Epicurus denies that human beings have natural parental love for their children,Footnote 1 and his account of the development of justice and human political community does not involve any natural affinity between human beings in general but rather a form of social contract.Footnote 2 The Stoics to the contrary assert that parental love is natural;Footnote 3 and, moreover, they maintain that natural parental love is the first principle of social οἰκείωσις,Footnote 4 which provides the basis for the naturalness of justice and human political community.Footnote 5 The Stoics are, therefore, obliged to refute Epicurus’ denial of the naturalness of parental love in order to support their own theory of social οἰκείωσις; and we have good evidence for the arguments that they employed against the Epicureans on this account.Footnote 6 Likewise, the Epicureans are obliged not only to defend their own position but also to undermine the competing Stoic theory of social οἰκείωσις; and the foundational premise of a natural bond between parent and child is an obvious target. However, beyond dogmatically restating Epicurus’ denial of natural parental love, the evidence for the Epicurean line of attack against the Stoics is currently unclear. In this paper I argue that we can go some way towards uncovering it via an analysis of some fragmentary passages from an unidentified work of the Epicurean Demetrius of Laconia (c.150–75 b.c.) that contain a puzzling discussion of Epicurus’ stance on parental love.
Demetrius of Laconia was a prolific author, some of whose works survive in fragments among the Herculaneum papyri.Footnote 7 He was a contemporary of the Epicurean Zeno of Sidon (who was a teacher of Philodemus) and active during the late second and early first centuries b.c.Footnote 8 His surviving work portrays a combative character who engaged in debate with critics of Epicurus (for instance, in On Signs Philodemus provides a detailed account of Demetrius’ response to critics—most likely Stoics—whom he considers have misunderstood Epicurean views on methods of inference; cols. XXVIII–XXX De Lacy and De Lacy)Footnote 9 and who sought to resolve internal disputes and inconsistencies within the Epicurean school, concerning both the authenticity of various views attributed to Epicurus himself in later Epicurean texts and the interpretation of Epicurus’ teachings (for instance, Sextus Empiricus records his interpretation of Epicurus’ declaration that ‘time is an accident of accidents’; Math. 10.219–27).Footnote 10 The evidence concerning parental love is as follows:

This evidence has received little critical scholarly attention: Brown suggests that Demetrius ‘argues on Epicurean grounds that the love of parents for children is natural’ (and so rejects Epicurus’ own thesis);Footnote 13 both Puglia and Alesse maintain that Demetrius is addressing a contemporary debate within the Epicurean school, proposing that some later Epicureans were unhappy with either the soundness or the authenticity of Epicurus’ denial of the naturalness of parental love.Footnote 14 I question the cogency of these interpretations: a fresh analysis of the material reveals that Demetrius is defending Epicurus’ thesis by presenting a sophisticated but otherwise unattested dialectical argument against the Stoics on the topic of parental love.
In the first section I outline the dogmatic arguments denying the naturalness of parental love that are present in other Epicurean texts so as to highlight the distinctive nature of Demetrius’ argument. In the second section I undertake a close reading of the fragmentary texts and show that Demetrius is engaging with Stoic ideas, indicated in particular by his use of technical Stoic philosophical vocabulary, in an attempt to force the Stoic critic to draw the Epicurean conclusion from his own Stoic premises.
1. A NEW EPICUREAN ARGUMENT
The preceding and the following columns in P.Herc. 1012 appear unrelated and do not help us locate the three passages in a wider discussion, so we are left to reconstruct matters solely on the basis of columns LXVI–LXVIII. In column LXVI Demetrius tells us that Epicurus asserts that we do not have natural parental love for our children at all and that there is a dispute about this claim. For, despite being shown that, if love for one's children were natural, it must arise by necessity, certain people say that Epicurus’ view is absurd. Pace Brown, it appears that Demetrius is committed to defending Epicurus’ claim that parental love is not natural. It is immediately striking that Demetrius’ explanation, which relies on the claim that parental love is not natural because it is not necessary, does not obviously replicate either of the two dogmatic arguments that we see in other Epicurean texts.
