Morality and a Scaffolding of Facts

In reply to Michael Campbell, I reformulate my questions of Raimond Gaita, avoiding the expression “form of life”. I examine what might remove the need for my questions, before taking up Campbell's line of thought about what he calls the “inwardness” of moral concepts. Campbell helps to clarify the picture of moral concepts advanced by Wittgensteinian moral philosophers. But at a general level, the picture remains unclear where a grammar meets its scaffolding of facts. Some may find this unproblematic, and indeed unavoidable. But I remain unsure of this, and hope to provide at least a useful caution.
