On Logic and Legislation.
Some Philosophical Remarks
Cristinel Munteanu1
Abstract: Starting from the conception of the ancient Greeks, which left deep marks in the Western
culture, I tried to comment in this study on the relation between cosmology, logic and legislation. I was
mainly interested in the connection between “natural law” and “social law” in general, but mostly in
the relation between the former and the principles of “Roman law”. Apart from the philosophical
aspects dealt with in this article, I have also presented some elements (connected to “repeated
discourse”) which I analyzed from a linguistic point of view as well.
Keywords: legislation; natural law; Roman law; logic; philosophy; repeated discourse
1. A connoisseur of the Old Greeks’ vision of the world, Werner Jaeger, in his
famous book, Paideia, proved that they “had an innate sense of the natural” and that
– unlike all the peoples which had established legal codes – they had always searched
for that unique LAW present in all things and had tried to harmonize their life and
thought with it (Jaeger, 1945, pp. xx-xxi). Minute observers of nature, the Old
Greeks intuited its order and strove to reproduce its natural rhythms in their own
activities. That is why the Greek natural science comes to be governed by a principle
according to which the world is imbued in Spirit. Jaeger also explained why the
Easterners had a totally different conception from that of the Greeks: “The soul of
the Orient, weighed down by religious yearning, sinks into the abyss of emotion, and
finds no firm foothold in it; but the Greek spirit, trained to think of the external
cosmos as governed by fixed laws, searches for the inner laws that govern the soul,
and at last discovers an objective view of the internal cosmos.” (Jaeger, 1945, pp.
152-153).

JURIDICA
1.1. Much later, during the Renaissance, this belief was radically changed, leading
to the idea that the natural world was “a machine in the literal and proper sense of
the word, an arrangement of bodily parts designed and put together and set going for
a definite purpose by an intelligent mind outside itself” (Collingwood, 1960, p. 5).
The great “Watchmaker” was no one else than God, the Divine Creator, the Almighty
Ruler of Nature. However, to the Old Greeks, the Universe was not a machine, but
an organism, and the pervasive spirit (above mentioned) was the intelligence of
nature itself. The modern cosmology is also based on an analogy: that between the
processes of the natural world (studied by naturalists) and the tumultuous human
actions (investigated by historians) (Collingwood, 1960, p. 9).
1.2. Returning to the Ancient Greeks, one should remark that the same reputed
German philologist, W. Jaeger, dealing with Anaximander (approx. 610 – approx.
546 BC) and with his doctrine regarding “the systematic justice of the universe”,
notices that a fundamental philosophical term, aitia ‘cause’ (together with the idea
itself), had already been transferred, in those times, from the terminology of law to
the that of physics. Similarly, related words such as cosmos, dike and tisis migrated
from the sphere of law to that of nature (Jaeger, 1945, p. 161)1. On the other hand,
one could observe a rather bizarre detail: “the physicists’ cosmos became, by a
curious retrogression in thought, the pattern of eunomia in human society, the
metaphysical foundation of city-state morality” (Jaeger, 1945, p. 171). Referring to
the respective regression, Jaeger probably alludes to the initial “natural” experience
of the Old Greeks (see supra), which was the source of the concepts ‘rhythm’, ‘form’
and ‘structure’, which they later applied to their art and science.
2. This reciprocal influence, coming either (1) from the natural macro-cosmos to the
human micro-cosmos, or (2) from the human conduct to the organization and
functioning of the universe, is “bizarre” only at first sight, if we consider the unity
which – in the Old Greeks’ mentality – the Spirit (already mentioned) should have
ensured, similar to a “fiber” common to all “things”.
2.1. According to John Dewey, the conception which had long dominated natural
sciences was derived from the latter type of influence: “The distinct classes to which
things belong by their very nature form a hierarchical order. There are castes in
nature. The universe is constituted on an aristocratic, one can truly say a feudal, plan.