First, Demetrius does not address parental love in the framework of the hedonic calculus. Plutarch reports Epicurus’ views on human familial love as follows: ‘it is for a return (μισθός) that a father loves his son, a mother her child, and children their parents’ (De amore prolis 495A). According to Epicurus, we determine each and every choice or action by weighing the pleasures and pains it brings us;Footnote 15 evidently parental love is also the result of a rational weighing of the advantages and disadvantages to oneself of loving one's child.Footnote 16 It follows that parents may or may not love their children depending on the outcome of a rational hedonistic deliberation: parental love is a choice. It would appear, then, that parental love is not natural simply because it is not hard-wired into human beings: it is not a brute biological fact of human nature, which would imply that it is not subject to the hedonic calculus; nor does it appear to be a ‘natural emotion’, an unavoidable physical ‘bite’ or ‘sting’ like grief or anger (cf. for example Phld. On Anger cols. XL–XLI Indelli, On Death col. XXV.2–9 Henry; 120 Usener).Footnote 17 To be sure, this hedonist argument does not deny the reality or ubiquity of parental love, nor does it presuppose an absence of any feelings on the part of the parent towards the child. Rather, it draws a distinction between any raw emotive feelings a parent might have, in the basic Epicurean sense where πάθη indicate whether something is an immediate source of pleasure or pain,Footnote 18 and a reflective judgement on whether to love the child. Such feelings are factors in the deliberation that might sway things heavily towards choosing to love the child; for on the basis of a πάθος one might judge that the child is a source of pleasure. But do such immediate feelings and the potential future pleasures outweigh the pains that might arise from loving the child, involving economic and other considerations—for instance, if one cannot afford to raise the child? In such cases a choice might be made to expose the child or to not love it, despite such immediate feelings. This is the sort of deliberation the Epicurean hedonist faces; and parental love is deemed a result of a reasoned judgement about advantages to oneself.
Second, Demetrius does not present parental love as being a result of human cultural development. In De rerum natura Lucretius places marriage before child-rearing in the first stages of the development of human communities (5.1011–18). In the state of nature human beings are originally unattached individuals (5.958–61) and there appears to be no relationship between parent and child beyond the biological facts of birth: there is no notion of any impulse to care for one's offspring; nor is there any notion of parental possession or ownership of one's children.Footnote 19 Human reproduction is explained as being a result of chance sexual encounters between unattached individuals, at times involving rape, prostitution or bribery (5.962–5). Lucretius does not mention the lot of the resulting children at all. Elsewhere he stresses the vulnerability of human babies and the care needed if they are to survive (5.222–34, 5.1026–7), but perhaps he assumes that in the state of nature new-born humans were merely left to their own devices after birth, and by chance some happened to survive and become the unattached individuals he describes. At any rate, human beings do not appear to have any concerns at all about children until such time as the formation of domestic units and the softening effects of fire, of easy access to sex and of exposure to the sweet charms of their own children, which result (5.1015–18). At this stage of human cultural development, owing to a collective concern for security, friendships or alliances emerge, as well as justice in the form of a social contract neither to harm nor to be harmed (5.1019–23). Lucretius says explicitly that men included in such an agreement a provision for the protection of their women and children, for it is fair to pity the weak. This suggests a real degree of love for one's children, a desire for their well-being, that is at odds with the strictly egoistic thinking usually involved in Epicurean practical reasoning.Footnote 20 Setting aside that vexed issue for the moment, on this Epicurean model affectionate bonds between parent and child arise at a relatively late stage of human civilization and only following the softening of human nature, which finds its full unadulterated expression in the state of nature.Footnote 21
In his commentary on these lines Campbell contends that at this stage human nature changes so that parental love for one's children is indeed now a natural impulse: ‘For humans with their slow-maturing offspring, an innate psychological inclination towards caring for children is as much a mechanism for survival as strength for lions (5.862) and speed for deer (5.863).’Footnote 22 This interpretation maintains that parental love is natural now, but was not originally, which hardly gives due weight to Epicurus’ reported denial of the naturalness of parental love and affection. Rather, the force of Lucretius’ argument appears to be this: parental love is simply not natural, for without culture to soften human nature there would be no affectionate bonds between parents and children; parental love was and continues to be a result of cultural influences and, pace Campbell, present human beings do not have an innate psychological inclination towards caring for their offspring that qualifies parental love as being natural.Footnote 23
Demetrius’ argument denying the naturalness of parental love takes a different approach to the issue. In the next section I reconstruct the full details of Demetrius’ argument and demonstrate how it functions as a dialectical refutation of the opposing Stoic view on parental love.
