appearance from the distinctive leafage of its perfect growth; but the type nothing the less is one, and the necessary law of the whole congruous growth lay in the unity of the germ. There is nothing accidental in nature; so neither in morals. All things are necessary; all things are self-consistent; all things are harmonious; all things upon a whole view of the whole are complete. The distinctive character therefore of such an ethical system as Christianity is to be sought not in the fundamental invariable absolute types of right and wrong, which are the same everywhere, but mainly in the following two things--_First_, In its method of operation and in the steam power, the strong convictions and fervid passions by which the moral machinery is set in motion; or, to adopt another simile, in the fountainheads from which the necessary water-courses of a systematic social irrigation are supplied. _Secondly_, In the particular virtues which its method of operation and its moral steam, in conjunction with the nature of the materials acted on, brings on the stage with a certain preference. For though a moral system may, or rather must, include theoretically all {193} the virtues, and is justly blamed if it exclude one, even the smallest, yet from the narrowness of finite natures, and the laws of habit, it seems practically impossible that as soon as any moral system becomes a traditional law for great masses of men, there should not be manifested a strong tendency to put certain virtues into the foreground, while others are left to find their places without favour, or even with a certain amount of discouragement. All soils are not equally favourable to all plants; and the most healthy climates, where human beings of the greatest amount of robustness and grace are produced, have never been free from peculiar diseases, springing from a source indissolubly intertwined with the conditions of their remarkable salubrity. Another influence also materially tends to give even the most large and comprehensive system of Ethics a certain apparent narrowness and one-sidedness in practice. A world-regenerating system of Ethics, such as Christianity, is not a thing, like a treatise on Logic, written in a book and laid on the shelf, and allowed quietly to work its way with whosoever may choose to take it up. It is an active, aggressive, invasive power; it is a strong medicine to knock down a strong disease; it is a charge of cavalry dashing onwards, like a storm, to break the solid squares of an opposing infantry, bristling with many spears. Such a movement is necessarily one-sided; all movement is one-sided; speculation only is catholic. We must not therefore expect Christianity, of all moral forces the most impetuous and the most imperious, to be free from this fault. It had to swoop down, so to speak, on violent wings from the spiritual side of our nature upon the sensualism of {194} the Greeks, otherwise it could not succeed; and its most distinctive features will