Species, classes do not mix or overlap – except in cases of accident, and to the result

of chaos.” (Dewey, 1957, p. 59). The classical theory of the creation of the world
corresponds entirely to a hierarchical order of classes in terms of “dignity and
power”. In the opinion of the same American philosopher, the analogy between the
ancient cosmology and the social organization is a suitable one. It is common
knowledge that the feudalism is characterized, among other things, by an order
conferred by its military force, by the relation between the armed and the protected
etc. However, if one considers the notions of ‘rule’ and ‘order / command’, involved
by both sides, he will notice that such a vision is still present nowadays. The term
LAW is currently defined as a constant relation in the sphere of changes.
Nevertheless, we can still hear (quite frequently) of laws which “govern” events, and
thus we get the impression that, if there were no laws to keep them in order,
phenomena would manifest in a complete disorder. This way of thinking “is a
survival of reading social relationships into nature – not necessarily a feudal
relationship, but the relation of ruler and ruled, sovereign and subject. Law is
assimilated to a command or order.” (Dewey, 1957, p. 64).
2.2. Modern science has modified this opinion based on the relation between
‘superior’ and ‘inferior’. The wind of change was started by astronomy itself, which
demonstrated that the Earth was not in a privileged position and it definitely is not
above the Sun, the Moon and stars etc. Developing the same analogy, Dewey
believes that there would be no exaggeration in telling that a transfer from the feudal
system of the general classes of unequal rank, gradually distributed, to a democracy
of individual facts of an equal rank was thus produced (Dewey, 1957, pp. 65-66).
Certainly, such a change in “paradigm” also triggered a change in the way in which
things are researched. The principles and the scientific laws are not to be found at
the surface of nature. They have to be “extracted” from nature through a complex
and exquisite method, namely through the technique of inquiry. The old procedures
– the purely logical reason and the passive accumulation of observations – are
insufficient in this regard. On the contrary, the active experimentation, forcing the
natural facts to take shapes different from the usual ones, reaches sooner their truth,
“as torture may compel an unwilling witness to reveal what he has been concealing”
(Dewey, 1957, p. 32; also cf. Collingwood, 1971, pp. 246-256).

JURIDICA
3. We will see that all these transformations due to the modern scientific spirit finally
led to the needed reform of the Aristotelian logic, despite its so-called “immutable”
character (Pusca, 2006, pp. 8-9). But I will postpone, for the time being, the
discussion regarding the respective reform, trying to emphasize the primary
connection between logic and legislation or, better, the connection between logic and
law system. Since in the first part of my article I presented the relation between
cosmology and legislation in general (according to the Old Greek vision), in what
follows I aim at underlining the relation between logic and the Roman law. In my
research, I will frequently resort to some of the works of John Dewey, a great
American philosopher, for his ideas fully deserve our attention.
3.1. As known, the Roman law is still the basis of many legal systems worldwide.
Its norms regulated both a person’s juridical condition and the patrimonial personal
relations, and the activity of solving litigations between persons (Pusca, 2008, p. 12).
The Old Greeks were both philosophers and mathematicians, highly prone to
contemplation. However, the Romans, more pragmatic in nature, were excellent
lawyers and administrators. Theoretical reflections and investigations conducted for
the sake of speculation interested them less. Correct and systematic thinking was of
interest to them only if useful in the political life. Thus, in Rome, initially, logic was
subordinated to rhetoric, directing the oratorical activity, especially during Cicero’s
times, when the latter became extremely important in the case of civic rivalries.
Later, logic attained more prestige: “During the empire logic was the instrument for
organizing the complex legal body of rules and decisions under fixed general
principles, derived, if possible, from the ‘law of nature’. Logic thus became
definitely a formal discipline useful in arranging material for purposes of argument,
exposition and instruction.” (Dewey, 1933a, p. 6). Nevertheless, one should
remember that not only logic, but also the Greek philosophy in itself (either through
stoics or through other indirect ways) influenced the Roman law: the very concept
of ‘law’ originated in philosophy. Moreover, during the Middle Ages, “the idea of
the ‘law of nature’ was central in the ethical and political theories of the scholastic
thinkers” and, at the same time, “the organizing principle of all jurisprudence”
(Dewey, 1933b, p. 35).
