                           ON MEMORY AND REMINISCENCE



                                  by Aristotle



                           translated by J。 I。 Beare



                                1







  WE have; in the next place; to treat of Memory and Remembering;



considering its nature; its cause; and the part of the soul to which



this experience; as well as that of Recollecting; belongs。 For the



persons who possess a retentive memory are not identical with those



who excel in power of recollection; indeed; as a rule; slow people



have a good memory; whereas those who are quick…witted and clever



are better at recollecting。



  We must first form a true conception of these objects of memory; a



point on which mistakes are often made。 Now to remember the future



is not possible; but this is an object of opinion or expectation



(and indeed there might be actually a science of expectation; like



that of divination; in which some believe); nor is there memory of the



present; but only sense…perception。 For by the latter we know not



the future; nor the past; but the present only。 But memory relates



to the past。 No one would say that he remembers the present; when it



is present; e。g。 a given white object at the moment when he sees it;



nor would one say that he remembers an object of scientific



contemplation at the moment when he is actually contemplating it;



and has it full before his mind;…of the former he would say only



that he perceives it; of the latter only that he knows it。 But when



one has scientific knowledge; or perception; apart from the



actualizations of the faculty concerned; he thus 'remembers' (that the



angles of a triangle are together equal to two right angles); as to



the former; that he learned it; or thought it out for himself; as to



the latter; that he heard; or saw; it; or had some such sensible



experience of it。 For whenever one exercises the faculty of



remembering; he must say within himself; 'I formerly heard (or



otherwise perceived) this;' or 'I formerly had this thought'。



  Memory is; therefore; neither Perception nor Conception; but a state



or affection of one of these; conditioned by lapse of time。 As already



observed; there is no such thing as memory of the present while



present; for the present is object only of perception; and the future;



of expectation; but the object of memory is the past。 All memory;



therefore; implies a time elapsed; consequently only those animals



which perceive time remember; and the organ whereby they perceive time



is also that whereby they remember。



  The subject of 'presentation' has been already considered in our



work On the Soul。 Without a presentation intellectual activity is



impossible。 For there is in such activity an incidental affection



identical with one also incidental in geometrical demonstrations。



For in the latter case; though we do not for the purpose of the



proof make any use of the fact that the quantity in the triangle



(for example; which we have drawn) is determinate; we nevertheless



draw it determinate in quantity。 So likewise when one exerts the



intellect (e。g。 on the subject of first principles); although the



object may not be quantitative; one envisages it as quantitative;



though he thinks it in abstraction from quantity; while; on the



other hand; if the object of the intellect is essentially of the class



of things that are quantitative; but indeterminate; one envisages it



as if it had determinate quantity; though subsequently; in thinking



it; he abstracts from its determinateness。 Why we cannot exercise



the intellect on any object absolutely apart from the continuous; or



apply it even to non…temporal things unless in connexion with time; is



another question。 Now; one must cognize magnitude and motion by



means of the same faculty by which one cognizes time (i。e。 by that



which is also the faculty of memory); and the presentation (involved



in such cognition) is an affection of the sensus communis; whence this



follows; viz。 that the cognition of these objects (magnitude; motion



time) is effected by the (said sensus communis; i。e。 the) primary



faculty of perception。 Accordingly; memory (not merely of sensible;



but) even of intellectual objects involves a presentation: hence we



may conclude that it belongs to the faculty of intelligence only



incidentally; while directly and essentially it belongs to the primary



faculty of sense…perception。



  Hence not only human beings and the beings which possess opinion



or intelligence; but also certain other animals; possess memory。 If



memory were a function of (pure) intellect; it would not have been



as it is an attribute of many of the lower animals; but probably; in



that case; no mortal beings would have had memory; since; even as



the case stands; it is not an attribute of them all; just because



all have not the faculty of perceiving time。 Whenever one actually



remembers having seen or heard; or learned; something; he includes



in this act (as we have already observed) the consciousness of



'formerly'; and the distinction of 'former' and 'latter' is a



distinction in time。



  Accordingly if asked; of which among the parts of the soul memory is



a function; we reply: manifestly of that part to which



'presentation' appertains; and all objects capable of being



presented (viz。 aistheta) are immediately and properly objects of



memory; while those (viz。 noeta) which necessarily involve (but only



involve) presentation are objects of memory incidentally。



  One might ask how it is possible that though the affection (the



presentation) alone is present; and the (related) fact absent; the



latter…that which is not present…is remembered。 (The question arises);



because it is clear that we must conceive that which is generated



through sense…perception in the sentient soul; and in the part of



the body which is its seat…viz。 that affection the state whereof we



call memory…to be some such thing as a picture。 The process of



movement (sensory stimulation) involved the act of perception stamps



in; as it were; a sort of impression of the percept; just as persons



do who make an impression with a seal。 This explains why; in those who



are strongly moved owing to passion; or time of life; no mnemonic



impression is formed; just as no impression would be formed if the



movement of the seal were to impinge on running water; while there are



others in whom; owing to the receiving surface being frayed; as



happens to (the stucco on) old (chamber) walls; or owing to the



hardness of the receiving surface; the requisite impression is not



implanted at all。 Hence both very young and very old persons are



defective in memory; they are in a state of flux; the former because



of their growth; the latter; owing to their decay。 In like manner;



also; both those who are too quick and those who are too slow have bad



memories。 The former are too soft; the latter too hard (in the texture



of their receiving organs); so that in the case of the former the



presented image (though imprinted) does not remain in the soul;



while on the latter it is not imprinted at all。



  But then; if this truly describes what happens in the genesis of



memory; (the question stated above arises:) when one remembers; is



it this impressed affection that he remembers; or is it the



objective thing from which this was derived? If the former; it would



follow that we remember nothing which is absent; if the latter; how is



it possible that; though perceiving directly only the impression; we



remember that absent thing which we do not perceive? Granted that



there is in us something like an impression or picture; why should the



perception of the mere impression be memory of something else; instead
