and representations of such tablets have been found in eighth-century BC
reliefs from Western Asia.24 They served for memoranda of all sorts –
ephemeral and occasional writing, like school notes and exercises, sketches
of compositions, bills and accounts.
The root Plato uses for ‘‘seal’’ is s¯eme-, which means ‘‘sign’’ or ‘‘a mark by
which something is known’’; it has several other more restricted meanings
related to the basic one, like a ‘‘signal’’ as in battle, or a ‘‘badge.’’25 It is
significant, it seems to me, how emphatic Plato is about the ‘‘sign’’-nature
of his metaphor, for he repeats the idea three times in three words: the
phrase translated ‘‘as we might stamp the impression of a seal ring’’ is in
Greek ‘‘ho¯sper daktylion s¯emeia ens¯emainomenous.’’ So the ‘‘seal in wax’’ is
basically a model of inscription or incising, as writing is incised upon a clay
or wax or stone surface. Moreover, the forms incised symbolize informa-
tion and thus are representations that serve a cognitive purpose, as do the
representations of words, whether by phoneme or syllable or unit of sense,
used in writing systems. In other words, to borrow some terms from the
cognitive psychologists, the ‘‘representation’’ in memory is ‘‘verbal’’ rather
than ‘‘pictorial’’ in nature.
The underlying implication of the metaphor of the seal in wax receives
one of its fullest expressions in Cicero’s De oratore, one of the major
vehicles through which the image came to later writers like Quintilian,
St. Augustine, Martianus Capella, and others. Later still, writers of the
scholastic Middle Ages found it anew in the Rhetorica ad Herennium,
ascribed by them to Cicero, and in the Latin translations and commen-
taries on Aristotle’s De memoria that became available during the thirteenth
century.
In Book II of De oratore, Antonius discusses with his friends the value of
memory training. He recounts how Simonides first discovered the princi-
ples of the mnemonic technique of placing images (imagines) in an orderly
set of architectural backgrounds (loci) in his memory because one day he
had just left a banquet hall when the roof collapsed on it, killing all who
were still there. He was able to reconstruct the guest list by recalling the
location of each person’s seat (sedes) at the table. Antonius goes on to say
26

that sight is the keenest of all our senses (sensus vivendi).26 Therefore,
perception received orally or by the other senses, or objects conceived
through thought alone, ‘‘can be most easily retained in the mind if they
are also conveyed to our minds by the mediation of the eyes.’’ Of course,
many things and events are of such a nature that we either have not seen or
cannot see what we wish to remember. In these cases, we should make them
visible by marking them with a sort of image or figure (quasi et imago et
figura).
These mental images, the ancients say, are sort of figures and similitudes.
The qualification is crucially important, for reasons well defined in modern
philosophical discussions of the nature of mental images. Following sug-
gestions of Wittgenstein, J. T. E. Richardson defines the representational
aspect of mental images functionally rather than mimetically. What defines
a mental image is not its pictorial qualities but whether its user understands
it to represent a certain thing. As J. A. Fodor has written of this same
subject, if asked to make a picture of a tiger I can paint a realistic portrait or
I can draw a stick figure, but in both cases I understand the result to
represent a tiger. ‘‘My images . . . connect with my intentions . . . I take
them as tiger-pictures for the purposes of whatever task I have in mind.’’27
The mental image which an individual makes need have little to do with
objective reality. Donald Norman reports on experiments with mental
imaging which he has conducted, and notes that most people, when
asked what city in North America is most directly across the Atlantic
Ocean from Madrid, Spain, construct a mental map on which most of
them say they ‘‘see’’ that Madrid is somewhere south of Washington, DC –
Richmond, Virginia, or perhaps Cape Hatteras. In like manner, most place
London on a line with Boston, and Paris with New York. A glance at a map
shows that this mental image is clearly wrong as an accurate representation
of the latitudinal relationship of these cities.28 For my part, I cling to my
‘‘wrong’’ images no matter how often I am corrected, because the image
functions cognitively for me not as a terrestrial map but as a cultural one.
I know that Madrid is ‘‘south’’ in Europe, and so I place it ‘‘south’’ in the
United States. Paris, London, and New York (lined up in a row in my
mental image) are aligned because they are all three cultural capitals. Given
its cognitive function for me, my cultural map is perfectly ‘‘correct,’’ and
I am right not to change it.
A functional definition understands the words ‘‘representation’’ and
‘‘image’’ in ways that I think are essentially compatible with ancient under-
standing embodied in words like s¯eme- and its derivatives, and in the
subsequent, continuous development of the metaphor of mental image