3.2. The devastating (both civil and religious) wars of the 17th century gave an
impetus to the search of those norms meant to be applied in a more efficient and safer
manner to the empirical phenomena from the social and political sphere. It was
believed that the source of the respective norms was to be found in reason itself,
which was above any human and worldly hardships. That is why, Hugo Grotius
47
ACTA UNIVERSITATIS DANUBIUS
Vol. 16, no. 2/2020
(1583-1645), the great Dutch jurist, resumed the ‘law of nature’, giving it a new
interpretation and turning it into the generative and directive idea of international
law, with the view to regulating war and peace conditions1. Separating himself from
religion and theology, Grotius took more advantage of the benefits of logic: “[He]
revamped the law of nature of the mediaeval period to help rationalize international
relations, and his successors in various fields of jurisprudence and morals made his
method of appeal more and more stringently logical.” (Dewey, 1933a, p. 8; also cf.
Dewey, 1933b, p. 35).
4. Let us resume. So far, two rather distinct images of the ‘natural law’ are shaped:
(1) a LAW1 resulting from the passive (and, in a way, “superficial”) observation of
nature, a law in accordance with pure reason and, thus, with the (mainly deductive)
ancient Aristotelian logic; (2) a LAW2 resulting from the active experimentation of
nature, a law which, in order to be “extracted” from nature, requires a (partially) new
(mainly inductive) logic.
4.1. For almost two millennia, the former perspective was dominant. John Dewey,
in The Quest for Certainty, an extraordinary book, explains why things were
considered that way. The reason would be that, in an unpredictable world, man
searches for a secure place, striving to find a shelter. Thus, he has two solutions: (α)
either he tries to obtain the benevolence of the elements (through magic practices,
rituals, sacrifices etc.), (β) or he invents different crafts and, through them, he
manages to control the elements to his own benefit. In Aristotle’s time, the
intellectual activity (associated with leisure) was highly praised, while the physical
activity (for which slaves were mainly used) was not so much appreciated, since – it
was believed that – the “quest for complete certainty can be fulfilled in pure knowing
alone” (Dewey, 1960, p. 8), the only one capable to grasp the immutable. On the
contrary, “the realm of the practical is the region of change, and change is always
contingent; it has in it an element of chance than cannot be eliminated” (Dewey,
1960, p. 19). In this way, it is understandable why the line between theory and
practice was clearly drawn in the Old Greek’s vision. It corresponded to the border
of the two worlds, to which two different types of knowledge were attributed: “One
of them is alone knowledge in the full sense, science. This has a rational, necessary
and unchanging form. It is certain. The other, dealing with change, is belief or
1
In this regard, Hugo Grotius wrote a fundamental work (in three books): De iuri belli ac pacis (1625).
Some of his other essential treatises – Mare liberum (1609), De veritate religionis Christianae (1627)
etc. – are worth mentioning.

JURIDICA
opinion; empirical and particular; it is contingent, a matter of probability, not of
certainty.” (Dewey, 1960, p. 20).
