G. E.R. LLOYD
The debates on the definition, status, and methods of the medical téxvn
that took place in the fifth and fourth centuries BC offer us a remarkable
opportunity to explore a whole range of issues.
In part these are sociological and concern the relationships between the various groups who laid
some claim to the title, iatpös, or who were involved, in practice, in one
or other aspect of one or other rival or complementary tradition of treating
the sick.
In part they also relate to epistemological and methodological
questions concerning the nature of a Téxvn, its defining characteristics, and
the type of knowledge it presupposes. Although I shall be concerned chiefly
with the second group, it would be foolish to attempt to deal with those
questions in isolation from those that come under the first heading. Certainly in many Hippocratic texts besides the three treatises I shall be using
as my principal evidence (On the Art, On Regimen in Acute Diseases, On
Ancient Medicine), there is a recurrent preoccupation not just with defining medicine and setting down its methods, but also with how the doctor
is to be distinguished from the layman, and again how from imposters,
charlatans, or doctors in name alone.
It is well known that apart from the medical writers represented in the
Hippocratic Corpus (themselves a highly heterogeneous set) several other
groups were also involved in healing the sick.
There were, for example,
the ‘midwives’ (naiaı) concerned, of course, with much more than that
conventional translation might suggest. Again, the collection, sale, and administration of drugs, especially herbal remedies, were chiefly the province
of those called pigotépot (root-cutters) and dappakonadaı (drug-sellers).
On occasion, as texts such as [Demosthenes] In Neaeram lix 55-56 confirm,
the women of the household went and bought drugs and administered them
Página 3
Ver en el PDF(se abre en una ventana nueva)themselves without, it seems, calling in an iatpés of any kind. There were
also those whose discourse on diagnosis and cure drew heavily on the categories of the divine and the supernatural; but again they can hardly be
treated as a single group, since there are important differences between on
the one hand the itinerant purifiers and sellers of charms and incantations
whom we hear about from Plato, for instance, as well as from On the Sacred Disease, and on the other those who practised temple medicine in the
increasingly well-established shrines of Asclepius and other healing gods or
heroes.
Now plurality of medical traditions is far from unique to classical Greece:
it can be paralleled in ancient Egypt and in ancient Babylonia to look no
further afield in ancient, let alone modern, societies.
But what is more
exceptional is the overt and explicit attacks by one group or another. The
point must not be exaggerated. As I have recently had occasion to stress
elsewhere, not every Greek group of healers attacks or criticises every other
one. Some of the relations between more or less clearly demarcated groups
are marked by a certain tolerance and a mutual, though not necessarily
symmetrical, respect. We do not find Hippocratic writers of any kind engaging in polemic with the midwives as a group, for instance, or with those
whom the author of On the Diseases of Women i 68 calls the women healers;
rather, as I tried to show in Science, Folklore and Ideology [Lloyd 1983a],
there is some cooperation between them. On the other hand, some of the
boundaries between one group and another were highly contested.
The
onslaught on the itinerant purifiers in On the Sacred Disease is the best
known example, but we should be careful not to assume that it was always
those represented in the Hippocratic Corpus who did the attacking (even
though much of our evidence comes from them). It is clear enough from
Aelius Aristides that, in the second century AD at least, temple medicine
often set itself apart from and indeed criticised other styles of healing; and
there are signs of that developing already much earlier in the fourth century
BC in the inscriptions from Epidaurus.
Quite why in Greek society there are these explicit attacks is, to be sure,
a highly complex and controversial question which I shall not attempt to
reopen here.
But that they existed is both clear enough and important.
Evidently, when some of the frontiers or boundaries were a veritable battlefield, it was not going to be enough for those within a particular group
to sit back and assume that sufficient raison d’étre for their style of activity came from the very existence of the group itself.
Self-justification
was the order of the day and many Hippocratic treatises revert to the
point, even when they are not devoted to it entirely (as On the Art is).
Of course, self-justification could take many forms. In some Hippocratic
-Tpt—arenit,
Página 4
Ver en el PDF(se abre en una ventana nueva)works (such as the Oath, Decorum, and especially Precepts) the writers
show themselves chiefly concerned with the moral respectability of their
fellow-iatpot.
Several of the deontological treatises are products of the
Hellenistic period, and Precepts
in particular shows clear signs of influence from Hellenistic epistemology.
