What are the new senses enjoyed by the superhuman being? It would be impossible to return a satisfactory reply to this question. We have no knowledge of any other senses than those with which we ourselves are endowed, and no amount of genius could enable any man to divine the object of a sense denied to him by nature. Try to give a man born blind an idea of the colour, red; and he will answer: "Yes, I understand! It is piercing, like the sound of a trumpet!" Try to give a man born deaf an idea of the sound of the harp, and he will answer: "Yes! It is gentle and tender, like the green grass of the fields!" Let us renounce, once for all, any attempt to define the senses with which nature endows the beings who people the ethereal plains; these senses belong to objects and ideas the mere notion of which is forbidden to us. There is a well-known story of a man born blind, upon whom the famous surgeon Childesen operated. Having recovered his sight, the patient was a long time learning the use of his eyes; he was obliged to educate those organs, step by step, and by slow degrees to form his intelligence. Equally well known is Condillac's beautiful fiction, in which he imagines a man born into the world without the senses of sight, speech, and hearing, and who is, therefore, destitute of ideas. By degrees, he is endowed with each of these senses, and the philosopher thus composes, bit by bit, a soul which feels, and a mind which thinks. This philosophical idea has been greatly admired. Like the man-statue of Condillac, we are only, while here below, imperfect statues, endowed with but a small number of senses. When, however, we shall have reached the superior regions destined to our ennobled condition, we shall be put in possession of new senses, such as our reason dimly perceives, and our hearts long for. We cannot, as we have previously said, divine what the new senses which shall be granted to the superhuman being are to be, because they belong to objects and ideas of which we are ignorant, and to forms which are exclusively proper to worlds at present hidden from our eyes. The kingdom of the planetary ether has its geography, its powers, its passions, and its laws; and the new senses of men, resuscitated to that glorious existence, will be exercised upon those objects. The only thing which we can safely prognosticate is that all the senses which we now possess will then exist in their full perfection--sight, hearing, touch, taste, and smell. It is allowable to deduce this process of future perfection by reasoning from the extraordinary development of certain senses in the case of animals.