2. DEMETRIUS AGAINST THE STOICS
Whom does Demetrius have in mind when he refers in column LXVI to certain people who say that Epicurus’ view is absurd? There are three broad possibilities: they are members of the Epicurean school; they are philosophical opponents of the school; they are a generalized set of people, some of whom may be undertaking formal basic education in Epicureanism. At first blush, owing to the fact that these people are prepared to say that they find Epicurus’ view absurd, they appear to be outsiders of the school, either philosophical opponents or a generalized set of people. Puglia and Alesse, however, make the case that they are most likely Epicureans who themselves were unhappy with Epicurus’ reported view on parental love.Footnote 24 They argue that Demetrius has a habit of engaging in internal school debates and that he seeks to secure greater doctrinal consensus and continuity, which is certainly true.Footnote 25 In particular, elsewhere in this unidentified treatise (P.Herc. 1012)—which Puglia entitles ‘Problems in the text of Epicurus’ (Aporie testuali ed esegetiche in Epicuro)—Demetrius seeks to establish and defend certain philological criteria both to justify Epicurus’ phrasing (which is sometimes odd and difficult to follow) and to discriminate between what is genuinely from Epicurus and what is erroneous material that has entered the manuscripts and later Epicurean digests and compendia (for example, cols. XXII, XXXI, XXXV, XLI Puglia).Footnote 26 Alesse suggests that the Greek τῶν διδασκαλιῶν in line 2 of column LXVI might also refer to doctrines in such later Epicurean texts.Footnote 27 Further, they argue that the Greek ταραχθήσεται in line 5 of column LXVI (and ταραχθή in line 9 of column LXVII) captures the sort of psychic disharmony that would beset a person who has accepted a number of Epicurus’ claims, but then strikes one they really cannot handle—perhaps despite all argumentation to convince them. This also accords with the first line of the column, which indicates some sort of contradiction (ἀντίθεσις) between precepts. So, presuming that κα̣ὶ̣ π̣ῶς in line 5 maintains continuity between what precedes and what follows, either these people cannot reconcile their own beliefs as Epicureans since they cannot accept the denial of natural parental love, or they claim that Epicurus himself has failed to reconcile his ideas, as the texts are inconsistent. In either case, it is an internal school issue, and Demetrius seeks to solve both problems in this part of the treatise. Moreover, we know that there were divergences in the Epicurean school around the first and the second centuries b.c. concerning sensitive ethical topics such as friendship, with certain ‘more timid’ (timidiores) figures seeking to weaken or qualify Epicurus’ original claims so as to allow a greater degree of other concern and to bring the Epicureans more in line with commonly held attitudes (Cic. Fin. 1.65–70); perhaps the topic of parental love met a similar fate.Footnote 28
Puglia and Alesse certainly have a plausible case.Footnote 29 However, κα̣ὶ̣ π̣ῶς in line 5 of column LXVI appears to indicate a transition to a new point, which deflates much of the force of their argument. I suggest that it is more likely that these people who say that Epicurus’ view is absurd are outsiders. In particular, I think we can discern that Demetrius has in mind a Stoic opponent, or at least a person who is both familiar with and sympathetic towards Stoic precepts. Such a candidate accords readily with the fragmentary text of the columns.
