This unity may be destroyed in two ways: either by vesting the power in two or more magistrates of equal dignity and authority; or by vesting it ostensibly in one man, subject, in whole or in part, to the control and co-operation of others, in the capacity of counsellors to him. Of the first, the two Consuls of Rome may serve as an example; of the last, we shall find examples in the constitutions of several of the States. New York and New Jersey, if I recollect right, are the only States which have intrusted the executive authority wholly to single men.(1) Both these methods of destroying the unity of the Executive have their partisans; but the votaries of an executive council are the most numerous. They are both liable, if not to equal, to similar objections, and may in most lights be examined in conjunction.
The experience of other nations will afford little instruction on this head. As far, however, as it teaches any thing, it teaches us not to be enamoured of plurality in the Executive. We have seen that the Achaeans, on an experiment of two Praetors, were induced to abolish one. The Roman history records many instances of mischiefs to the republic from the dissensions between the Consuls, and between the military Tribunes, who were at times substituted for the Consuls. But it gives us no specimens of any peculiar advantages derived to the state from the circumstance of the plurality of those magistrates. That the dissensions between them were not more frequent or more fatal, is a matter of astonishment, until we advert to the singular position in which the republic was almost continually placed, and to the prudent policy pointed out by the circumstances of the state, and pursued by the Consuls, of making a division of the government between them. The patricians engaged in a perpetual struggle with the plebeians for the preservation of their ancient authorities and dignities; the Consuls, who were generally chosen out of the former body, were commonly united by the personal interest they had in the defense of the privileges of their order. In addition to this motive of union, after the arms of the republic had considerably expanded the bounds of its empire, it became an
