Abstract for “Singular Thoughts and De Re Attitude Reports” – James Openshaw

What does the truth of a de re attitude ascription require of its subject? What is required of a thinker in order that she entertain a singular thought? I offer a semantic framework which enables us to answer, to the first question, that it is a context-dependent matter, and to the second question that the thinker must satisfy some invariant ‘acquaintance’ constraint. The upshot is that the principal argument against philosophically interesting requirements on singular thought, which has dominated the literature in recent decades, is no good.
