HYPOTHETICAL IMPERATIVE II
For instance, if you want to begin collecting art, then your ability to collect good art will be dependent or conditional on your ability to recognize good art.
It is therefore imperative that you learn something about art so that you can tell the good from the bad. And the hypothetical command of reason in this case would be: “If you want to build a good collection of art (the hypothetical) then learn about art (the imperative).
Thus learning about art is good, but it is hypothetical because it is a means to something else, namely acquiring a good collection.
