Bentham [7]
This method Bentham has finally installed in philosophy; has made it henceforth imperative on philosophers of all schools. By it he has formed the intellects of many thinkers, who either never adopted, or have abandoned, many of his peculiar opinions. He has taught the method to men of the most opposite schools to his; he has made them perceive that if they do not test their doctrines by the method of detail, their adversaries will. He has thus, it is not too much to say, for the first time introduced precision of thought into moral and political philosophy. Instead of taking up their opinions by intuition, or by ratiocination from premises adopted on a mere rough view, and couched in language so vague that it is impossible to say exactly whether they are true or false, philosophers are now forced to understand one another, to break down the generality of their propositions, and join a precise issue in every dispute. This is nothing less than a revolution in philosophy. Its effect is gradually becoming evident in the writings of English thinkers of every variety of opinion, and will be felt more and more in proportion as Bentham's writings are diffused, and as the number of minds to whose formation they contribute is multiplied. It will naturally be presumed that of the fruits of this great philosophical improvement some portion at least will have been reaped by its author. Armed with such a potent instrument, and wielding it with such singleness of aim; cultivating the field of practical philosophy with such unwearied and such consistent use of a method right in itself, and not adopted by his predecessors; it cannot he but that Bentham by his own inquiries must have accomplished something considerable. And so, it will be found, he has; something not only considerable, but extraordinary; though but little compared with what he has left undone, and far short of what his sanguine and almost boyish fancy made him flatter himself that he had accomplished. His peculiar method, admirably calculated to make clear thinkers, and sure ones to the extent of their materials, has not equal efficacy for making those materials complete. It is a security for accuracy, but not for comprehensiveness; or rather, it is a security for one sort of comprehensiveness, but not for another. Bentham's method of laying out his subject is admirable as a preservative against one kind of narrow and partial views. He begins by placing before himself the whole of the field of inquiry to which the particular question belongs, and divides down till he arrives at the thing he is in search of; and thus by successively rejecting all which is not the thing, he gradually works out a definition of what it is. This, which he calls the exhaustive method, is as old as philosophy itself. Plato owes everything to it, and does everything by it; and the use made of it by that great man in his Dialogues, Bacon, in one of those pregnant logical hints scattered through his writings, and so much neglected by most of his pretended followers, pronounces to be the nearest approach to a true inductive method in the ancient philosophy. Bentham was probably not aware that Plato had anticipated him in the process to which he too declared that he owed everything. By the practice of it, his speculations are rendered eminently systematic and consistent; no question, with him, is ever an insulated one; he sees every subject in connexion with all the other subjects with which in his view it is related, and from which it requires to be distinguished; and as all that he knows, in the least degree allied to the subject, has been marshalled in an orderly manner before him, he does not, like people who use a looser method, forget and overlook a thing on one occasion to remember it on another. Hence there is probably no philosopher of so wide a range, in whom there are so few inconsistencies. If any of the truths which he did not see, had come to be seen by him, he would have remembered it everywhere and at all times, and would have adjusted his whole system to it. And this is
