SOC. Not at all, being the man I am; but I might if I were a real reasoner; if such a man were present at this moment he would tell us to refrain from these terms, and would criticize my talk scathingly. But since we are poor creatures, shall I venture to say what the nature of knowing is? For it seems to me that would be of some advantage. THEAET. Venture it then, by Zeus. You shall have full pardon for not refraining from those terms. SOC. Have you heard what they say nowadays that knowing is? THEAET. Perhaps; however, I don’t remember just at this moment. SOC. They say it is having knowledge. THEAET. True. SOC. Let us make a slight change and say possessing knowledge. THEAET. Why, how will you claim that the one differs from the other? SOC. Perhaps it doesn’t; but first hear how it seems to me to differ, and then help me to test my view. THEAET. I will if I can. SOC. Well, then, having does not seem to me the same as possessing. For instance, if a man bought a cloak and had it under his control, but did not wear it, we should certainly say, not that he had it, but that he possessed it. THEAET. And rightly. SOC. Now see whether it is possible in the same way for one who possesses knowledge not to have it, as, for instance, if a man should catch wild birds—pigeons or the like—and should arrange an aviary at home and keep them in it, we might in a way assert that he always has them because he possesses them, might we not? THEAET. Yes. SOC. And yet in another way that he has none of them, but that he has acquired power over them, since he has brought them under his control in his own enclosure,
 
to take them and hold them whenever he likes, by catching whichever bird he pleases, and to let them go again; and he can do this as often as be sees fit. THEAET. That is true. SOC. Once more, then, just as a while ago we contrived some sort of a waxen figment in the soul, so now let us make in each soul an aviary stocked with all sorts of birds, some in flocks apart from the rest, others in small groups, and some solitary, flying hither and thither among them all. THEAET. Consider it done. What next? SOC. We must assume that while we are children this receptacle is empty, and we must understand that the birds represent the varieties of knowledge. And whatsoever kind of knowledge a person acquires and shuts up in the enclosure, we must say that he has learned or discovered the thing of which this is the knowledge, and that just this is knowing. THEAET. So be it.