as writing. The likeness between the two terms of the metaphor is one of
cognition (as a word ‘‘represents’’ a concept) rather than the replication of
form. The structures which memory stores are not actual little pictures, but
are quasi-pictures, ‘‘representations’’ in the sense that the information
stored causes a change in the brain that encodes (the modern word) or
molds (the ancient one) it in a certain way and in a particular ‘‘place’’ in the
brain. This ‘‘sort-of’’ image is then used as the basis for thought by a process
(intellection) which understands it to be a configuration standing in a
certain relationship to something else – a ‘‘representation’’ in the cogni-
tively functional sense, as writing represents language.
Such a distinction between objective and functional representation
probably lies behind Aristotle’s analysis, in 450b 11–20 of De memoria, of
how a memory-image, which is ‘‘like an imprint or drawing in us,’’ can also
cause us to remember ‘‘what is not present.’’ He likens the memory-
drawing to a painted panel: ‘‘the figure drawn on a panel is both a figure
and a copy . . . And one can contemplate it both as a figure [zo¯on] and as a
copy [eiko¯n].’’ As a figure or picture it is ‘‘an object of contemplation
[th¯eor¯ema] or an image [phantasma]. But, in so far as it is of another
thing, it is a sort of copy [oion eikon] and a reminder [mn¯emoneuma].’’29
If, for example, there should pop into my mind a delightful composition of
the letters and numbers ‘‘Psalms 23:1,’’ I may regard it simply as a picture
that I can think about for its own sake. But if this ‘‘picture’’ also reminds m
e
of the words, ‘‘The Lord is my shepherd; I shall not want,’’ then it is a signal
or cue for remembering, and it ‘‘stands for’’ those words as a ‘‘sort-of copy’’
of them.
The distinction between ‘‘figure’’ and ‘‘copy’’ continued to be emphasized
in both Arabic and scholastic comment upon Aristotle’s text. Avicenna and
Averroe¨s address it as the distinction between regarding an image as a
picture or as a portrait. What is involved in remembering is the association
and recollection of previously impressed material when the original is no
longer present to us. If the object should become actually present to our
senses again and we can compare our mental image to it for accuracy, we are
engaged in a process of recognizing rather than of remembering or recollect-
ing. We might, in such a situation, be momentarily embarrassed that our
mental stick-figure bore so little resemblance to the actual lineaments of the
tiger we see before us. At such a moment, we are regarding our mental image
as a ‘‘picture,’ to be judged as good or bad according to whether it presents a
recognizable likeness of the original we see. As portrait, however, the mental
image calls to mind someone who, by definition, is not present; its function
in such circumstances is to remind or recollect to us its original. As picture,
28

the formal characteristics of the image itself are all-important; as portrait, its
recollective or heuristic function is paramount to everything else.30
The distinction which philosophers of language are now making
between ‘‘formal’’ and ‘‘functional’’ views of linguistic representation is
useful also as a modern restatement of the ancient distinction between
‘‘philosophical’’ and ‘‘rhetorical’’ concerns. 31 The extreme idealist or for-
malist thinks of language in terms of how completely it represents the tiger,
and since it can never fully get that right, would rather lapse into silence
than speak. The rhetorician or pragmatist, having to speak, accepts that
words are all more or less in the nature of crude stick-figures, but can be
used meaningfully so long as speaker and audience share a common
cultural and civic bond, whether that of civitas Romana or civitas Dei, a
bond forged by the memories of people and their texts. Where classical and
medieval rhetorical pragmatism diverges from modern, I think, is in
assigning a crucial role to a notion of common memory, accessed by an
individual through education, which acts to ‘‘complete’’ uninformed indi-
vidual experience. This notion is basic to Aristotle’s view of politics as the
life of the individual completed in society. Such assumptions put the civic
bond on a historically continuous basis, and make the notion of shared
meaning less arbitrary and merely occasional than most modern ‘‘func-
tional’’ theories of language tend to do.
If we, in Paul Ricoeur’s phrase, unpack the metaphor incorporated in
the scholastic dictum ‘‘veritas est adaequatio verbi et rei,’’32 we find that it
embodies what is basically a rhetorical view of the representational relation-
ship between word and thing (and we must always remember that the Latin
word res is not confined to objects of our senses but includes notions,
opinions, and feelings) – that is, a view based on the principle of deco-
rum. 33 Adaequatio is a word of relationship, ‘‘adjustment,’’ ‘‘fitting’’ a word
to what one wants to say. The prefix is crucial to its meaning, not a dead
metaphor. Aequatio and its adjective, aequalis, convey the notion of iter-
ation, ‘‘equal,’’ identity of a formal, quantifiable sort. But in this dictum,
truth contained in words is always ad-aequatio, getting towards identity but
never achieving it. Although adaequatio is sometimes applied even by
medieval logicians to the sorts of mathematical identities one derives
from truth-tables, that is a specialized use of the word which ignores its
root metaphor. Aequatio conceptually admits only of true or false; adae-
quatio, being a matter of relationship and not identity, admits of many
grades and degrees of approximation. Aequalitas is an absolute and neces-
sary state of affairs; adaequatio, being a matter of more-or-less, requires
human judgment. Adaequatio is a likeness between two non-identities,

