'So the case was doubtful, and had opinion on both sides. [So the philosopher on the mountain tells us, too, for his common-place book and this author's happen to be the same.] Again we see when M. Brutus and Cassius _invited to a supper_ certain _whose opinions they meant to feel_, whether they were fit to be made their associates, and cast forth the question touching the killing of a tyrant,--being an usurper,--_they were divided in opinion_;' [this of itself is a very good specimen of the style in which points are sometimes introduced casually in passing, and by way of illustration merely] some holding that _servitude_ was the _extreme_ of evils, and _others_ that tyranny was _better than a civil war_; and this question also our philosopher of the mountain has considered very carefully from his retreat, weighing all the _pros_ and _cons_ of it. And it is a question which was treated also, as we all happen to know, in that other form of writing for which this author expresses so decided a preference, in which the art of the poet is brought in to enforce and impress the conclusion of the philosopher. Indeed, as we proceed further with the plan of this so radical part of the subject, we shall find, that the ground indicated has everywhere been taken up on the spot by somebody, and to purpose. CHAPTER IV. THE SCIENCE OF MORALITY. Section II.--THE HUSBANDRY THEREUNTO; OR, THE CURE AND CULTURE OF THE MIND. 'Tis an unweeded garden That grows to seed--' Hamlet. But we have finished now with what he has to say here of the EXEMPLAR or science of GOOD, and its _kinds_, and _degrees_, and the comparison of them, the good that is proper to the individual, and the good that includes society. He has found much fine work on that platform of virtue, and felicity,--excellent exemplars, the purest doctrine, the loftiest virtue, tried by the scientific standard. And though he has gone behind those popular names of vice and virtue, pain and pleasure, and the like, in which these doctrines _begin_, to the more simple and original forms, which the doctrine of nature in general and its laws supplies, for a platform of moral science, his doctrine is large enough to include all these works, in all their excellence, and give them their true place. A reviewer so discriminating, then, so far from that disposition to scorn and censure, which he reprehends, so careful to conserve that which is good in his scientific constructions and reformations, so pure in judgment in discovering and severing that which is corrupt, a reporter so clearly scientific, who is able to maintain through all this astounding report of the deficiences in human learning, a tone so quiet, so undemonstrative, such a one deserves the more attention when he comes now to 'the art and practic part' of this great science, to which all other sciences are subordinate, and declares to us that he finds it, as a part of science, 'WANTING!' not defective, but _wanting_.
