It sheds no light on what it is your trying to convey by your use of 'necessity'. And the operator □ is already taken and is not a truth-functional operator so reusing it for something else is just plain stupid. And snipping my question doesn't make it go away: Can you give an example where (a) hold true but where (b) does not. An example from ordinary English is fine. a) Q is a consequence of P b) Q is a necessary consequence of P. If you can't, your use of the term 'necessary' serves absolutely no purpose.