For a start, the Stoics clearly consider it absurd to claim that parental love is not natural. In particular, despite ‘having been shown evidence by many that, if love towards children were natural, it would arise by necessity’ (col. LXVI.9–15 Puglia), they think that the evidence indicates that parental love indeed does arise ‘by necessity’. In fact, they insist on the naturalness of parental love in so far as it is: (1) a virtue and as such is always advantageous (for example, Diog. Laert. 7.120; Clem. Al. Strom. 2.9.41.6; SVF 3.62 Ant.; Arr. Epict. Diss. 1.11, 3.24.58–118; M. Aur. Med. 1.17.7, 2.5, 6.30.1, 11.18.9);Footnote 30 (2) a proper function of the human organism and as such expressed unless somehow distorted (for example, Arr. Epict. Diss. 1.11; Cic. Dom. 97–8; Rosc. 40–1, 52–5, 62–3); (3) something necessary or unavoidable: as Epictetus says, ‘once a child is born it is no longer up to us not to love and care for it’ (ἂν ἅπαξ γένηται παιδίον, οὐκέτι ἐφ’ ἡμῖν ἐστι μὴ στέργειν μηδὲ φροντίζειν ἐπ’ αὐτῷ, Arr. Epict. Diss. 1.23.5).
The Stoics indeed hold that parental love fits all the criteria for naturalness listed in column LXVII. There Demetrius gives some examples of the ways in which ‘by nature’ (φύσει) is said, in order to illustrate some qualifying traits: being able to procure nourishment is ‘by nature’, in so far as it involves the uninterrupted or undistorted functioning of the human organism (ἐπειδήπερ ἀδιαστρόφως); being able to bear pain is ‘by nature’, in so far as pain is necessary or unavoidable (ἐπειδὴ κατ{ατ}ηναγκασμένως); seeking virtue is ‘by nature’, since it is advantageous (ἐπεὶ συμφερόντως)—presumably, it instantiates or is the means to our natural end; and speech is ‘by nature’, but the text breaks off before we are told why. There are then (at least) three senses in which something qualifies as ‘by nature’: it is an aspect of ‘proper functioning’; it is ‘necessary’; it is ‘advantageous’, presumably in the particularly strong sense where it is never disadvantageous (as in the case of virtue).Footnote 31 One can anticipate that Demetrius will demonstrate that parental love fails to meet any of these conditions.
In column LXVIII Demetrius focusses on a proof that parental love is not ‘by necessity’ and so, I suggest, he seeks to demolish that particular claim for the naturalness of parental love.Footnote 32 He presents what he obviously thinks is a simple and devastating proof:
-
1) Love for one's children is not natural because it does not arise necessarily, and the lack of necessity is proven by the simple fact that not all human beings love their children.
-
2) We can also determine that love for one's children does not arise necessarily, because it does not have the distinctive (ἴδιον) feature of the unwilling or the involuntary that accompanies things that arise by necessity.
-
3) We can tell that love for one's children lacks such a distinctive feature because resistance (ἀντίπραξις), which is a consequence (παρακολούθημα) of the unwilling or the involuntary, is missing.
The argument appeals to empirical evidence to refute the claim that parental love is natural on the basis that it is ‘by necessity’ (κατ’ ἀνάγκην). If parental love were natural in the sense of arising ‘by necessity’, then all human beings would unavoidably, as a matter of course, love their children, but the empirical evidence does not confirm the prediction and that suffices to prove Epicurus’ point. Moreover, the necessary accompaniments of what is ‘by necessity’ are not apparent in the case of parental love: again the evidence does not confirm the prediction if parental love is in fact natural. This second point depends on an analysis of what ‘by necessity’ means or entails, in particular when it comes to human choices and actions: Demetrius relies on the notion that ‘necessity’ is coercive, so that, if something is ‘by necessity’, it follows that there is no possible way one could do otherwise, even if one chooses or desires otherwise (there is no real choice, as the outcome is unavoidable).Footnote 33 The Stoic flavour of this discussion is indicated most of all by the pedigree of the terms ἀντίπραξις (‘resistance’) and παρακολούθημα (‘consequence’).
