Whether land or sea animals are cleverer (0-2)

There can be little doubt that Plutarch composed this pleasant work from commentarii (ὑπομνήματα) derived not merely from Aristotle (mentioned specifically in 965 d and quoted often), but also from various other compendia, the remains of which are to be seen in Aelian’s and Pliny’s natural histories and elsewhere.[*] In fact, if one reads Plutarch and Aelian and Pliny side by side, one may acquire the impression that they had before them substantially the same sources, and that these were numerous. Whereas

The title is not well chosen, since the victory is awarded to neither side. The real point of the dialogue seems to be, in its second as well as its first part, that all animals of whatever provenance are intelligent.[*] The occasionally bantering tone may serve to indicate that we have before us something of a school exercise from Plutarch’s own academy, with perhaps the first draft of the second part composed by pupils.[*] Note the carefully established details: the contest will take place at a fixed time (960 b, 963 b) before their fellow-pupils and a specially appointed judge (965 c-e). More or less elaborate preparation has been made by the contestants (960 b, 975 d).[*] Because of the occasion the school has been granted a holiday.

In the first part (chapters 1-8), the author demonstrates through the authoritarian voice of his own father that the Stoics, in so far as they affirm the irrationality of animals, contradict their own tenets. The second part proves that animals of all kinds are rational (chapters 9-36); the last small section, while refusing to award first honours in the debate, appears to contain Plutarch’s exhortation to his pupils to continue the fight against the Stoics. For an excellent summary with sympathetic comments see E. R. Dodds, Greece and Rome, ii (1932/3), pp. 104-105.

D’ Agostino[*] and others have shown that there is little originality in Plutarch’s animal psychology, while not denying our author considerable vivacity in presentation. While it is true that whole sections, like 976 a-d, are drawn from the identical source that Aelian (De Natura Animalium, viii. 4-6) used, yet one has only to compare the use these authors have made of precisely the same material to recognize the great superiority of Plutarch. The principal sources have been disputed[*]: Chrysippus, Theophrastus, Hagnon, Alexander of Myndus,[*] Juba, Xenocrates have all been suggested, but there can be little doubt (as

It is by no means impossible that the work is incomplete in our mss.; there are, at least, several demonstrable lacunae and it is possible that it was considerably longer and may even have justified its title when it left Plutarch’s hands.

As for the date of the dialogue, the terminus post quem is a.d. 70 (not 79, as it cannot be certainly inferred from 974 a that Vespasian was then dead); it is probably a work of Plutarch’s youth, preceding in any case the Lives and the Symposiacs. It may well date from Plutarch’s anti-Stoic period which produced the De Facie, the De Communibus Notitiis, and the other anti-Chrysippean polemics. It has much in common with the Gryllus and the fragments of De Esu Carnium and some correspondence with the Amatorius.[*] It may, in fact, have been written during nearly the same period as that in which the elder Pliny (whose preface is dated a.d. 77) was compiling his own Natural History.

The citations in D’Arcy Thompson’s Oxford translation of Aristotle’s Historia Animalium [*] are somewhat inaccurate and inconsistent, being, as he says, compiled at various times and at long intervals during many years. Nevertheless the work is of great value and it may be hoped that the notes in this edition that rely on it (and these are many) have been adequately sifted. Also to be constantly and gratefully consulted are Thompson’s A Glossary of Greek Fishes (Oxford, 1947) and A Glossary of Greek Birds (2nd edition, Oxford, 1936). There will be many references to Thompson’s Aristotle; but if the creature in question is a bird or a fish, it is to be understood that supplementary and often corrective material is to be found in the Glossaries. There is, further, a tribute of admiration due to A. W. Mair’s L.C.L. edition of Oppian, with its exhaustive notes.[*] Rackham (L.C.L. Pliny, vol. Ill, books viii-xi) is very interesting on the text, but has almost completely denied himself the privilege of citing parallel passages.

The debunking of many of Plutarch’s stories, if such a task is necessary, has been pleasantly done in the leisurely course of Bergen Evans’ The Natural History of Nonsense (New York, 1946). It should be added, however, that modern scientific speculation is approaching somewhat closer to one of Plutarch’s main tenets, if one may judge from such a work as W. C. Allee’s Coöperation Among Animals (New York, 1951: a revision of his earlier The Social Life of

Both the translation and the notes of this and the following essays have benefited immeasurably from an exhaustive criticism generously given them by Professor Alfred C. Andrews of the University of Miami, Florida. He has in fact supplied a number of valuable notes and also the Appendix, a classified zoological index. It must be understood, however, that any errors remaining are to be attributed solely to the editor.[*]

The dialogue is no. 147 in the catalogue of Lamprias. According to this document Plutarch wrote another work (no. 135) on the same subject: Do Beasts Possess Reason? But no. 127, Περὶ ζώλων ἀλόγων ποιητικός, is probably the same as our Gryllus, the following dialogue in this edition.
