I think this section ought to begin to point us to once and for all tune in on the role of memory as an important part of Epicurean theory;
QuoteAs for memory, it plays a central role for what a person thinks, as it is repeatedly mentioned by Epicurus, whether in reference to remembering the main tenets of Epicurean doctrine49, or remembering the προλήψεις or preconceptions a person naturally has in order to subsequently have the right beliefs and keep away from confusion and error50. Thus, for Epicurus, sense-perception alone does not provide knowledge of reality but rather the fundamental information in order to reach knowledge. For, crucially, the form of reasoning Epicurus has in mind is based on sense-data (Her. 32), as is the notion of memory he is interested in. It is a deviation from sense-data which brings on error and false beliefs51
