@Pukka Sahib,
Look here you Rabbit... All our social forms are attempts to realize our moral forms... The goods of the preamble were supposed to be achieved by the constitution... Aristotle says as much, that it is for good that governments are created, and he says that because good is the aim of all human activity... The problem is not the ideal, or the object, but is the fact that people lose sight of the objects and ideals their social forms are supposed to achieve, and start thinking of government, for example, as a thing in itself, the possession of which can lead to wealth out of power... As far as the actual legislating of morality the problem is where to begin... Since moral forms all lack exact definition no one can fix them by law... In order to coerce certain moral behavior you must do something immoral, coerce, which means to take the freedom necessary to be moral..
There is an expression in Latin: Montani Semper Liberi; Montaineers are always free... No one can ever be compelled to be free, but people can be compelled to be slaves... People can be tied to a plow, but no one is ever driven to the mountain top... In fact, freedom is as essential to morality as morality is to freedom... One never needs more government than to protect oneself from others, and the moment anyone thinks to turn government to the control of others they are the ones all need protection from...So, you cannot legislate morality, but you can by government encourage the situation in which all can be freely moral, and morally free...
It was a point in common with all the major Western Religions that the intelligent must control the brutes... What was there then to keep the intelligent from growing brutish??? The Communists were usually the most moral of men, but given the power of the state they soon became so many Stalins...
Power over others is that quality a moral man most avoids, and power over self is that quality he most desires... The one is freedom, and the other is slavery for both slave and master...
