Locke's definition of knowledge.

particular result, and (3) must have before it all the data necessary for forming a judgment. In practice these conditions are seldom (if ever) fulfilled; and Locke himself, when he wants an instance of a mind that can acquiesce in the certainty of its conclusions, takes it from "angels and separate spirits who may be endowed with more comprehensive faculties" than we are (C. of U. § iij, 3).

§ 5. It seems to me then that Locke much exaggerates the power of the individual reason for getting at the truth. And to exaggerate the importance of one function of the mind is to unduly diminish the importance of the rest. Thus we find that in Locke's scheme of education little thought is taken for the play of the affections and feelings; and as for the imagination it is treated merely as a source of mischief.

§ 6. Locke, as it has often been pointed out, differs from the schoolmaster in making small account of the knowledge to be acquired by those under education. But it has not been so often remarked that the fundamental difference is much deeper than this and lies in the conception of knowledge itself. With the ordinary schoolmaster the test of knowledge is the power of reproduction. Whatever

pupils can reproduce with difficulty they know imperfectly; whatever they can reproduce with ease they know thoroughly. But Locke's definition of knowledge confines it to a much smaller area. According to him knowledge is "the internal perception of the mind" (Locke to Stillingfleet v. F. B. ij, 432). "Knowing is seeing; and if it be so, it is madness to persuade ourselves we do so by another man's eyes, let him use never so many words to tell us that what he asserts is very visible. Till we ourselves see it with our own eyes, and perceive it by our own understandings, we are as much

Knowing without seeing.

in the dark and as void of knowledge as before, let us believe any learned authors as much as we will" (C. of U. § 24).*

§ 7. Here Locke makes no distinction between different classes of truths. But surely very important differences exist.

About some physical facts our knowledge is at once most certain and most definite when we derive it through the evidence of our own senses. 66 Seeing is believing," says the proverb. It may be believing, but it is not knowing. That certainty which we call knowledge we often arrive at better by the testimony of others than by that of our

own senses.

Miss Martineau in her Autobiography tells us that as a child of ten she entirely and unaccountably failed to see a comet which was visible to all other people; but, although her own senses were at fault, the evidence for the comet was so conclusive that she may be said to have known there was a comet in the sky.

Compare Carlyle ::- Except thine own eye have got to see it, except thine own soul have victoriously struggled to clear vision and belief of it, what is the thing seen or the thing believed by another or by never so many others? Alas, it is not thine, though thou look on it, brag about it, and bully and fight about it till thou die, striving to persuade thyself and all men how much it is thine! Not it is thine, but only a windy echo and tradition of it bedded [an echo bedded?] in hypocrisy, ending sure enough in tragical íutility is thine." Froude's Thos. Carlyle, ij, 10. Similarly Locke wrote to Bolde in 1699:-" To be learned in the lump by other men's thoughts, and to be right by saying after others is much the easier and quieter way; but how a rational man that should enquire and know for himself can content himself with a faith or religion taken upon trust, or with such a servile submission of his understanding as to admit all and nothing else but what fashion makes passable among men, is to me astonishing." Quoted by Fowler, Locke, p. 118.

Discentem credere oportet.

On sufficient evidence we can know anything, just as we know there is a great water-fall at Niagara though we may never have crossed the Atlantic. But we cannot be so certain simply on the evidence of our senses. If we trusted entirely to them we might take the earth for a plane and "know" that the sun moved round it.

§ 8. But Locke probably considers as the subject of knowledge not so much physical facts as the great body of truths which are ascertained by the intellect. It is the eye of the mind by which alone knowledge is to be gained. Of these truths the purest specimens are the truths of geometry. It may be said that only those who have followed the proofs know that the area of the square on the side opposite the right angle in a right-angled triangle is equal to the sum of the squares on the other sides. But even in pure reasoning like this, the tiro often seems to see what he does not really see; and where his own reason brings him to a conclusion different from the one established he knows only that he is mistaken.

§ 9. It must be admitted then that first-hand knowledge, knowledge derived from the vision of the eye or of the mind, is not the only knowledge the young require. Every learner must take things on trust, as even Lord Bacon admits. Discentem credere oportet. To use Locke's own words :-"I do not say, to be a good geographer that a man should visit every mountain, river, promontory, and creek upon the face of the earth, view the buildings and survey the land everywhere as if he were going to make a purchase" (C. of U., iij, ad f.). So that even according to Locke's own shewing we must use the eyes of others as well as our own, and this is true not in geography only, but in all other branches of knowledge.

L.'s "Knowledge" and the schoolmaster's.

§ 10. But are we driven to the alternative of agreeing either with Locke or with the schoolmaster? I do not see that we are. The thought which underlies Locke's system of education is this: true knowledge can be acquired only by the exercise of the reason: in childhood the reasoning power is not strong enough for the pursuit of knowledge : knowledge, therefore, is out of the question at that age, and the only thing to be thought of is the formation of habits. Opposed to this we have the schoolmaster's ideal which is governed by examinations. According to this ideal the object of the school course is to give certain “knowledge," linguistic and other, and to fix it in the memory in such a manner that it can be displayed on the day of examination. "Knowledge" of this kind often makes no demand whatever on the reasoning faculty, or indeed on any faculty but that of remembering and reproducing what the learner has been told; in extreme cases the memory of mere sounds or symbols suffices.

But after all we are not compelled to choose between these two theories. Take, e.g., the subject which Locke has mentioned, geography. The schoolmasters of the olden time began with the use of the globes, a plan which, by the way, Locke himself seems to have winked at. His disciple Molyneux tells him of the performances of the small Molyneux. When he was but just turned five he could read perfectly well, and on the globe could have traced out and pointed at all the noted ports, countries, and cities of the world, both land and sea; by five and a half could perform many of the plainest problems on the globe, as the longitude and latitude, the Antipodes, the time with them and other countries, &c. (Molyneux to L., 24th August, 1695.) Here we find a child brought up, without any

"Knowledge" in Geography.

protest from Locke, on mere examination knowledge, which according to Locke himself is not knowledge at all. It is strange that Locke did not at once point out to Moly. neux that the child was not really learning what the father supposed him to be learning. When the child turned over the plaster ball and found the word "Paris," the father no doubt attributed to the child much that was in his own mind only. To the child "the Globe" (as Rousseau afterwards said), was nothing but a plaster ball; "Paris was nothing but some letters marked on that ball. Comenius had already got a notion how children may be given some knowledge of geography. "Children begin geography," said he, "when they get to understand what a hill, a valley, a field, a river, a village, a town is." (Supra, p. 145.) When this beginning has been made, geographical knowledge is at once possible to the child, and not before.

Perfect knowledge in geography, as in most other things, is out of every one's reach. Nobody knows, e.g., all that could be known about Paris. The knowledge its inhabitants have of it is very various, but in all cases this knowledge is far greater than that of a visitor. The visitor's

knowledge again is far greater than that of strangers who have never seen Paris. Nobody, then, can know everything even about Paris; but a child who knows what a large town is, and can fancy to himself a big town called Paris, which is the biggest and most important town in France has some knowledge about it. This must be maintained against Locke. Against the schoolmaster it may be pointed out that making an Eskimo say the words :-"Paris is the capital of France," would not be giving him any knowledge at all; and the same may be said of many "lessons" in
