TEST 1: MAKING FALSE PROMISES I
Could the rule ‘it is okay to break a promise,’ or ‘it is okay to make a false promise’ be universalized?
If so, that is, if it would be okay for everyone to make promises which they don’t intend to keep, then making false promises would fit the categorical imperative and so would be morally acceptable.
But can making false promises be universalized? To answer this we must ask what would happen, or what the consequences would be, of everyone making promises which they do not intend to keep.
