Abstract
The principate of Augustus coincided with a surge of interest in the short Aristotelian treatise which we now entitle Categories, contributing to its later installation at the outset of the philosophical curriculum and its traditional function as an introduction to logic. Thanks in part to remarks made by Plutarch and Porphyry , the origin of this interest has often been traced to Andronicus of Rhodes: his catalogue and publication of the Aristotelian corpus began with the Categories and may have drawn fresh attention to a previously obscure treatise. But the later Neoplatonic sources name several other philosophers who also discussed the Categories and played an important role in crafting its interpretation during the first centuries of our era. For example, the Neoplatonist Simplicius discusses the views of Stoics and Platonists who questioned the Categories' value as a treatment of grammar or ontology, while others defended its usefulness as an introduction to logic. These early debates, as these later sources suggest, exercised a lasting influence on the shape of subsequent philosophy and philosophical education within and beyond the Aristotelian tradition
