Do thoughts have parts? Peter Abelard: Yes! Alberic of Paris: No!

Abstract

ABSTRACT Spoken sentences have parts. Therefore they take time to speak. For instance, when you say, ‘Socrates is running’, you begin by uttering the subject term Socrates, before carrying on to the predicate. But are the corresponding thoughts also composite? And are such thoughts extended across time, like their spoken counterparts? Peter Abelard gave an affirmative response to both questions. Alberic of Paris denied the first and, as a corollary, denied the second. Here, I first set out Abelard’s account. I then present a series of arguments against Abelard, reconstructed from (sometimes fragmentary) manuscripts associated with Alberic’s school. I conclude with an observation about present philosophy of language: this twelfth-century debate points to some undefended (and largely unstated) assumptions common to more recent thinking about propositions.