4.2. The natural law (jus naturale) taken as a point of departure by Hugo Grotius,
even if still a law in its former meaning (LAW1), constituted rather a law of human
nature than one of physics or of the universe, although it surely had appeared – in
the Dutch jurist’s opinion – as a manifestation of God’s will1. Grotius’ hybrid
method, which he used in his treatises, is quite interesting: on the one hand, (a priori,
analytical) deductive; on the other hand, (a posteriori, synthetical) inductive2. The
following coincidence is worth mentioning: Hugo Grotius was Francis Bacon (15611626) and Descartes’ (1596-1650) contemporary. As known, these illustrious
thinkers were the representatives of the two great philosophical schools (different as
regards the methods used) which strongly influenced the Western culture of the last
centuries. Thus, (α) Fr. Bacon was the exponent of empiricism, which included those
who “appealed exclusively to experience in the form of sense perception as the
source of valid beliefs” (Dewey, 1933a, p. 8); the British philosophers adhered to
this orientation; while (β) Descartes was the exponent of rationalism, which included
those who “appealed to reason in the form of mathematical concepts as the ultimate
authority” (Dewey, 1933a, p. 8); the philosophers on the Continent adhered to this
orientation.
4.3. Modern science emphasized the other type of natural law (LAW2). Under its
impact, especially in the first half of the 20th century, a reform of the traditional logic
became necessary. Indeed, this aspect is clearly expressed in the fifth chapter of John
Dewey’s treatise, Logic. The Theory of Inquiry (1938). That chapter is entitled
precisely The Needed Reform of Logic, and it constitutes a balanced, sympathetic
criticism of the classic Aristotelian logic. Thus, on the one hand, the American
scholar shows the “intimate and organized” way in which Aristotle’s logic would
reflect the science of the period in which it was formulated: from this point of view,
this logic – having an ontological substratum – deserves our entire admiration. On
the other hand, Dewey tries to prove the fact that the “revolutionary” changes, which
previously happened in science, require a radical corresponding mutation in logic,
as well. For instance, the Ancient believed in the immutability of species (of

“essences”), being mainly interested in forms, and less in substances (as matter) –
which generally justifies their lack of preoccupation as regards measurement.
However, the quantitative criterion can no longer be ignored by modern science,
which prefers measurement. Moreover, Charles Darwin’s Origin of Species (1859)
– with a revolutionary title, as well – demonstrated exactly the fact that (biological)
species are not immutable at all (Dewey, 1938, pp. 81-98).
5. To Kant, logic, as founded and developed by Aristotle, seemed perfect. There was
nothing else to be added. To the same German philosopher, equally perfect were
mathematics and physics, as completed by Isaac Newton. Nevertheless, meanwhile,
both mathematics and physics progressed enormously and the respective advance
influenced logic, too. Let us ignore, at this point, the formalization of logic authored
by A. Whitehead, B. Russell et alii. Even more interesting is the fact that the microphysical experience (derived from discoveries such as Einstein’s theory of relativity,
Heisenberg’s principle of indeterminacy etc.) encouraged Stéphane Lupasco, for
instance, to propose a “dynamic logic of antagonism” and to theorize “the principle
of included middle”. Dewey also remarked this tendency: “Certain data discovered
by using the Einsteinian theory of relativity contradicted the Newtonian formula of
gravitation. If such negations had the independent and final logical status attributed
to them by traditional formalistic logic, either the Newtonian formula would have
been declared invalid and the matter would have ended there, or else the
observational data would have been declared false and impossible because they
contradicted the general proposition. Even in the cases in which an exception turns
out to be apparent rather than actual, the older generalization is not simply
confirmed, but gains a new shade of meaning because of its capacity to apply to the
unusual and seemingly negative instance. It is in this sense that «the exception proves
the rule».” (Dewey, 1938, pp. 196-197).
6. Some of the principles vehiculated by the Roman law seem to be equally
immutable. Not only do they preserve in a concise form obvious truths, but also
present themselves (and still circulate) in the prestigious garment of the Latin
language – very suitable, for Latin was often thought to discipline thinking thanks to
its extremely rigorous grammar, made up of mostly regular paradigms. Since the
logical principle of excluded middle itself was contested as a result of the discoveries
of modern science, one wonders if some of the truths preserved in the Latin juridical
formulae are also contestable. Certainly, as seen before, the natural law of the former
category (LAW1) can be contradicted, corrected or refined by the natural law from
the latter category (LAW2). Let us take, for example, a well-known juridical
50
JURIDICA
principle: Mater certa, pater incertus (‘The mother is certain, the father is
uncertain’). Nowadays, such a “law” (immutable in its millennial truth) can no
longer be held universally valid, because some “exceptions” have been observed in
the last decades. At this point, we have to make a distinction: a principle can be justly
contested either (α) as regards its content or (β) as regards its expression (only in this
order, since β, if produced, derives from α).
