On the other hand, an artificial education is having one's head crammed full of ideas, derived from hearing others talk, from learning and reading, before one has anything like an extensive knowledge of the world as it is and as one sees it. The observations which produce all these ideas are said to come later on with experience; but until then these ideas are applied wrongly, and accordingly both things and men are judged wrongly, seen wrongly, and treated wrongly. And so it is that education perverts the mind; and this is why, after a long spell of learning and reading, we enter the world, in our youth, with views that are partly simple, partly perverted; consequently we comport ourselves with an air of anxiety at one time, at another of presumption. This is because our head is full of ideas which we are now trying to make use of, but almost always apply wrongly. This is the result of ὑστερον προτερον (putting the cart before the horse), since we are directly opposing the natural development of our mind by obtaining ideas first and observations last; for teachers, instead of developing in a boy his faculties of discernment and judgment, and of thinking for himself, merely strive to stuff his head full of other people's thoughts. Subsequently, all the opinions that have sprung from misapplied ideas have to be rectified by a lengthy experience; and it is seldom that they are completely rectified. This is why so few men of learning have such sound common sense as is quite common among the illiterate. * * * * * From what has been said, the principal point in education is that _one's knowledge of the world begins at the right end;_ and the attainment of which might be designated as the aim of all education. But, as has been pointed out, this depends principally on the observation of each thing preceding the idea one forms of it; further, that narrow ideas precede broader; so that the whole of one's instruction is given in the order that the ideas themselves during formation must have followed. But directly this order is not strictly adhered to, imperfect and subsequently wrong ideas spring up; and finally there arises a perverted view of the world in keeping with the nature of the individual--a view such as almost every one holds for a long time, and most people to the end of their lives. If a man analyses his own character, he will find that it was not until he reached a very ripe age, and in some cases quite unexpectedly, that he was able to rightly and clearly understand many matters of a quite simple nature.