Yet—whatever its date—it certainly
illustrates how methodological recommendations could be combined with
advice about bedside manner, about morality, about economic aspects of
medical practice, and so on. The author is as anxious about doctors getting
a bad name for themselves for ostentation, avarice, and lack of dıAavöpwrin,
as he is about their doing so through faulty medical practice.
Attacks on other healers sometimes involve the exposure of an entire
group with whom the author certainly does not identify himself, as when
On the Sacred Disease sets out to demonstrate the fraudulence of the purifiers. But the accusations of bad practice, even charlatanry, can also be
levelled at those whom you recognise—or others do—as your colleagues.
Often in the surgical treatises, for example, criticisms of bad surgical practices involve no more than an explanation of the real or assumed harmful
effects—whether or not supported by reference to firsthand experience.
But sometimes such accusations lead to more general discussions of the
principles that should underlie medical practice, and of medical method
as a whole.
Three treatises which can be used to illustrate both certain
shared concerns and certain differences of approach are On the Art, On
Regimen in Acute Diseases, and On Ancient Medicine. I shall begin with
the most theoretical of these, or rather with the one that is least secure
in its practical medical knowledge, the treatise On the Art.
As is well known, this is a sophistic type of demonstration-lecture (émíBetis) and it is possible that the author was no practitioner himself. But
from our point of view, that cannot be held to detract from the value
of the evidence the work provides on the type of question raised about
medicine as a Téxvn, the kind of challenge that was offered, and the nature
of some of the points used (whether or not from inside the ‘profession’) in
its defence. The treatise opens with some general remarks about those who
have ‘turned the abuse of the téxvau into a Téxvn in itself’, and who are
accused by the author of On the Art of being nasty, malicious, ignorant
individuals and indeed of lacking téxvn (i.e., of being dtexvor).
He says
it is up to others to defend other téxvat, though chapter 9 seems to suggest
a promise by the author himself to deal with some aspects of these. But his
chief concern in this Aóyos is the defence of inrpn.
Página 5
Ver en el PDF(se abre en una ventana nueva)The question this opening chapter immediately poses is whom the author
has in mind.
Who was in business to abuse the Téxvat or speak shamefully of them?
We have plenty of evidence of Plato’s eventually wanting to downgrade some of the téxval and he certainly had little good to
say about those who practised them as full-time professionals. In Gorgias
464b-466a there is a contrast between certain genuine Téxvav (including
latpıcr)) and their spurious ‘flattering’ counterparts, and again between a
Téxvn and mere épmerpia [465a]; Phaedrus 260e calls rhetoric no texvn but
an dtexvos Tp and furthermore contrasts the practice of medicine as
a Téxvn with its practice only as a knack and by experience [Tp.BR póvov
Kal épmerpig: 270b]. Moreover, in the passage of fundamental importance,
Philebus 55e-58a grades the téxvar according to their degree of exactness:
medicine, in particular, comes in the lowest category (along with music,
farming, navigation, and generalship) and below carpentry, which itself
comes below the mathematical téxvat (subdivided here into the impure,
mundane applied branches and the purer, philosophical inquiries).
But apart from the problems of dating (and it is difficult to think that
the author of On the Art 2, which concerns the relations between words and
things, was familiar with Platonic dialogues such as the Cratylus), it must
be thought unlikely for two main reasons that On the Art 1 was directed
at Plato.
First, the attackers envisaged in this treatise apparently reject.
the téxvat wholesale; whereas, in the dialogues cited above at least, Plato
is concerned to draw distinctions between superior and inferior Téxvar and
indeed rates any téxvn higher than a mere knack. Second, the author of On
the Art refers to those who bring shame on the arts and their discoveries and
abuse them, and this hardly fits the character of the mainly epistemological
objections raised by Plato against the less exact Téxvat.
Is it, then, some group of sophists who ‘turn the abuse of the Téxvat
into a rexvn’?
So far as our evidence concerning that highly amorphous
group goes, I do not believe that anyone can be made to fit the bill exactly.