Let us take the case of ἀντίπραξις first. There is no other extant example of an Epicurean using the term,Footnote 34 and somewhat surprisingly there is no extant evidence for any philosopher using it before Demetrius himself. Indeed, ἀντίπραξις is a rather rare word in the entire extant Greek corpus, with most examples surviving in much later authors.Footnote 35 Intriguingly, the Suda lists ἀντίπραξις along with νόησις (‘intelligence’) as the definition of ὑπόληψις (‘understanding’). The contrast with νόησις suggests that ἀντίπραξις involves some sort of error, and so ἀντίπραξις means something like ‘opposing view’, where that view is flawed. A sense of opposition to some sort of compelling force or correct opinion accords in broad terms with most of the other extant usages of ἀντίπραξις; but in particular it resonates with instances of ἀντίπραξις in later Stoic sources, where it appears to function as a technical term in the context of their theory of action.
In a fragmentary column of Hierocles’ partially extant second-century a.d. treatise Elements of Ethics (ἠθικὴ στοιχείωσις), which contains an account of self-perception that is premised on the Stoic theory of οἰκείωσις,Footnote 36 an instance of ἀντίπραξις survives, although there is unfortunately too little context to judge its precise meaning (col. XII.13).Footnote 37 It is a passage from Epictetus (a.d. 55–135), preserved by Stobaeus (fifth century a.d.), which forms our best evidence for the term's technical Stoic meaning (Stob. Ecl. 4.44.66 = Epictetus fr. 3 Oldfather):
πάντα ὑπακούει τῷ κόσμῳ καὶ ὑπηρετεῖ καὶ γῆ καὶ θάλασσα καὶ ἥλιος καὶ τὰ λοιπὰ ἄστρα καὶ τὰ γῆς φυτὰ καὶ ζῷα˙ ὑπακούει δὲ αὐτῷ καὶ τὸ ἡμέτερον σῶμα καὶ νοσοῦν καὶ ὑγιαῖνον, ὅταν ἐκεῖνος θέλῃ, καὶ νεάζον καὶ γηρῶν καὶ τὰς ἄλλας διερχόμενον μεταβολάς. οὐκοῦν εὔλογον καί, ὃ ἐφ’ ἡμῖν ἐστί, τουτέστι τὴν κρίσιν, μὴ ἀντιτείνειν μόνην πρὸς αὐτόν˙ καὶ γὰρ ἰσχυρός ἐστι καὶ κρείσσων καὶ ἄμεινον ὑπὲρ ἡμῶν βεβούλευται μετὰ τῶν ὅλων καὶ ἡμᾶς συνδιοικῶν. πρὸς δὲ τούτοις καὶ ἡ ἀντίπραξις μετὰ τοῦ ἀλόγου καὶ πλέον οὐδὲν ποιοῦσα πλὴν τὸ διακενῆς σπᾶσθαι καὶ περιπίπτειν ὀδύναις καὶ λύπαις ποιεῖ.
All things obey and comply with the cosmos—land and sea and sun and the remaining stars and the plants and animals of earth. And our body obeys it—sick and healthy, young and old, and passing through the other changes—whenever the cosmos wishes. Therefore, it is reasonable too that the very thing which is ‘up to us’, namely our decision-making capacity, should not be the only thing to offer resistance towards it. For it is mighty and more powerful [than us] and it has decided more rightly for us [than we could], arranging us too together with the whole universe. Furthermore, resistance is irrational, and while it accomplishes nothing more than jerking us around in vain, it makes us fall into pains and agonies.
The passage contains a description of the universal reach of nature's power, including over our κρίσις, our decision-making capacity. In this context, ἀντίπραξις involves striving to act against nature's power and design, which involves acting contrary to reason (it is ἄλογον rather than εὔλογον). Crucially, any such choice is futile and will not come to fruition because it goes against the power of nature, against what is necessary: one will ‘accomplish nothing’ and be ‘jerked around in vain’. As such, ἀντίπραξις appears to capture the notion of being compelled to act against one's choice, that is, unwillingly or involuntarily or ‘counter-voluntarily’: one wishes to do something different (something that goes against the path ordained by nature) and yet nature prevails. In such cases there is an attitude of resistance rather than voluntary assent to nature's prompting, even though in physical terms the same action ultimately takes place.
