 None of the foregoing considerations   in favor of the fruitfulness of distinguishing assertoric content and ingredient sense is beyond controversy. One might resist (critics include Everett 2005, pp. 125–38; King 2007, pp. 168–196; Shieh 2001, pp. 379–80; Soames 2005, pp. 321–3n.; defenders include Ninian 2012; Stalnaker 2014, pp. 23–24; Yalcin 2014). But the question of whether the foregoing descriptivist line of thinking is sound, or whether any descriptivist line is sound, is less important here than the question of what rides on the answer for rigidity.