Of course there were those, including Gorgias, who privileged the art of
rhetoric and wrote books called Téxvat dealing with that subject; and in
the Platonic dialogue, Gorgias is represented as claiming that rhetoric is
more powerful than all the other arts: it is he, not his brother who was
a doctor, who persuades people to take their medicine [Gorg. 456b]; and
he claims that in any assembly or gathering set up to choose a doctor,
he would win the contest, thanks to his skill in speaking, and defeat any
actual doctor. That would obviously involve the discomfiture, the loss of
face, the shame, of any doctor unfortunate enough to be so defeated. Many
Hippocratic texts make clear just how upset their authors would be likely
to be at the prospect of losing an argument with a layman on a medical
Página 6
Ver en el PDF(se abre en una ventana nueva)matter. Nevertheless the identification breaks down. Although the effect
of the Platonic Gorgias’ claim would be shaming, the Platonic Gorgias
himself says that rhetoric should not be used to detract from the 8d€a
(reputation) of doctors [Gorg. 457b]: rather his case is the positive one,
that rhetoric, used justly, should be admired, not the destructive one that
the other Téxvat should not be.
Is it, then, that the author of On the Art has simply invented the artabusers he attacks?
That too seems a difficult conclusion to draw, not
least because of the huge gaps in our evidence for fifth- and fourth-century
‘sophists’ of one kind or another. That the Hippocratic author overstates
his opponents’ position, especially perhaps as regards their motivations,
may well be the case.
But we have enough independent grounds in the
Hippocratic Corpus itself that radical challenges to the status of tyrpiKy
had been mounted, to allow us to say that, in this instance at least, On the
Art has—not just Aunt Sallys—but genuine opponents, even if we cannot
name them.
We shall consider the evidence from On Regimen in Acute
Diseases and On Ancient Medicine shortly; but in what are probably later
works too, such as Precepts 9, there are signs of concern to defend medicine
against detractors and to show that it is a rexvn. That may be as far as it
is wise for us to go: yet even if the idea of a group of sophists attacking the
arts in general were a mere fiction, a figment of this author’s imagination,
it has one interesting implication nevertheless. Even if he had no such real
opponents, he has himself implicitly raised the very issue he accuses them of
pressing. They should not abuse the téxvat nor disparage their discoveries.
But this, of course, by implication poses the questions: What discoveries?,
and How secure are the claims of the Téxvat to be Téxvat? These issues are
most pertinent in a period when claims for new inventions, for founding new
inquiries and for innovating in existing ones, were all the rage. Moreover,
these issues once raised, this author’s defence of the arts in general is both
thin and indiscriminate: ‘it seems to me that in general there is no Téxvn
that does not exist’, the gist of his argument being that what can be seen
and recognised exists, and what cannot, does not.
What the author has to say on medicine in particular begins in chapter 3, and is marked by a certain self-consciousness in style. Thus, he will
begin his demonstration or exposition (dmd68etéts) of the Téxvn of medicine
with a definition (cf. dptedpar). This definition comes in two main parts:
(1) the complete removal of the sufferings of the sick, together with the
alleviation of the violences of diseases; and (2) the refusal to treat cases
‘where the disease has already won the mastery’, realising that in such
instances medicine is powerless.
One cannot help admiring the cunning
and bravura of this twofold statement.
On the one hand, the first part
Página 7
Ver en el PDF(se abre en una ventana nueva)claims the possibility of complete success and later chapters show that this
is no mere opening gesture of the hand. Chapter 9 subdivides diseases into
two main groups—broadly those with visible signs and those without—and
affirms of the former group that ‘in all cases the cures should be infallible, not because they are easy, but because they have been discovered’.
(Chapter 10 goes on to say that in the latter group too the Texvn should
not be at a loss.)
But the ‘heads I win, tails you lose’ character of his
original definition comes out when he deals with cases where the Téxvn is
not successful. There, the disease has already won the mastery and it would
be quite unfair to expect the Téxvn to be able to achieve a cure: indeed
it is perfectly right for doctors to refuse to treat such cases [cf. ch. 13]. So
where there are successes, they are proof of the power of the Téxvn: but no
failure, no inability to produce some alleviation, is allowed to count against
the art, since he has made it constitutive of medicine, in his definition, that
it refuses to deal with hopeless cases.
How far these extravagant claims, with their all-purpose fail-safe clause,
were likely to carry conviction—even with an audience at a sophistic EmldeıEs—we cannot know. Certainly the actual medical knowledge the author
displays is none too impressive.
Yet his attempt to distinguish between
the products of TExvn and those of mere chance, Téxn, in chapters 4-6,
does score some notable points. Some attribute the successes of medicine
merely to chance, he says in chapter 4, and some point out that people have
recovered even without calling a physician [ch. 5]. Now while he does not
rule out chance—but claims rather that good luck follows good treatment,
and bad luck, bad [ch. 4] —he mounts an argument in chapter 6 to suggest
that the spontaneous (TÓ autönaTov) is a null category. Everything that
happens, happens on account of something (81d T1).
