Why the new missing explanation argument fails, too

The so-called missing explanation argument, put forward by Mark Johnston in the late 80's purported to show that our ordinary concepts of secondary qualities such as the colours cannot be response-dependent. A number of flaws were soon found in the argument. Partly in response to the criticism directed at the original argument, Johnston presented a new version in 1998. In this paper I show that the new version fails, too, for a simple reason: the kind of explanation which Johnston claims to be incompatible with a response-dependent account of the relevant concept is not an empirical explanation at all, but merely looks like one because of certain factors in Johnston's stage- setting for the argument.
