Pagans may have, heretics cannot have, the same principles as Catholics; if the latter have the same, they are not real heretics, but in ignorance. Principle is a better test of heresy than doctrine. Heretics are true to their principles, but change to and fro, backwards and forwards, in opinion; for very opposite doctrines may be exemplifications of the same principle. Thus the Antiochenes and other heretics sometimes were Arians, sometimes Sabellians, sometimes Nestorians, sometimes Monophysites, as if at random, from fidelity to their common principle, that there is no mystery in theology. Thus Calvinists become Unitarians from the principle of private judgment. The doctrines of heresy are accidents and soon run to an end; its principles are everlasting.
This, too, is often the solution of the paradox "Extremes meet," and of the startling reactions which take place in individuals; viz., the presence of some one principle or condition, which is dominant in their minds from first to last. If one of two contradictory alternatives be necessarily true on a certain hypothesis, then the denial of the one leads, by mere logical consistency and without direct reasons, to a reception of the other. Thus the question between the Church of Rome and Protestantism falls in some minds into the proposition, "Rome is either the pillar and ground of the Truth, or she is Antichrist;" in proportion, then, as they revolt from considering her the latter are they compelled to receive her as the former. Hence, too, men may pass from infidelity to Rome, and from Rome to infidelity, from a conviction in both courses that there is no tangible intellectual position between the two.
Protestantism, viewed in its more Catholic aspect, is doctrine without active principle; viewed in its heretical, it is active principle without doctrine. Many of its speakers, for instance, use eloquent and glowing language about the Church and its characteristics: some of them do not realize what they say, but use high words and general statements about "the faith," and "primitive truth," and "schism," and "heresy," to which they attach no definite meaning; while others speak of "unity," "universality," and "Catholicity," and use the words in their own sense and for their own ideas.

The science of grammar affords another instance of the existence of special laws in the formation of systems. Some languages have more elasticity than others, and greater capabilities; and the difficulty of explaining the fact cannot lead us to doubt it. There are languages, for instance, which have a capacity for compound words, which, we cannot tell why, is in matter of fact denied to others. We feel the presence of a certain character or genius in each, which determines its path and its range; and to discover and enter into it is one part of refined scholarship. And when particular writers, in consequence perhaps of some theory, tax a language beyond its powers, the failure is conspicuous. Very subtle, too, and difficult to draw out, are the principles on which depends the formation of proper names in a particular people. In works of fiction, names or titles, significant or ludicrous, must be invented for the characters introduced; and some authors excel in their fabrication, while others are equally unfortunate. Foreign novels, perhaps, attempt to frame English surnames, and signally fail; yet what every one feels to be the case, no one can analyze: that is, our surnames are constructed on a law which is only exhibited in particular instances, and which rules their formation on certain, though subtle, determinations.
And so in philosophy, the systems of physics or morals, which go by celebrated names, proceed upon the assumption of certain conditions which are necessary for every stage of their development. The Newtonian theory of gravitation is based on certain axioms; for instance, that the fewest causes assignable for phenomena are the true ones: and the application of science to practical purposes depends upon the hypothesis that what happens to-day will happen to-morrow.
And so in military matters, the discovery of gunpowder developed the science of attack and defence in a new instrumentality. Again, it is said that when Napoleon began his career of victories, the enemy's generals pronounced that his battles were fought against rule, and that he ought not to be victorious.

So states have their respective policies, on which they move forward, and which are the conditions of their well-being. Thus it is sometimes said that the true policy of the American Union, or the law of its prosperity, is not the enlargement of its territory, but the cultivation of its internal resources. Thus Russia is said to be weak in attack, strong in defence, and to grow, not by the sword, but by diplomacy. Thus Islamism is said to be the form or life of the Ottoman, and Protestantism of the British Empire, and the admission of European ideas into the one, or of Catholic ideas into the other, to be the destruction of the respective conditions of their power. Thus Augustus and Tiberius governed by dissimulation; thus Pericles in his "Funeral Oration" draws out the principles of the Athenian commonwealth, viz., that it is carried on, not by formal and severe enactments, but by the ethical character and spontaneous energy of the people.
The political principles of Christianity, if it be right to use such words of a divine polity, are laid down for us in the Sermon on the Mount. Contrariwise to other empires, Christians conquer by yielding; they gain influence by shrinking from it; they possess the earth by renouncing it. Gibbon speaks of "the vices of the clergy" as being "to a philosophic eye far less dangerous than their virtues."[184:1]
