Testing Theology With Optics: PARADISO, Canto II, Lines 85 - 105

Beatrice continues in her scientific and Scholastic explanation for moon spots by taking apart a secondary argument . . . and proposing an optical experiment.

She voices an objection Dante might have: perhaps there are dense bits behind the rare bits that reflect light as darker spots because those denser bits are farther off.

To prove him wrong (although he hasn't said a thing), she asks him to set up an experiment with three mirrors.

Problem is, he doesn't need three mirrors for this experiment. But he does need three if he wants to show that the universe is based on a trinitarian concept of God.

Join me, Mark Scarbrough, as we look at one of the more surprising moments in PARADISO: the call for scientific experimentation (perhaps to prove a theological point).
