated within time. Ibn Tufayl follows the Avicennan line: the emanation from God is logically necessary and eternal, but sublunary processes unfold in linear time. Deterministic: the emanation proceeds by necessity, and Hayy's rational ascent is presented as the inevitable trajectory of a rational soul given nature and time.

Ibn Tufayl

The Ptolemaic-Aristotelian finite cosmos: concentric spheres governed by separate intellects. Hayy observes the heavens and deduces the structure. Space is substantival and finite, bounded by the outermost sphere.

Ibn Tufayl

Hylomorphic: sublunary matter is composites of prime matter and form, subject to generation and corruption. Hayy learns this by observation — dissecting the gazelle, studying fire, classifying minerals and plants. Matter is conserved through elemental transmutation.

Ibn Tufayl

The story's most distinctive claim: a singular observer (Hayy), entirely alone, can reach philosophical and mystical truth through reason and observation. The observer is embodied but ascends through intellectual stages to conjunction with the Active Intellect and ultimately mystical union. Cosmic-ordering: the culmination is participation in the necessary emanation. Variable personal conservation: the philosophical elite achieve intellectual immortality; the fate of the masses is left ambiguous.

Ibn Tufayl

Standard Avicennan framework: the celestial spheres transmit causal influence downward; the Active Intellect illuminates the sublunary world. Energy is finite, conserved, and the causal chain is irreversible (downward from the Necessary Existent).

Ibn Tufayl

Intelligible forms are eternally present in the Active Intellect. Hayy's acquisition of knowledge is a process of abstracting these forms from sensory experience. Information at the cosmic level is conserved in the intellects. Personal conservation is variable: the philosophical soul that achieves conjunction attains a kind of immortality, but the unphilosophical soul's fate is unclear.
