Although every “acquired species” comes through imagination, Bonaventure creates another category of species, called innate species, that are imprinted directly on the memory. Bonaventure writes, “Memory has to be informed not only from the outside by phantasms but also from the above, by receiving and having in itself simple forms that cannot enter through the doors of the senses, nor through sensible phantasms.”