The Stoic analogy of the dog and the cart reported by Hippolytus of Rome (a.d. 170–235) contains similar motifs and helps to clarify things here (Hippolytus of Rome, Refutation of All Heresies 1.21 = SVF 2.975):
καὶ αὐτοὶ δὲ τὸ καθ’ εἱμαρμένην εἶναι πάντα διεβεβαιώσαντο, παραδείγματι χρησάμενοι τοιούτῳ· ὅτι ὥσπερ ὀχήματος ἐὰν ᾖ ἐξηρτημένος κύων, ἐὰν μὲν βούληται ἕπεσθαι, καὶ ἕλκεται καὶ ἕπεται, ποιῶν καὶ τὸ αὐτεξούσιον μετὰ τῆς ἀνάγκης [οἷον τῆς εἱμαρμένης]· ἐὰν δὲ μὴ βούληται ἕπεσθαι, πάντως ἀναγκασθήσεται. τὸ αὐτὸ δήπου καὶ ἐπὶ τῶν ἀνθρώπων· καὶ μὴ βουλόμενοι γὰρ ἀκολουθεῖν ἀναγκασθήσονται πάντως εἰς τὸ πεπρωμένον εἰσελθεῖν.
They too [Zeno and Chrysippus] affirmed that everything is fated, with the following model. When a dog is tied to a cart, if it wants to follow, it is pulled and follows, making its spontaneous act coincide with necessity, but if it does not want to follow, it will be compelled in any case. So it is with men too: even if they do not want to, they will be compelled in any case to follow what is destined. (trans. Long and Sedley)
The moral is that resistance is futile and it is rational to assent to nature's causal processes, thus placing oneself in harmony with nature (cf. SVF 1.527). In the Stoic theory of action, assent to nature's prompting (which comes in the form of impressions—φαντασίαι) generates an impulse (ὁρμή) that motivates a rational action, which the Stoics term a πράξις (for example, SVF 2.1002; Diog. Laert. 7.108);Footnote 38 and by living in accordance with nature one leads a tranquil and happy life.Footnote 39 The alternative is to seek to go against nature, which is contrary to reason and a futile course of action—one can resist but be dragged along unwillingly none the less, suffering in the process. The evidence available is admittedly both scanty and from the Imperial period, but I posit a tentative conclusion: in contrast with πράξις it appears likely that the Stoic label for an action that takes place without assent to nature's prompting—and indeed specifically with active resistance against it (not the neutral withholding of assent but actual dissent)—is ἀντίπραξις. The question of whether or not this was already the case when Demetrius was writing in the late second or early first century b.c. is of course unresolvable with any degree of certainty.
At this point, however, we can consider further the scope of the term παρακολούθημα (‘consequence’) in Demetrius’ column LXVIII. Uses of the verb παρακολουθέω (‘to follow closely’ or, figuratively, ‘to understand’) are extremely common in the extant Greek corpus, but uses of the noun forms τὸ παρακολούθημα and ἡ παρακολούθησις are surprisingly rare (the vast majority of instances are concentrated in much later philosophical authors such as Ammonius, Porphyry, Plotinus, Simplicius, Philoponus and Iamblichus).Footnote 40 There is no extant example of an Epicurean using either τὸ παρακολούθημα or ἡ παρακολούθησις other than Demetrius in column LXVIII, and once again the Stoic pedigree appears crucial in decoding Demetrius’ use of the term.Footnote 41 The key interpretative question is whether παρακολούθημα designates that ἀντίπραξις is a necessary or an incidental consequence of ‘the involuntary’. A surviving example of ἡ παρακολούθησις in Stoicorum veterum fragmenta suggests that it is a necessary consequence of a very particular kind: Aulus Gellius (a.d. c.123–170) reports that in his discussion of theodicy in the fourth book of his On Providence (περὶ προνoίας)—a treatise addressing various issues pertaining to fate, freedom and necessity—Chrysippus (c.279–206 b.c.) uses the technical phrase κατὰ παρακολούθησιν to denote the specific causal processes that lead to ‘an inevitable or necessary consequence’, with examples of negative by-products of nature's good designs, such as disease and vice and the vulnerability of the human head, firmly in mind (NA 7.1.1–13 = SVF 2.1170).Footnote 42 The phrase κατὰ παρακολούθησιν captures a key Stoic thought, namely that certain things are inevitable negative consequences of nature's good design—the possibility of virtue brings with it the possibility of vice, health the possibility of disease, and so forth—but themselves should not be considered κατὰ φύσιν or per naturam (‘according to nature’). A particular bad thing that results κατὰ παρακολούθησιν (‘as a consequence’) rather than κατὰ φύσιν (which would make it a good thing) might well be coined a παρακολούθημα (‘a thing which follows’)—and, from what we have seen in the Suda and in later Stoic sources such as Epictetus, ἀντίπραξις is indeed such a bad thing that is not κατὰ φύσιν but κατὰ παρακολούθησιν: either it is the negative by-product of the good faculty of understanding (ὑπόληψις) and as such is contrasted with right thinking or νόησις; or it is the negative by-product of our having a decision-making faculty (κρίσις) that is up to us and as such is contrasted with right action or πρᾶξις, which involves proper assent to nature's prompting.
