Steven Campbell-Harris reminds us that some of our attempts at reasoning can miss something.  If a child, or an adult, makes a declarative statement that they claim is true and then attempts to provide reasons or grounds for why that is so, there is a third thing that is needed, the warrant, which is often left as an unstated assumption about why the grounds justify the claim.  How can philosophical enquiry help with getting us out of this lazy way of expressing our ideas?
