Mr. Gladstone pronounces the right of private judgment, as it is generally understood throughout Protestant Europe, to be a monstrous abuse. He declares himself favourable, indeed, to the exercise of private judgment, after a fashion of his own. We have, according to him, a right to judge all the doctrines of the Church of England to be sound, but not to judge any of them to be unsound. He has no objection, he assures us, to active inquiries into religious questions. On the contrary, he thinks such inquiry highly desirable, as long as it does not lead to diversity of opinion; which is much the same thing as if he were to recommend the use of fire that will not burn down houses, or of brandy that will not make men drunk. He conceives it to be perfectly possible for mankind to exercise their intellects vigorously and freely on theological subjects, and yet to come to exactly the same conclusions with each other and with the Church of England. And for this opinion he gives, as far as we have been able to discover, no reason whatever, except that everybody who vigorously and freely exercises his understanding on Euclid’s Theorems assents to them. “The activity of private judgment,” he truly observes, “and the unity and strength of conviction in mathematics {163}vary directly as each other.” On this unquestionable fact he constructs a somewhat questionable argument. Everybody who freely inquires agrees, he says, with Euclid. But the Church is as much in the right as Euclid. Why, then, should not every free inquirer agree with the Church? We could put many similar questions. Either the affirmative or the negative of the proposition that King Charles wrote the _Icon Basilike_ is as true as that two sides of a triangle are greater than the third side. Why, then, do Dr. Wordsworth and Mr. Hallam agree in thinking two sides of a triangle greater than the third side, and yet differ about the genuineness of the _Icon Basilike_? The state of the exact sciences proves, says Mr. Gladstone, that, as respects religion “the association of these two ideas, activity of inquiry, and variety of conclusion, is a fallacious one.” We might just as well turn the argument the other way, and infer from the variety of religious opinions that there must necessarily be hostile mathematical sects, some affirming, and some denying, that the square of the hypothenuse is equal to the squares of the sides. But we do not think either the one analogy or the other of the smallest value. Our way of ascertaining the tendency of free inquiry is simply to open our eyes and look at the world in which we live; and there we see that free inquiry on mathematical subjects produces unity, and that free inquiry on moral subjects produces discrepancy. There would undoubtedly be less discrepancy if inquirers were more diligent and candid. But discrepancy there will be among the most diligent and candid, as long as the constitution of the human mind, and the nature of moral evidence,
