[EDIT: I learned this is not a syllogism, just a regular old argument. Syllogisms have only three propositions. Sigh.]
Here is my clearest articulation yet of the conjecture’s chain of causation, in the form of a seven-line syllogism:
Suffering comes from a catastrophic injury to the psyche; the psyche is a system of an organism; organisms are self-healing; healing requires vital energy; vital energy accumulates during rest; psychic rest is most profound in absolute darkness; therefore, darkness is the solution to inordinate suffering.
