Bentham has been in this age and country the great questioner of things established. It is by the influence of the modes of thought with which his writings inoculated a considerable number of thinking men, that the yoke of authority has been broken, and innumerable opinions, formerly received on tradition as incontestable, are put upon their defence, and required to give an account of themselves. Who, before Bentham (whatever controversies might exist on points of detail) dared to speak disrespectfully, in express terms, of the British Constitution, or the English Law? He did so; and his arguments and his example together encouraged others. We do not mean that his writings caused the Reform Bill, or that the Appropriation Clause owns him as its parent: the changes which have been made, and the greater changes which will be made, in our institutions, are not the work of philosophers, but of the interests and instincts of large portions of society recently grown into strength. But Bentham gave voice to those interests and instincts: until he spoke out, those who found our institutions unsuited to them did not dare to say so, did not dare consciously to think so; they had never heard the excellence of those institutions questioned by cultivated men, by men of acknowledged intellect; and it is not in the nature of uninstructed minds to resist the united authority of the instructed. Bentham broke the spell. It was not Bentham by his own writings; it was Bentham through the minds and pens which those writings fed -- through the men in more direct contact with the world, into whom his spirit passed. If the superstition about ancestorial wisdom has fallen into decay; if the public are grown familiar with the idea that their laws and institutions are in great part not the product of intellect and virtue, but of modern corruption grafted upon ancient barbarism;if the hardiest innovation is no longer scouted because it is an innovation -- establishments no longer considered sacred because they are establishments -- it will be found that those who have accustomed the public mind to these ideas have learnt them in Bentham's school, and that the assault on ancient institutions has been, and is, carried on for the most part with his weapons.
It matters not although these thinkers, or indeed thinkers of any deion, have been but scantily found among the persons prominently and ostensibly at the head of the Reform movement.
All movements, except directly revolutionary ones, are headed, not by those who originate them, but by those who know best how to compromise between the old opinions and the new. The father of English innovation both in doctrines and in institutions, is Bentham: he is the great subversive, or, in the language of continental philosophers, the great critical, thinker of his age and country.
We consider this, however, to be not his highest title to fame. Were this all, he were only to be ranked among the lowest order of the potentates of mind -- the negative, or destructive philosophers; those who can perceive what is false, but not what is true; who awaken the human mind to the inconsistencies and absurdities of time-sanctioned opinions and institutions, but substitute nothing in the place of what they take away. We have no desire to undervalue the services of such persons: mankind have been deeply indebted to them; nor will there ever be a lack of work for them, in a world in which so many false things are believed, in which so many which have been true, are believed long after they have ceased to be true. The qualities, however, which fit men for perceiving anomalies, without perceiving the truths which would rectify them, are not among the rarest of endowments. Courage, verbal acuteness, command over the forms of argumentation, and a popular style, will make, out of the shallowest man, with a sufficient lack of reverence, a considerable negative philosopher. Such men have never been wanting in periods of culture; and the period in which Bentham formed his early impressions was emphatically their reign, in proportion to its barrenness in the more noble products of the human mind. An age of formalism in the Church and corruption in the State, when the most valuable part of the meaning of traditional doctrines had faded from the minds even of those who retained from habit a mechanical belief in them, was the time to raise up all kinds of sceptical philosophy. Accordingly, France had Voltaire, and his school of negative thinkers, and England (or rather Scotland) had the profoundest negative thinker on record, David Hume: a man, the peculiarities of whose mind qualified him to detect failure of proof, and want of logical consistency, at a depth which French sceptics, with their comparatively feeble powers of analysis and abstractions stop far short of, and which German subtlety alone could thoroughly appreciate, or hope to rival.
If Bentham had merely continued the work of Hume, he would scarcely have been heard of in philosophy. for he was far inferior to Hume in Hume's qualities, and was in no respect fitted to excel as a metaphysician. We must not look for subtlety, or the power of recondite analysis, among his intellectual characteristics. In the former quality, few great thinkers have ever been so deficient; and to find the latter, in any considerable measure, in a mind acknowledging any kindred with his, we must have recourse to the late Mr. Mill -- a man who united the great qualities of the metaphysicians of the eighteenth century, with others of a different complexion, admirably qualifying him to complete and correct their work.
Bentham had not these peculiar gifts; but he possessed others, not inferior, which were not possessed by any of his precursors;which have made him a source of light to a generation which has far outgrown their influence, and, as we called him, the chief subversive thinker of an age which has long lost all that they could subvert.
