In the following pages I will endeavour to give a short resume of this story, though I am painfully aware of the fact that such an analysis can scarcely do justice to the beauty of the language nor to the wealth of philosophical thought and speculation represented therein.

From the outset the atmosphere is created with broad and happy touches.

On an Island in the Indian Ocean, famous for its health-giving atmosphere, abounding in fruits and inhabitants, Hayy Ibn Yokdhan comes into this world, as the son of a Princess, who is compelled to expose the child soon after his birth. The tide carries him to another Island, where he is found by a roe, that takes pity on him, nurses him like a mother, and watches over his every movement with tender affection.

Under her care he quickly develops into a fine strapping boy who is not afraid to venture a passage with wild beasts that dare to oppose him.

After the death of the roe, at which he is grief-stricken, he is wholly thrown on his own resources. Yet he knows how to look after himself. He covers himself with leaves of trees, and finds out other ways to keep himself warm and protected.

As the repairing of the coverings of leaves was very troublesome, he had a design of taking the tail of some dead beast and wearing it himself; but when he perceived that all beasts avoided those which were dead of the same kind, it made him doubt whether it was safe or not. At last, by chance he found a dead eagle, and observing that none of the beasts showed any aversion to that carcase, he concluded that this would suit his purpose, and so he cuts off the wings, the tail, and spreads the feathers open: then he draws off the skin and divides it into two equal parts, one of which he wears upon his back; with the other he covers his breast: the tail he wore behind and the wings were placed upon each arm.

This dress answered different ends: for in the first place it covered his nakedness, helped to keep him warm, and then it made him so frightful to the beasts that none of them cared to meddle with him or come near him.

After awhile he began to make experiments with the body of the roe, anxious to find out its composition.

He noticed, when he shut his eyes or held anything before him, he could see nothing at all till this obstacle was removed; and so, when he put his fingers in his ears that he could not hear till he took them out again. From which he concluded that all his senses and actions were liable to obstacles and impediments, upon the removal of which the same functions returned to their former course.

Now, when he found no visible defect in the external parts of the body of the roe, and yet at the same time perceived a universal cessation of its motions, he began to imagine that the hurt from which the roe had died was hidden in the inward part of the body.

Now he had observed on the bodies of wild beasts and other animals that all their members were solid, and that there were only three cavities, viz. the skull, the breast, and belly. He imagined, therefore, that the part the nature of which he wanted to find out must be in one of these cavities, and he had a strong persuasion that it was in the middlemost of them.

And having by this way of reasoning assured himself that the disaffected part lay in the breast, he resolved to open the breast of the roe; and, providing himself with sharp flints and splinters of dry cane almost like knives, he made an incision between the ribs, and, cutting through the flesh, came to the Diaphragm.

When he found this tough and not easily broken, he assured himself that such a covering must belong to that part for which he was looking out. After great efforts he succeeded in breaking through, and the first part he met was the lungs ; and at last he found the heart, which he saw closed with a very strong cover and fastened with strong ligaments and guarded with a membrane.

On finding the same membrane on the inside of the ribs, and the lungs in the same posture as on the other side which he had opened first, he concluded the heart to be the part he looked for. When, however, he found that the being which had dwelt there before, had left its house before it fell to ruin, and forsaken it, the whole body seemed to him an inconsiderable thing.

Then his mind was perplexed with a variety of thoughts as to its substance and subsistence, the reason of its departure, etc. After much deliberation, at last he found that from that part of the heart which had departed proceeded all those actions by which the roe had shown her care of him and her affection, - that the body was only as an instrument or tool, like his cudgel with which he used to fight with the wild beasts. Thus all his regard for the body was over and transferred to that by which the body is governed, and by whose power it moves. So he decides in the end to bury the body.

After its burial, the impression of his loneliness and of his dependence upon himself being deepened, he quickly develops his faculties. In a short time he becomes an expert in different sports, as hunting and fishing. He makes himself clothes and shoes of the skins of wild beasts. By the observations he made upon the swallows' nests, being taught the art of building, he builds with his hands a room for his own use, a store-house, and a pantry. Then he contrives to make some wild horses so tractable that he can use them for riding, which is a great help to him in his expeditions and excursions.

His material existence thus once firmly established and secured, he begins to indulge in his speculations on all sorts of bodies, - on the different kinds of animals, plants, minerals and different sorts of stones, earth, water, exhalations and vapours, ice, snow, hail, smoke, fire, etc.

By the time he attains to the age of twenty-eight (fourth Septenary), his mind starts to ponder over astronomical problems - over heaven and stars, sun and moon; and in the end comes to the conclusion that the body of heaven is finite and is of a spherical figure.