and it thus has more in common with a metaphor or a heuristic use of
modelling than with an equal sign. 34
Partialness is also a characteristic of memory. This is true not only
because memory and recollection proceed by means of imagines rerum
rather than the things-themselves, but because a part of the original
experience is inevitably lost or ‘‘forgotten’’ when the memory impresses
the imago of a res. This position is common to both Aristotelians and
Platonists, those who believe the mind stores and makes use only of
phantasmata derived from the sensory mediation of ‘‘objects,’’ and those
who believe the memory also has been truly stamped by divine Ideas, which
humans have ‘‘forgotten’’ because of original sin or simply in the act of
birth. Albertus Magnus writes that since recollection is of past experience,
there is a ‘‘break’’ between the original action of memory that impresses the
sensory image and its recollection. This break means that the original
experience itself is lost, wholly or in part. Recollection thus becomes a
reconstructive act, analogous to reading letters that ‘‘stand for’’ sounds
(voces) that ‘‘represent’’ things in a more-or-less adequate, fitting way.35
This is also to say that human understanding occurs in an occasional
setting; it is not universally and eternally fixed. By their very nature signs
are sensible, practical, worldly, belong to the traditional realm of rhetoric
and must be understood within its procedures, most particularly the
process of decorum, of fitting a word to a thing in terms that an audience
will understand. 36
Without getting too far into the intricacies of medieval signification
theory, upon which much excellent work has been done, 37 I would stress
that the assumption behind all the theory is that signs can be meaningfully
judged and interpreted. Because it recalls signs, reminiscence is an act of
interpretation, inference, investigation, and reconstruction, an act like
reading. But in pre-modern thought, signs only have meaning as they
refer to something else. A pre-modern memory phantasm is not a picture
of what it represents, but neither is it ‘‘language,’’ as modern philosophers
use this term, for it has no inherent ‘‘grammar,’’ no necessary structure of its
own. 38 The task of the recollector who is composing (and, as we will see,
recollection is commonly described as an act of composition, a gathering-
up into a place) is to select the most fitting and adequate words to adapt
what is in his memory-store to the present occasion. Language is shaped to
thought, or, as Chaucer wrote, ‘‘The wordes moote be cosyn to the dede’’

understanding, ‘‘the word which shines within’’ illuminated by grace, and
which then must find expression in words ‘‘spoken without’’ in human
tongues conditioned by particular times and places. Because of its very
nature, the relationship between the inner truth and its human expression
in language will be inexact, unequal; like the pagan orator, the Christian
will also have to seek a decorum, a mean or ‘‘adequacy’’ or plane of
congruence between these two inequivalencies. 39
Most pre-modern writers thought of knowledge as a collection of truths
awaiting expression in human languages, and fitted, as appropriate, to
various occasions. These truths are general but can never, with the excep-
tion of a limited set of mathematical axioms, be universally or singly
expressed.40 Ethical truths especially are expressed not singly but ‘‘copi-
ously.’’ When one examines a typical entry in a medieval florilegium
one finds not generalized definitions, together with illustrative citations,
as in a modern dictionary. One finds under a heading such as justicia
dozens of dicta and often facta or exemplary stories as well, each of which
is a definition, or, more precisely, a way-of-having-said (dictum) ‘‘justice.’’
Copiousness, like decorum, is an essential part of a rhetorical understand-
ing of the nature of human speech; indeed, copiousness and decorum are in
a relationship analogous to symbiosis. The memory of an orator is like a
storehouse of inventoried topics that ideally would contain all previous
ways-of-saying ethical truths like ‘‘justice,’’ ‘‘fortitude,’’ ‘‘temperance,’’
from which he draws in order to fit words to yet another occasion,
requiring another way-of-saying. But this storehouse should be thought
of as a set of bins that are empty when we are born and get filled up with a
lot of ‘‘coins’’ or ‘‘flowers’’ or ‘‘nectar,’’ whose aggregate is a meaningful if
only partial ‘‘speaking’’ of ‘‘justice,’’ or whatever. And each ‘‘speaking’’ of
