Sellars: You can’t understand either of these kinds of oughts without understanding both. In particular, if you try to do everything with ought-to-do’s:
- One would fall into a kind of Cartesianism: we’d need to think of linguistic episodes as essentially the sort of thing brought about by an agent whose conceptualizing is not linguistic.
- We’d be precluded from explaining what it means to have concepts in terms of the rules of the language. Ought to do’s have the form of “in circumstances , do ” - what language are and stated in? Regress of rules without ought-to-be’s.
This is important because natural way to think of rules is exlusively in terms of Ought to Do (Sellars himself advocated this earlier: “A rule is always a rule for doing something”).
There is also an analogous distinction involving permission, rather than obligation.
This lets us avoid the rule obeying regress.
This distinction also can be used to avoid paradoxes of “ought” for things we don’t have control over, e.g. I ought to believe such-and-such but I do not have control over my beliefs. Only ought-to-do’s presuppose that one has agency to conform, while ought-to-be’s do not.1
