The previous objections to the Unlearning Problem Argument made the points, first, that negative evidence does exist in the pld (in the form of regularities both in others' language use and in how others react to children's own productions), and second, that children (and other animals) seem very good at exploiting this kind of information for the purposes of learning about their world.
White Regularity is congruent to all other forms of regularity i.e. Black, Brown, Etc etc.
If R is the relation of spatio-temporal contiguity, then the ideas are joined to form a judgment of regularity, a causal judgment.
Armstrong argues against all forms of the regularity theory; laws, on his view, are necessary connections of universals that neither depend nor supervene on the course of worldly events but determine, restrict, and govern those events.
Put very generally, the various forms of the regularity theory all count laws, if they count them at all, as contingent generalizations or mere descriptions of the events to which they apply: "All there is in the world is a vast mosaic of local matters of particular fact, just one little thing and then another," as David Lewis put this view (1986, ix).
The simple notion behind the origination of NIRT is to relax this function to more general - though still monotonically increasing - form, without the degree of regularity characteristic of the sigmoid-shapes that result from the use of the logistic or probit link functions.
And β-folded, the second most quantity in the secondary structures of proteins, has the form of pleated sheet with regularity.
But this does not lead Hume to hold that since we can't infallibly perceive that some succession is an instance of a regularity, we cannot form the concept of causality in terms of regularity.
