Supposition Theory - Ampliation

Ampliation

When I say No cups are made of lead, cups supposits for all the cups that exist. But if I say Some cups were made of lead in Roman times, cups cannot just be suppositing for all the cups that exist, but for cups in the past as well. Here I am expanding the normal supposition of the terms I use. Peter of Spain says "Ampliation is the extension of a common term from a lesser supposition to a greater one." In practice, if I speak of the past, or the future, or make a modal claim, the terms I use get ampliated to supposit for past things, future things, or possible things, rather than their usual supposition for present actual things. Thus, ampliation becomes the medieval theory for explaining modal and tense logics within the theory of supposition.
