Simple government is better in itself, just because it is simple. But when the executive power is not sufficiently dependent upon the legislative power, i.e. when the prince is more closely related to the Sovereign than the people to the prince, this lack of proportion must be cured by the division of the government; for all the parts have then no less authority over the subjects, while their division makes them all together less strong against the Sovereign.
The same disadvantage is also prevented by the appointment of intermediate magistrates, who leave the government entire, and have the effect only of balancing the two powers and maintaining their respective rights. Government is then not mixed, but moderated.
