Dimension-by-Dimension Evidence

What each work's passages reveal about its stance on each of the six dimensions.

Time

The Book of Beliefs and Opinions

The world was created from nothing — Saadia provides four proofs for creation. Time is finite (it begins with creation), linear, and eschatological (moving toward messianic redemption). Non-deterministic: free will is essential for divine justice.

Space

The Book of Beliefs and Opinions

Finite, substantival, three-dimensional. The created cosmos is bounded. Standard kalam-Ptolemaic framework.

Matter

The Book of Beliefs and Opinions

Created from nothing — non-conserved in the ultimate sense. God created matter and can annihilate it. Saadia argues against the eternity of matter and against dualist cosmologies.

Observer

The Book of Beliefs and Opinions

The observer has four sources of knowledge: sense perception, rational intuition, logical inference, and reliable tradition (including revelation). Knowledge is mediated through these channels. Active agency in the pursuit of truth. Plural observers within the covenantal community.

Energy

The Book of Beliefs and Opinions

Divine creative power sustains the cosmos. Finite, conserved within the created order. Standard kalam framework.

Information

The Book of Beliefs and Opinions

Torah (written and oral) is the permanent revelatory record. Rational truths are timelessly valid. Personal information conserved: the soul is immortal, and bodily resurrection is affirmed.

Internal Tensions

Where each work's argument pulls against itself.

The Book of Beliefs and Opinions

If reason can prove everything revelation teaches, revelation seems redundant. Saadia's answer (revelation saves time and reaches the masses) is practical, not principled. The kalam method borrowed from Islam raised suspicions that foreign categories were being imported into Torah.
