4. And for this reason, if the apparatus of the organs of sense should be closed and sleep hindered by some occupation, the nervous system, becoming filled with the vapours, is naturally and spontaneously extended so that the part which has had its density increased by the vapours is rarefied by the process of extension, just as those do who squeeze the water out of clothes by vehement wringing: and, seeing that the parts about the pharynx are somewhat circular, and nervous tissue abounds there, whenever there is need for the expulsion from that part of the density of the vapours--since it is impossible that the part which is circular in shape should be separated directly, but only by being distended in the outline of its circumference--for this reason, by checking the breath in a yawn the chin is moved downwards so as to leave a hollow to the uvula, and all the interior parts being arranged in the figure of a circle, that smoky denseness which had been detained in the neighbouring parts is emitted together with the exit of the breath. And often the like may happen even after sleep when any portion of those vapours remains in the region spoken of undigested and unexhaled.
5. Hence the mind of man clearly proves its claim [1639] to connection with his nature, itself also co-operating and moving with the nature in its sound and waking state, but remaining unmoved when it is abandoned to sleep, unless any one supposes that the imagery of dreams is a motion of the mind exercised in sleep. We for our part say that it is only the conscious and sound action of the intellect which we ought to refer to mind; and as to the fantastic nonsense which occurs to us in sleep, we suppose that some appearances of the operations of the mind are accidentally moulded in the less rational part of the soul; for the soul, being by sleep dissociated from the senses, is also of necessity outside the range of the operations of the mind; for it is through the senses that the union of mind with man takes place; therefore when the senses are at rest, the intellect also must needs be inactive; and an evidence of this is the fact that the dreamer often seems to be in absurd and impossible situations, which would not happen if the soul were then guided by reason and intellect.
6. It seems to me, however, that when the soul is at rest so far as concerns its more excellent faculties (so far, I mean, as concerns the operations of mind and sense), the nutritive part of it alone is operative during sleep, and that some shadows and echoes of those things which happen in our waking moments--of the operations both of sense and of intellect--which are impressed upon it by that part of the soul which is capable of memory, that these, I say, are pictured as chance will have it, some echo of memory still lingering in this division of the soul.
[1639] Reading deiknusin, as Forbes does (apparently from all the mss. and agreeing with the earlier editt.). The Latin translation points to the reading deiknutai
