In [some] universities the teacher is prohibited from receiving any honorary or fee from his pupils, and his salary constitutes the whole of the revenue which he derives from his office. His interest is, in this case, set as directly in opposition to his duty as it is possible to set it…. It is the interest of every man to live as much at his ease as he can; and if his emoluments are to be precisely the same, whether he does, or does not perform some very laborious duty, it is certainly his interest, at least as interest is vulgarly understood, either to neglect it altogether, or, if he is subject to some authority which will not suffer him to do this, to perform it in as careless and slovenly a manner as that authority will permit. If he is naturally active and a lover of labour, it is his interest to employ that activity in any way, from which he can derive some advantage, rather than in the performance of his duty, from which he can derive none.
If the authority to which he is subject resides in the body corporate, the college, or university, of which he himself is a member, and in which the greater part of the other members are, like himself, persons who either are, or ought to be, teachers; they are likely to make a common cause, to be all very indulgent to one another, and every man to consent that his neighbor may neglect his duty provided he himself is allowed to neglect his own. In the university at Oxford, the greater part of the public professors have, for these many years, given up altogether even the pretence of teaching.
[In a state or religious university a professor will probably not be allowed] to neglect his duty altogether. All that . . . [his] superiors, however, can force him to do, is to attend upon his pupils a certain number of hours, that is, to give a certain number of lectures in the week or in the year. What those lectures shall be, must still depend upon the diligence of the teacher; and that diligence is likely to be proportioned to the motives which he has for exerting it. . . .
If the teacher happens to be a man of sense, it must be an unpleasant thing to him to be conscious, while he is lecturing his students, that he is either speaking or reading nonsense, or what is very little better than nonsense. It must too be unpleasant to him to observe that the greater part of his students desert his lectures; or perhaps attend upon them with plain enough marks of neglect, contempt, and derision. If he is obliged, therefore, to give a certain number of lectures, these motives alone, without any other interest, might dispose him to take some pains to give tolerably good ones. Several different expedients, however, may be fallen upon, which will effectually blunt the edge of all those incitements to diligence. The teacher, instead of explaining to his pupils himself the science in which he proposes to instruct them, may read some book upon it; and if this book is written in a foreign and dead language, by interpreting it to them into their own; or, what would give him still less trouble, by making them interpret it to him, and by now and then making an occasional remark upon it, he may flatter himself that he is giving a lecture. The slightest degree of knowledge and application will enable him to do this, without exposing himself to contempt or derision, or saying anything that is really foolish, absurd, or ridiculous. The discipline of the college, at the same time, may enable him to force all his pupils to the most regular attendance upon this sham-lecture, and to maintain the most decent and respectful behavior during the whole time of the performance.
The discipline of colleges and universities is in general contrived, not for the benefit of the students, but for the interest, or more properly speaking, for the ease of the masters. Its object is, in all cases, to maintain the authority of the master, and whether he neglects or performs his duty, to oblige the students in all cases to behave to him as if he performed it with the greatest diligence and ability. It seems to assume perfect wisdom and virtue in the one order, and the greatest weakness and folly in the other. Where the masters, however, really perform their duty, there are no examples, I believe, that the greater part of the students ever neglect theirs. No discipline is ever requisite to force attendance upon lectures which are really worth the attending, as is well known wherever any such lectures are given.
Force and restraint may, no doubt, be in some degree requisite in order to oblige children, or very young boys, to attend to those parts of education which it is thought necessary for them to acquire during that early period of life; but after twelve or thirteen years of age, provided the master does his duty, force or restraint can scarce ever be necessary to carry on any part of education.
