discussion; and, in order to appreciate it, it will be necessary to revert briefly to a somewhat earlier stage of ecclesiastical history. And in the first place, it may be observed, that the phrase intellectual virtue, which is often used in a metaphorical sense, is susceptible of a strictly literal interpretation. If a sincere and active desire for truth be a moral duty, the discipline and the dispositions that are plainly involved in every honest search fall rigidly within the range of ethics. To love truth sincerely means to pursue it with an earnest, conscientious, unflagging zeal. It means to be prepared to follow the light of evidence even to the most unwelcome conclusions; to labour earnestly to emancipate the mind from early prejudices; to resist the current of the desires, and the refracting influence of the passions; to proportion on all occasions conviction to evidence, and to be ready, if need be, to exchange the calm of assurance for all the suffering of a perplexed and disturbed mind. To do this is very difficult and very painful; but it is clearly involved in the notion of earnest love of truth. If, then, any system stigmatises as criminal the state of doubt, denounces the examination of some one class of arguments or facts, seeks to introduce the bias of the affections into the enquiries of the reason, or regards the honest conclusion of an upright investigator as involving moral guilt, that system is subversive of intellectual honesty.

Among the ancients, although the methods of enquiry were often very faulty, and generalisations very hasty, a respect for the honest search,after truth was widely diffused.1 There were, as we have already seen, instances in which certain religious practices which were regarded as attestations of loyalty, or as necessary to propitiate the gods in favour of

Thus 'indagatio veri' was reckoned among the leading virtues, and the high place given to σopía and 'prudentia ' in ethical writings

preserved the notion of the moral duties connected with the discipline of the intellect.

the State, were enforced by law; there were even a few instances of philosophies, which were believed to lead directly to immoral results or social convulsions, being suppressed; but, as a general rule, speculation was untrammelled, the notion of there being any necessary guilt in erroneous opinion was unknown, and the boldest enquirers were regarded with honour and admiration. The religious theory of Paganism had in this respect some influence. Polytheism, with many faults, had three great merits. It was eminently poetical, eminently patriotic, and eminently tolerant. The conception of a vast hierarchy of beings more glorious than, but not wholly unlike, men, presiding over all the developments of nature, and filling the universe with their deeds, supplied the chief nutriment of the Greek imagination. The national religions, interweaving religious ceremonies and associations with all civic life, concentrated and intensified the sentiment of patriotism, and the notion of many distinct groups of gods led men to tolerate many forms of worship and great variety of creeds. In that colossal amalgam of nations of which Rome became the metropolis, intellectual liberty still further advanced; the vast variety of philosophies and beliefs expatiated unmolested; the search for truth was regarded as an important element of virtue, and the relentless and most sceptical criticism which Socrates had applied in turn to all the fundamental propositions of popular belief remained as an example to his successors.

We have already seen that one leading cause of the rapid progress of the Church was that its teachers enforced their distinctive tenets as absolutely essential to salvation, and thus assailed at a great advantage the supporters of all other creeds which did not claim this exclusive authority. We have seen, too, that in an age of great and growing credulity they had been conspicuous for their assertion of the duty of absolute, unqualified, and unquestioning belief. The notion of the guilt both of error and of doubt grew rapidly, and, being

soon regarded as a fundamental tenet, it determined the whole course and policy of the Church.

And here, I think, it will not be unadvisable to pause for a moment, and endeavour to ascertain what misconceived truth lay at the root of this fatal tenet. Considered abstractedly and by the light of nature, it is as unmeaning to speak of the immorality of an intellectual mistake as it would be to talk of the colour of a sound. If a man has sincerely persuaded himself that it is possible for parallel lines to meet, or for two straight lines to enclose a space, we pronounce his judgment to be absurd; but it is free from all tincture of immorality. And if, instead of failing to appreciate a demonstrable truth, his error consisted in a false estimate of the conflicting arguments of an historical problem, this mistake assuming always that the enquiry was an upright one is still simply external to the sphere of morals. It is possible that his conclusion, by weakening some barrier against vice, may produce vicious consequences, like those which might ensue from some ill-advised modification of the police force; but it in no degree follows from this that the judgment is in itself criminal. If a student applies himself with the same dispositions to Roman and Jewish histories, the mistakes he may make in the latter are no more immoral than those which he may make in the former.

