The distinction between “near” and “far” thinking seems to have a connection with the old distinction between a puzzle and a mystery.
(Quick recap: A puzzle has a definite solution; a mystery does not)
Near thinking is outstanding for solving puzzles, but breaks down when examining a mystery. There is too much that is uncertain and unknowable about mysteries to allow close analysis to provide useful conclusions.
When examining a mystery, the less rigorous, more intuitive nature of far-thinking is more useful. Where there is no definite solution, one must speculate in a somewhat irrational way in order to form an action plan.

Most people wouldn’t feel horror over crystalline entities eating their young, but they would go apeshit over human beings doing the same.
