In the state of nature... all men are born equal, but they cannot continue in this equality. Society makes them lose it, and they recover it only by the protection of the law.
Baron de MontesquieuWhen the legislative and executive powers are united in the same person, or in the same body of magistrates, there can be no liberty; because apprehensions may arise, lest the same monarch or senate should enact tyrannical laws, to execute them in a tyrannical manner.
Baron de Montesquieu