There are, however, two cases in which an intellectual error may be justly said to involve, or at least to represent, guilt. In the first place, error very frequently springs from the partial or complete absence of that mental disposition which is implied in a real love of truth. Hypocrites, or men who through interested motives profess opinions which they do not really believe, are probably rarer than is usually supposed; but it would be difficult to over-estimate the number of those whose genuine convictions are due to the unresisted bias of their interests. By the term interests, I mean not only material well-being, but also all those mental luxuries,

all those grooves or channels for thought, which it is easy and pleasing to follow, and painful and difficult to abandon. Such are the love of ease, the love of certainty, the love of system, the bias of the passions, the associations of the imagination, as well as the coarser influences of social position, domestic happiness, professional interest, party feeling, or ambition. In most men, the love of truth is so languid, and the reluctance to encounter mental suffering is so great, that they yield their judgments without an effort to the current, withdraw their minds from all opinions or arguments opposed to their own, and thus speedily convince themselves of the truth of what they wish to believe. He who really loves truth is bound at least to endeavour to resist these distorting influences, and in as far as his opinions are the result of his not having done so, in so far they represent a moral failing.

In the next place, it must be observed that every moral disposition brings with it an intellectual bias which exercises a great and often a controlling and decisive influence even upon the most earnest enquirer. If we know the character or disposition of a man, we can usually predict with tolerable accuracy many of his opinions. We can tell to what side of politics, to what canons of taste, to what theory of morals he will naturally incline. Stern, heroic, and haughty natures tend to systems in which these qualities occupy the foremost position in the moral type, while gentle natures will as naturally lean towards systems in which the amiable virtues are supreme. Impelled by a species of moral gravitation, the enquirer will glide insensibly to the system which is congruous to his disposition, and intellectual difficulties will seldom arrest him. He can have observed human nature with but little fruit who has not remarked how constant is this connection, and how very rarely men change fundamentally the principles they had deliberately adopted on religious, moral, or even political questions,

without the change being preceded, accompanied, or very speedily followed, by a serious modification of character. So, too, a vicious and depraved nature, or a nature which is hard, narrow, and unsympathetic, will tend, much less by calculation or indolence than by natural affinity, to low and degrading views of human nature. Those who have never felt the higher emotions will scarcely appreciate them. The materials with which the intellect builds are often derived from the heart, and a moral disease is therefore not unfrequently at the root of an erroneous judgment.

Of these two truths the first cannot, I think, be said to have had any influence in the formation of the theological notion of the guilt of error. An elaborate process of mental discipline, with a view to strengthening the critical powers of the mind, is utterly remote from the spirit of theology; and this is one of the great reasons why the growth of an inductive and scientific spirit is invariably hostile to theological interests. To raise the requisite standard of proof, to inculcate hardness and slowness of belief, is the first task of the inductive reasoner. He looks with great favour upon the condition of a suspended judgment; he encourages men rather to prolong than to abridge it; he regards the tendency of the human mind to rapid and premature generalisations as one of its most fatal vices; he desires especially that that which is believed should not be so cherished that the mind should be indisposed to admit doubt, or, on the appearance of new arguments, to revise with impartiality its conclusions. Nearly all the greatest intellectual achievements of the last three centuries have been preceded and prepared by the growth of scepticism. The historic scepticism which Vico, Beaufort, Pouilly, and Voltaire in the last century, and Niebuhr and Lewis in the present century, applied to ancient history, lies at the root of all the great modern efforts to reconstruct the history of mankind. The splendid discoveries of physical science would have been impossible but for the