Chrysippus’ Investigations in Logic (P.Herc. 307) and On Providence (P.Herc. 1038, 1421) have been identified among the Herculaneum papyri, which suggests that the Epicureans were reading him and perhaps directly critiquing his work.Footnote 43 Moreover, in Philodemus’ On Signs (cols. XXVIII–XXX De Lacy and De Lacy) it appears that Demetrius himself was familiar with Stoic views on logic and able to criticize their objections to Epicurean precepts.Footnote 44 Although the evidence is largely circumstantial, it seems to me highly likely that in P.Herc. 1012 Demetrius is discussing criticisms of Epicurus’ position on parental love in a recognizably Stoic framework.
At any rate, the Stoic connotations of the terms ἀντίπραξις and παρακολούθημα accord readily with the force of Demetrius’ argument in column LXVIII, which we can now interpret as a dialectical justification of Epicurus’ denial of the naturalness of parental love in the following manner. Demetrius posits a Stoic premise: he states that ἀντίπραξις is an inevitable consequence (παρακολούθημα) of the unwilling or involuntary—that is, ἀντίπραξις arises when one assents to a course of action that is contrary to nature and hence futile, leading to pain and distress, which only occurs in the case of those things that happen ‘by necessity’ (κατ’ ἀνάγκην).Footnote 45 From this Stoic premise he reaches an Epicurean conclusion: ἀντίπραξις is not an inevitable consequence (παρακολούθημα) in the case of parental love, for the simple reason that parental love is not a matter of necessity; despite Stoic claims that ‘once a child is born it is no longer up to us (ἐφ’ ἡμῖν) not to love and care for it’ (Arr. Epict. Diss. 1.23.5), if parental love truly were ‘by necessity’, then one might expect that a parent could be pulled along like the dog tied to the cart, compelled to love his child despite resistance against nature's prompting—but that, observes Demetrius, is just not the case (‘and resistance is a consequence of the involuntary/unwilling, which clearly is absent from the love of one's children’, col. LXVIII.5–9 Puglia): either parents choose to love their children willingly and do (however much they curse the decision or depict it as a ‘necessary’ imposition to which they have not assented), or willingly choose not to and do not (they expose their children and so forth); hence parental love is not by necessity and hence, as Epicurus states, it is not natural.
3. CONCLUSION
The fragmentary evidence from P.Herc. 1012 cols. LXVI–LXVIII is not a denial of Epicurus’ claim that parental love is not natural, nor is it indicative of internal debates within the Epicurean school; rather, it forms a robust dialectical critique of the opposing Stoic position on the naturalness of parental love. I defer judgement on the cogency of the argument or on the possible Stoic responses to it; suffice it to say that the Stoics clearly did not abandon their position. The vigour and the urgency of Epicurean engagement with the Stoics increases noticeably in the late second and early first centuries b.c.,Footnote 46 and this neglected material from Demetrius of Laconia provides further evidence of both the complexity and the scope of inter-school ethical debate during this period.
