摘要:The challenge of thick character consists in explaining the apparent fact that one object can be charactered in many ways. If we assume a trope bundle theory, we ought to answer in turn the two following questions: (P1) What are the requirements on a trope bundle theory if it is to adequately account for thick-character?; (P2) Is a trope bundle theory that meets those requirements preferable to rival theories? In order to address the above questions, the paper proceeds as follows. In the first section I cover two preliminary matters: I introduce the concept of thick-character and distinguish it from other related concepts. Then, I sketch several leading accounts of character and situate bundle theory among them. Also, I pick up (Q1) and argue that there are three requirements on a trope bundle theory if it is to adequately account for thick-character. Lastly, in the third section I pick up (Q2) and argue that the requirements spell trouble for trope bundle theory. This trouble, I argue, indicates that trope bundle theory—and hence bundle theory simpliciter—fails to better its chief rival, substance-attribute theory.
