pon the Civil Part of our Constitution, having often
entertained my self with Reflections on this Subject, which I have not
met with in other Writers.

That Form of Government appears to me the most reasonable, which is most
conformable to the Equality that we find in human Nature, provided it be
consistent with publick Peace and Tranquillity. This is what may
properly be called Liberty, which exempts one Man from Subjection to
another so far as the Order and Oeconomy of Government will permit.

Liberty should reach every Individual of a People, as they all share one
common Nature; if it only spreads among particular Branches, there had
better be none at all, since such a Liberty only aggravates the
Misfortune of those who are depriv'd of it, by setting before them a
disagreeable Subject of Comparison. This Liberty is best preserved,
where the Legislative Power is lodged in several Persons, especially if
those Persons are of different Ranks and Interests; for where they are
of the same Rank, and consequently have an Interest to manage peculiar
to that Rank, it differs but little from a Despotical Government in a
single Person. But the greatest Security a People can have for their
Liberty, is when the Legislative Power is in the Hands of Persons so
happily distinguished, that by providing for the particular Interests of
their several Ranks, they are providing for the whole Body of the
People; or in other Words, when there is no Part of the People that has
not a common Interest with at least one Part of the Legislators.

If there be but one Body of Legislators, it is no better than a Tyranny;
if there are only two, there will want a casting Voice, and one of them
must at length be swallowed up by Disputes and Contentions that will
necessarily arise between them. Four would have the same Inconvenience
as two, and a greater Number would cause too much Confusion. I could
never read a Passage in Polybius, and another in Cicero, to this
Purpose, without a secret Pleasure in applying it to the English
Constitution, which it suits much better than the Roman. Both these
great Authors give the Pre-eminence to a mixt Government, consisting of
three Branches, the Regal, the Noble, and the Popular. They had
doubtless in their Thoughts the Constitution of the Roman Commonwealth,
in which the Consul represented the King, the Senate the Nobles, and the
Tribunes the People. This Division of the three Powers in the Roman
Constitution wa
