In his dialog titled "The Statesman", Plato goes into a good deal more detail; ancients clearly viewed communication with other species as a widespread and common thing prior to the flood.
Nonetheless, there is no way humans could ever communicate with animals using spoken language, in fact the ONLY reason chimps and gorillas cannot be taught to speak English is that they lack voluntary control over breathing (which Elaine Morgan notes is an adaptation for aquatic life). Communication with animals would have to be via something other than our present spoken speech.
Some of the gorillas which have learned to communicate via deaf signs show IQs in the 100 - 110 range, which is more than adequate for half of all jobs in the US.
From Plato's "The Staesman":
Y. Soc. Certainly that is quite consistent with what has preceded; but tell me, was the life which you said existed in the reign of Cronos in that cycle of the world, or in this? For the change in the course of the stars and the sun must have occurred in both.
Str. I see that you enter into my meaning;-no, that blessed and spontaneous life does not belong to the present cycle of the world, but to the previous one, in which God superintended the whole revolution of the universe; and the several parts the universe were distributed under the rule. certain inferior deities, as is the way in some places still There were demigods, who were the shepherds of the various species and herds of animals, and each one was in all respects sufficient for those of whom he was the shepherd; neither was there any violence, or devouring of one another or war or quarrel among them; and I might tell of ten thousand other blessings, which belonged to that dispensation. The reason why the life of man was, as tradition says, spontaneous, is as follows: In those days God himself was their shepherd, and ruled over them, just as man, over them, who is by comparison a divine being, still rules over the lower animals. Under him there were no forms of government or separate possession of women and children; for all men rose again from the earth, having no memory, of the past. And although they had nothing of this sort, the earth gave them fruits in abundance, which grew on trees and shrubs unbidden, and were not planted by the hand of man. And they dwelt naked, and mostly in the open air, for the temperature of their seasons, was mild; and they had no beds, but lay on Soft couches of grass, which grew plentifully out of: the earth. Such was the life of man in the days of Cronos, Socrates; the character of our present life which is said to be under Zeus, you know from your own experience. Can you, and will you, determine which of them you deem the happier?
Y. Soc. Impossible.
Str. Then shall I determine for you as well as I can?
Y. Soc. By all means.
Str. Suppose that the nurslings of Cronos, having this boundless leisure, and the power of holding intercourse, not only with men, but with the brute creation, had used all these advantages with a view to philosophy, conversing with the brutes as well as with one another, and learning of every nature which was gifted with any special power, and was able to contribute some special experience to the store of wisdom there would be no difficulty in deciding that they would be a thousand times happier than the men of our own day. Or, again, if they had merely eaten and drunk until they were full, and told stories to one another and to the animals - such stories as are now attributed to them-in this case also, as I should imagine, the answer would be easy. But until some satisfactory witness can be found of the love of that age for knowledge and: discussion, we had better let the matter drop, and give the reason why we have unearthed this tale, and then we shall be able to get on.
In the fulness of time, when the change was to take place, and the earth-born race had all perished, and every soul had completed its proper cycle of births and been sown in the earth her appointed number of times, the pilot of the universe let the helm go, and retired to his place of view; and then Fate and innate desire reversed the motion of the world. Then also all the inferior deities who share the rule of the supreme power, being informed of what was happening, let go the parts of the world which were under their control. And the world turning round with a sudden shock, being impelled in an opposite direction from beginning to end, was shaken by a mighty earthquake, which wrought a new destruction of all manner of animals. Afterwards, when sufficient time had elapsed, the tumult and confusion and earthquake ceased, and the universal creature, once more at peace attained to a calm, and settle down into his own orderly and accustomed course, having the charge and rule of himself and of all the creatures which are contained in him, and executing, as far as he remembered them, the instructions of his Father and Creator, more precisely at first, but afterwords with less exactness. The reason of the falling off was the admixture of matter in him; this was inherent in the primal nature, which was full of disorder, until attaining to the present order. From God, the constructor; the world received all that is good in him, but from a previous state came elements of evil and unrighteousness, which, thence derived, first of all passed into the world, and were then transmitted to the animals. While the world was aided by the pilot in nurturing the animals, the evil was small, and great the good which he produced, but after the separation, when the world was let go, at first all proceeded well enough; but, as time went there was more and more forgetting, and the old discord again held sway and burst forth in full glory; and at last small was the good, and great was the admixture of evil, and there was a danger of universal ruin to the world, and the things contained in him. Wherefore God, the orderer of all, in his tender care, seeing that the world was in great straits, and fearing that all might be dissolved in the storm and disappear in infinite chaos, again seated himself at the helm; and bringing back the elements which had fallen into dissolution and disorder to the motion which had prevailed under his dispensation, he set them in order and restored them, and made the world imperishable and immortal.
And this is the whole tale, of which the first part will suffice to illustrate the nature of the king. For when the world turned towards the present cycle of generation, the age of man again stood still, and a change opposite to the previous one was the result. The small creatures which had almost disappeared grew in and stature, and the newly-born children of the earth became grey and died and sank into the earth again. All things changed, imitating and following the condition of the universe, and of necessity agreeing with that in their mode of conception and generation and nurture; for no animal; was any longer allowed to come into being in the earth through the agency of other creative beings, but as the world was ordained to be the lord of his own progress, in like manner the parts were ordained to grow and generate and give nourishment, as far as they could, of themselves, impelled by a similar movement. And so we have arrived at the real end of this discourse; for although there might be much to tell of the lower animals, and of the condition out of which they changed and of the causes of the change, about men there is not much, and that little is more to the purpose. Deprived of the care of God, who had possessed and tended them, they were left helpless and defenceless, and were torn in pieces by the beasts, who were naturally fierce and had now grown wild. And in the first ages they were still without skill or resource; the food which once grew spontaneously had failed, and as yet they knew not how to procure it, because they-had never felt the pressure of necessity. For all these reasons they were in a great strait; wherefore also the gifts spoken of in the old tradition were imparted to man by the gods, together with so much teaching and education as was indispensable; fire was given to them by Prometheus, the arts by Hephaestus and his fellow-worker, Athene, seeds and plants by others. From these is derived all that has helped to frame human life; since the care of the Gods, as I was saying, had now failed men, and they had to order their course of life for themselves, and were their own masters, just like the universal creature whom they imitate and follow, ever changing, as he changes, and ever living and growing, at one time in one manner, and at another time in another. Enough of the story, which may be of use in showing us how greatly we erred in the delineation of the king and the statesman in our previous discourse.
