Non-Humean accounts of lawhood are said to founder on the Inference Problem, which is the problem of saying how laws that go beyond the regularities can entail the regularities. I argue that the Inference Problem has a simple solution – the Axiomatic Solution – on which the non-Humean only needs to outfit her laws with a law-to-regularity axiom. There is a remaining Epistemic Bulge, as to why one should believe that the posit-so-axiomatized is to be found in nature, but the non-Humean can flatten the bulge. Lawhood serves as a case study of how fundamental posits can do their business.

In Ordinary Objects, Thomasson pursues an integrated conception of ontology and metaontology. In ontology, she defends the existence of shoes, ships, and other ordinary objects. In metaontology, she defends a deflationary view of ontological inquiry, designed to suck the air out of arguments against ordinary objects. The result is an elegant and insightful defense of a common sense worldview. I am sympathetic—in spirit if not always in letter—with Thomasson’s ontology. But I am skeptical of her deflationary metaontology.

The skeptic says that “knowledge” is an absolute term, whereas the contextualist says that “knowledge” is a relationally absolute term. Which is the better hypothesis about “knowledge”? And what implications do these hypotheses about “knowledge” have for knowledge? I argue that the skeptic has the better hypothesis about “knowledge”, but that both hypotheses about “knowledge” have deeply anti-skeptical implications for knowledge, since both presuppose our capacity for epistemically salient discrimination.
