Question

What does the respect formulation of the categorical imperative command?

Answer 1

I'm not sure which formulation is the 'respect formulation', but the three formulations of the categorical imperative are:

1. Always act according to a moral principle which you would desire to be a universal law.

2. Always treat persons, whether yourself or others, as ends in themselves (never as means to an end).

3. The will of every moral agent can be conceived as a universal legislature.

Answer 2

Nothing; The categorical imperative falls apart because it is contingent on how one describes an action, which makes it reconcilable with virtually any action..