Even if the patient
called in no doctor, his recovering from his complaint was due to doing
something or again to his not doing something [ch. 5], that is, to precisely
the means the doctor would have used, had he been called in. So the medical art is at work whenever there is a cure, whether or not the doctors are
in attendance—though chapter 6 ends with the further point that medicine
is real not just because it acts did Ti but also because its results can be
foretold.
The author of my second main text, On Regimen in Acute Diseases,
is altogether more knowledgeable about actual medical practice; but he
too shares some of the worries of On the Art.
The art as a whole, he
says in chapter 3, has a very bad name among laymen, to the point that
there is thought to be no inTpk at all. But here the problems arise not—
as in On the Art—because of malicious slanderers, but rather because
of the incompetence of, and especially the disagreements among, doctors
Página 8
Ver en el PDF(se abre en una ventana nueva)themselves. In chapter 3 he identifies a state of some chaos in the profession
on the question of the diet to be prescribed in cases of acute diseases; and he
follows this up with the remark that such disagreements are likely to make
laymen object that the rexvn is like divination, where diviners disagree
about which birds on the right or left are propitious and on what the signs
in the entrails portend.
Now that comparison is interesting for several reasons and chiefly because divination (avtiKt}) was in most quarters a highly respectable and
respected téxvn. When Prometheus boasts of the benefits he has brought
mankind, pavrın figures prominently; and On Regimen even cites it is as a
prime example of a Téxvn. Clearly, however, for the author of On Regimen
in Acute Diseases, if medicine were no better than divination, that would
not be enough. Yet we may note that one requirement he places upon the
doctor is to know features of the patient’s condition without being told,
that is, to practise ‘prognosis’, not here predicting the future, but inferring
the present, a practice medicine shared with divination (and the terms in
which both Prognostic 1 and Epidemicsi 5 speak of the doctor ‘telling in
advance the present, the past and the future’ indicate pretty clearly that
they were aware of the parallelism with prophecy).
Once again, as in On the Art, the author of On Regimen in Acute Diseases is led to explore topics to do with the nature of causation, particularly
in relation to the classification of diseases. One of the criticisms he has of
the revisers of the Cnidian Sentences is that though they were keen to
enumerate the types of each kind of disease, their account was incorrect;
and he goes on to complain that it is impossible to proceed on the assumption that any difference in the symptoms constitutes a different disease—or
again that a mere variety in the name does so. Again the problems posed
by the fact that the same condition may be due to different causes are
mentioned in chapter 11. It is a very serious error, for instance, to mistake
weakness that is due to the pain of an acute disease for weakness caused
by lack of nourishment and to feed the patient. Conversely, it is also an
error not to see that the weakness is due to such a lack.
That is not so
dangerous to the patient, but it does lay the doctor open to ridicule far
more. Another doctor or even a layman seeing what is the matter would
immediately be able to help the patient: that is the type of mistake that
leads to practitioners being despised by ordinary folk, while the doctor or
layman who comes in and saves the patient is like someone who raises him
from the dead.
On Regimen in Acute Diseases does recognize some insecurity in the
claims of medicine to be a Téxvn, and positively and constructively relies
on some detailed advice about diagnosis and especially the characteristics
Página 9
Ver en el PDF(se abre en una ventana nueva)of different treatments. The author of this treatise frequently criticises his
fellow-practitioners, often claiming that current practice and procedures
are mistaken: yet most of his recommendations take the form of contrary
assertions, the plausibility or persuasiveness of which depend entirely on
how convincing his appeals to his own experience sound.
On Ancient Medicine—my third text—has, however, much more to say
about methodology. This author attacks those who try to base medicine
on the new-fangled method of postulates (ümodeoeıs).
You may have to
rely on these in dealing with ‘meteorology’, where it is not clear ‘either
to the speaker himself or to his audience whether what is said is true or
not, since there is no criterion to which one should refer to obtain clear
knowledge’.
But that will not do in medicine: it would do there only if
medicine were no Téxvn at all and just a matter of chance [ch. 1: cf. ch. 12].
But that is not the case, as is shown by the differences between good and
bad practitioners.