6.1. As regards its content, it is stated that the principle Mater certa, pater incertus
lost its validity some decades ago, when surrogate mothers appeared (Pusca, 2009,
p. 386), being able to bear and deliver children conceived through the technique of
in vitro fertilization; thus, mothers were instantly not as “certain” as before... On the
other hand, due to genetics, lately fathers have not been as “uncertain” as before
either, for they can be precisely identified with the help of DNA tests. The Germans,
for instance, improved the respective principle by adding (in 1997) in their Civil Law
a paragraph concerning “maternity”, according to which “the mother of a child is the
woman who gave him birth” (for further details, see Duggan, 2014, pp. 1-23).
However, this is also a rather clear example proving that sometimes the logic of
common sense, based on the long-term observation of nature, takes (together with
the norms of the Roman law) a step backwards due to the scientific progress.
6.2. When considering the expression as such, we find ourselves on the field of
‘repeated discourse’ (as Coseriu broadly names phraseology), which is of interest to
linguistics. Moreover, one can recognize the technique through which the phrases
which belong to repeated discourse are modified according to quadripartita ratio
(Quintilian), which Stelian Dumistrăcel fully dealt with. He is justified in saying that
this type of phrases are submitted to changes that can be grouped in [only] the four
“figures of construction” referred to as “solecisms” by Quintilian in Institutio
Oratoria, that is: detractio (suppression), adiectio (addition), immutatio
(substitution) and transmutatio (permutation).
I will illustrate them, on my account, in what follows, with some Latin phrases and
sayings:
(1) SUPPRESSION – is used when, in some contexts, it is enough to say just verba
volant or scripta manent, there being a left or right suppression of the phrase verba
volant, scripta manent;
(2) ADDITION – homo homini lupus (est) became in the Middle Ages homo homini
lupus (est), femina feminae lupior, clericus clerico lupissimus;
51
ACTA UNIVERSITATIS DANUBIUS
Vol. 16, no. 2/2020
(3) SUBSTITUTION – Plautus’ formula, homo homini lupus (est) is changed at various
classics in homo homini deus est (Caecilius) or homo res sacra homini (Seneca);
(4) PERMUTATION – ubi bene, ibi patria was inverted by nationalists: ubi patria, ibi
bene. All types of modification go under these four categories: there are not more
(they are universal), just as there are only four cardinal points (see, for more details,
Munteanu, 2013, pp. 27-40).
7. By way of conclusion, let us refer, once again, to the principle of Roman law
aforementioned. I have to remind our readers that this circulates in different forms:
Mater semper certa est; pater est, quem nuptiae demonstrant (Dig., 2, 4, 5, Paulus);
Mater jure semper certa est (Dig., L.5, De in jus vocando, 2, 4) etc. (see Motica &
Negrescu, 2001, p. 162). But the most frequent version is Mater (semper) certa est,
pater incertus. As concerns the changes of this formula belonging to the Latin
juridical repeated discourse, it is obvious that the innovations produced by recent
science motivated all its possible formal changes (only four, as in Quintilian’s
typology). A quick search on the Internet, using Google, will reveal all kinds of
modifications. I will only record here the rarest type of modification encountered,
namely permutation. For instance, two French researchers declared (in 1994), in a
book about “nobody’s child”, that the principle Mater semper certa est, sed pater
semper incertus became obsolete because of the tremendous scientific revolution.
Consequently, they stated that – in the current context – the most appropriate formula
would be Pater semper certus est, sed mater non certa (Delaisir & Verdier, 1994, p.
46).
