How do I solve the Magic Lantern puzzle in the Boston Underground?

Solution 1:

I literally just did this!

The clues are in a letter you find, and they are as follows:

UNDER ALL CIRCUMSTANCE-OBEY AND BALANCE THE MORAL LAW
THE GLOBE OVER
BE IT CHRISTIANITY OF THE WEST
BUDDHISM OF THE EAST

The BALANCE is represented by the scales of justice. The globe is the GLOBE, obviously. The cross symbolizes CHRISTIANITY, and the steering wheel is a symbol for BUDDHISM.

Based on the last two lines, Christianity is of the West, so the cross goes on the left. Buddhism is of the East, so the wheel goes to the right.

Then, for the first two lines, the moral law is to be obeyed under all circumstances, so the scales are on the bottom. Furthermore, the moral law must be obeyed all over the globe, so the globe is on top.
