Expressing an intention or volition is not the same as (self-)ascribing, an intention or volition, nor are such expressions descriptions of intentions or predictions of action.  Expressions of intention are always first-personal in form and essentially tied to motivational force.  Sellars reserves ‘shall’ to serve as an operator-like marker of intention expressions, and this convention will be observed here as well.  Sellars recognizes two forms of ‘shall’-statements: ‘I shall do A’ and ‘It shall be the case that p’.  ‘Shall be’s’ must ultimately imply ‘shall’s with direct implications for action, even if they are highly conditioned on other circumstances.
