1. Attractive memory: attracts species to itself from outside to nourish its own special intrinsic act of remembering which cannot proceed unless it attracts prergrine species with its innate goodness, with the intellect and with the will. Now the intellect and the will cannot acquire any species unless memory naturally participates in acquiring them, because the intellect on its own cannot understand, nor can the will desire on its own, any species not remembered by the memory.
Nine Functions of Memory
Blessed Raymond Lull
2. Receptive memory: through its recollective part, receptive memory receives, in its own innate co-essential or general recollectible part, peregrine species acquired from the outside by the intellect and will to which memory is joined. These species are illuminated by things that the senses, imagination and intellect perceive while memory receives them in different ways with goodness, greatness etc.
3. Conservative memory: memory conserves and governs species in its innate general recollectible part which endures with its own natural goodness, greatness and power. The governance of memory relies upon the ebb and flow of memory's intrinsic and extrinsic habits, without which nothing can be conserved. As human life cannot be governed without food, so we need to seek out books, pictures, stories, sculptures and other figures.
4. Multiplicative memory: in its own intrinsic scientific habit, memory reproduces the things it has memorized . It multiplies, or reproduces objects through signs, first by making syllables, then words and statements as multiplication begins with units and develops into plurality. And then it multiplies statements to form syllogisms and through syllogisms, the memory develops its scientific habit. Now if someone wants to remember a woman's name, for instance "Maria", and already knows another called "Martha", remembering "Mar" helps to remember the rest of the name "Maria".
5. Discursive memory: In its discourse through peregrine species the memory remembers one species at one time and another species at another time; these species can be higher or lower, good or bad, similar or dissimilar and differently received with supposition, belief, understanding, love or hate. Now the memory does all this to store the material in which it seeks the repose of its intrinsic act of remembering.
6. Significative memory: receives meanings conveyed to it, for instance: goodness signifies a good subject and greatness a great one, and a good subject signifies good action; a father signifies his son, a drunken woman signifies lust, and the terms of a question signify its solution. And thus, things are signified by signs.
7. Restorative memory: memory receives species as input and restores them as output. In attracting the species it receives, memory relies upon the intellect and the will to entrust species to it for safekeeping so they can later ask memory's storekeeper to give them back. Now the intellect and the will do this in order to deal with the past objectively, not subjectively, because past things are real but subjective things are not; and so the Art requires that the intellect and the will seek out the species acquired in the past. The retrieval of species from the past retraces the process through which they were initially entered and stored in memory by reason of goodness, or some other reason, because memory cannot restore data without retracing the path through which it was entered, and this path leads through the senses, the imagination, the intellect, the will, etc.
8. Determinative memory: memory determines - or defines - its acts within the scope of the acts of intellect and will so its remembering is accompanied by understanding and will, or love.
9. Complexionative memory: the elemental complexion of memory is cold and dry, but only accidentally so on account of the body to which it is joined.