Such argument depends, to be sure, on the successes
being agreed and being attributable to the Téxvn of those who achieved
them. But on that his chief point is that medicine has a principle (ápxí)
and a method (6865) which are tried and tested. It has been discovered (cf.
eùpnpa, ¿ytnpa) as the result of systematic inquiry: indeed he believes that
one day the whole of medicine will be discovered, using the same method
[ch. 8].
The claim is, then, that medicine has a methodology, delivers results, and
is not a matter of chance. But the particular argument the author advances,
connecting medicine with cookery and dietetics, in part to support a claim
that this was how the téxun started and to suggest its antiquity, has a
potentially embarrassing feature.
It is perfectly reasonable, he says in
chapter 4, that dietetics is not considered an art, because no one is a
layman in it, but all are knowledgeable since all have to use it.
But if
medicine starts from dietetics, trial and error procedures with the food you
eat and what you drink, at what point, precisely, it becomes a Texvn and is
not just what everyone knows, ought to be a question for the author to
take up: yet it is not one for which he has a very clear answer.
In other respects, however, he not only indicates the type of semiology
he suggests the doctor should practise in diagnosis and provides a number
of specific analyses of the effects of particular regimens, he also has further
points to add on the key question of isolating the causal factors that can
be held responsible for a condition.
Chapter 21 identifies as
a common
mistake among doctors as well as laymen the assumption that anything
unusual done near the beginning of a complaint was its cause—when it
may not be at all—and chapter 19 specifies that ‘we must consider the
causes of each condition to be those things which are such that, when
Página 10
Ver en el PDF(se abre en una ventana nueva)they are present, the condition necessarily occurs, but when they change
to another combination, it ceases’. It is striking that this statement of
causal factors that are, as we might say, necessary and sufficient conditions
of a disease was propounded in the context of particular problems posed
by medical diagnosis.
But this treatise makes an even more important contribution towards the
definition of the medical TExvn in its remarks on the degree of exactness (Td
atpexés, TO dkpiBés, and their cognates) which it can attain and which it
should be expected to attain. Chapter 9 begins by noting that substituting
weaker for stronger foods is far from effective treatment in all cases. The
matter is more complex and requires greater exactness. ‘One should aim at
some measure. But as a measure you will find neither number nor weight
by referring to which you will know what is exact, and no other measure
than the feeling of the body.’
Exactness is difficult to achieve and small
errors are bound to occur. Up to a point the subject can be, and has been,
made exact; but perfect exactness is unattainable.
But I assert that the ancient art of medicine should not be rejected
as non-existent or not well investigated because it has not attained
exactness in every item. Much rather, since, as I think, it has been
able to come close to perfect exactness by means of reasoning where
before there was great ignorance, its discoveries should be a matter
of admiration, as well and truly the result of discovery and not of
chance.
While the medical téxvn has achieved exactness in some areas, in others it
has not and it could never be expected to be perfectly exact: in particular,
it is positively inappropriate in medicine to attempt to use the measures
produced by numbering and weighing. To appreciate the full force of this
set of statements we must refer both to medical and to non-medical texts.
As is well known, the date of On Ancient Medicine is controversial, as
also is the question of who exactly are those whom this treatise criticises
for importing Ümoféoels into medicine. But it is less controversial, even if
not universally agreed, to identify mathematics as one domain in which a
method of bm68e0ts was developed before Plato: it is, after all, by reference
to how geometers proceed that Plato himself explains the method when it
is first introduced in Meno 86e, even though the term itself is not directly
attributed to them. It is possible, though far from certain, that the medical
writers attacked in On Ancient Medicine 1 were influenced by some mathematical usage; and I conjectured, some time ago, that Philolaus might
provide an appropriate bridge between medicine and mathematics.
know he was interested in both subjects and indeed the type of medical
Página 11
Ver en el PDF(se abre en una ventana nueva)and physiological theories attributed to him, which are based on the hot,
correspond broadly to those particularly criticised in On Ancient Medicine.)
But whatever we may think about a conjectured mathematical context
to the method of úróteors attacked in On Ancient Medicine, the author’s
remarks about exactness obviously resist some notion or tendency to turn
medicine into an exact inquiry. We need not look far for examples in the
Hippocratic Corpus itself of just such a notion or tendency.
