“Now then have you ever seen any thing of this kind with your eyes?” “By no means,” he replied. “Did you ever lay hold of them by any other bodily sense? but I speak generally, as of magnitude, health, strength, and, in a word, of the essence of every thing, that is to say, what each is. Is then the exact truth of these perceived by means of the body, or is it thus, whoever amongst us habituates himself to reflect most deeply and accurately on each several thing about which he is considering, he will make the nearest approach to the knowledge of it?” “Certainly.” 28. “Would not he, then, do this with the utmost purity, who should in the highest degree approach each subject by means of the mere mental faculties, neither employing the sight in conjunction with the reflective faculty, nor introducing any other sense together with reasoning; but who, using pure reflection by itself, should attempt to search out each essence purely by itself, freed as much as possible from the eyes and ears, and, in a word, from the whole body, as disturbing the soul, and not suffering it to acquire truth and wisdom, when it is in communion with it. Is not he the person, Simmias, if any one can, who will arrive at the knowledge of that which is?” 29. “You speak with wonderful truth, Socrates,” replied Simmias. “Wherefore,” he said, “it necessarily follows from all this, that some such opinion as this should be entertained by genuine philosophers, so that they should speak among themselves as follows: ‘A by-path, as it were, seems to lead us on in our researches undertaken by reason,’ because as long as we are encumbered with the body, and our soul is contaminated with such an evil, we can never fully attain to what we desire; and this, we say, is truth. For the body subjects us to innumerable hindrances on account of its necessary support, and moreover if any diseases befal us, they impede us in our search after that which is; and it fills us with longings, desires, fears, all kinds of fancies, and a multitude of absurdities, so that, as it is said in real truth, by reason of the body it is never possible for us to make any advances in wisdom. 30. “For nothing else but the body and its desires occasion wars, seditions, and contests; for all wars amongst us arise on account of our desire to acquire wealth; and we are compelled to acquire wealth on account of the body, being enslaved to its service; and consequently on all these accounts we are hindered in the pursuit of philosophy. But the worst of all is, that if it leaves us any leisure, and we apply ourselves to the consideration of any subject, it constantly obtrudes itself in the midst of our researches, and occasions trouble and disturbance, and confounds us so that we are not able by reason of it to discern the truth. It has then in reality been demonstrated to us, that if we are ever to know any thing purely, we must be separated from the body, and contemplate the things themselves by the mere soul.