The whole
topic of the periodicities of diseases is an extremely complex one. Different
texts set out different schemata, some based on odd/even contrasts (where
Pythagorean ideas are often seen in the background) and others using other
systems. Some such schemata are explicitly qualified as holding only ‘for
the most part’, even while others carry no such reservation. Prognostic, in
particular, after proposing an intricate theory of the periodicities of fevers,
goes on to remark [ch. 20] that the periods cannot be numbered in whole
days exactly—rather they are like the lunar month and the solar year. But
the evidence of a substantial group of texts points clearly in the direction of
their authors attempting precise, dogmatic theories in this area. Moreover
a similar controversy can be traced in regard to the question of exactness
in drug prescription, where some Hippocratic texts specify determinate
quantities, while others take a line closer to that in On Ancient Medicine
and insist that the ingredients and dosages have always to be adjusted
to particular patients. With its rejection of numbering and weighing, On
Ancient Medicine takes a stand on an issue about which the medical writers
were deeply divided: for some—whether or not they had the model of pure
or applied mathematics explicitly in
mind— were
all for turning medicine
into an exact inquiry, while others, as the author of this treatise, resisted
that ambition, though insisting nevertheless that medicine is a Téxvn based
on experience and reasoning.
Much more could be said, and many more texts adduced from the Hippocratic Corpus, to illustrate and elaborate these themes. But it is time to
draw some of the threads of this selective discussion together.
Medicine
exists in one form or another in every society, whether healing is entrusted
to specialists or not, to one group or to more. In the context of fifth- and
fourth-century Greece, where so much was being called into question, the
foundations of medicine and its status were made the subject of explicit
debate, maybe not earlier than other subjects, but among the earliest; and
that spirit of challenge itself raises a whole series of problems in a comparative perspective. In the process, as aspects of the pluralism of Greek
medicine and its relations with other inquiries became the topic of explicit
analysis, there was a heightening of self-consciousness and the construction
Página 12
Ver en el PDF(se abre en una ventana nueva)of not one but several overlapping and competing models of what medicine
is or should be.
Many of the issues were sharpened considerably with Plato’s insistence on
the distinctions among various Emıiotfjhaı, on the contrast between TExvn
and experience (éuterpta) or mere knack (TrptBñ), and on the differences
between Téxvat that were more or less exact, more or less tied to procedures
of measurement. But some of those questions are anticipated in earlier, or
made independently in contemporary, medical texts.
called a téxtm at all?
Could medicine be
Several Hippocratic writers were emphatic that it
could, though their ideas differ on how. Its successes are not the results of
chance but of reason based on experience, the effects of causal factors that
could be used by the Téxvn even when they were at work independently;
above all, predictions could be made on the basis of reliable signs, and that
was a test of the doctor’s skill. Some, whether or not aware of the problems
that remained if the Téxvn depended solely on the pragmatic criterion, went
further and insisted that medicine is an inquiry based on research conducted
according to its own methodological principles:
its theories should not
be based on arbitrary assumptions but should, in principle, be testable.
Above all, while some might suppose, and some did suppose, that there
was nothing to stop medicine being turned into an exact inquiry, others
resisted that ambition and insisted that though not perfectly exact, it was
a Texvn nevertheless.
As remarked, many of these themes become appreciably clearer and more
explicit with Plato—not that Plato was happy, in the final analysis, to concede to medicine, as a conjectural art, a very high status at all. With Plato
and with Aristotle of the Posterior Analytics, the requirement of certainty
for knowledge and the securing of incontrovertible conclusions by deduction from self-evident axioms, come into the foreground in philosophical
analysis—as they were implicitly to dominate (and to some extent were already dominating) the exact sciences throughout antiquity. But Aristotle’s
practice in the inquiry concerning nature accommodates more easily than
some of his theoretical pronouncements the category of what is true ‘for
the most part’ as well as what is true always; and of course he explicitly
allowed differences in the degree of exactness of different disciplines, not
just between mathematics and moral philosophy but also between mathematics and physics. Some of these Aristotelian themes may be represented
as picking up (though they do not do so explicitly) points already made
by Hippocratic writers, while in the next generations the continuing Hellenistic debates on the status and methods of the medical rexvn were to
be one context in which the issues between scepticism and dogmatism were
to be fought out. Sophisticated developments were to come: but whatever
Página 13
Ver en el PDF(se abre en una ventana nueva)we may think of the many different ways the name of Hippocrates was
conjured with in the Hellenistic medical sects, at least the first beginnings
of important topics are to be found in some of the treatises that came to be
ascribed to him.
