There are 4 main approaches in sociology covering politics. First one is functionalist approach, second is pluralist approach, third is elite theory, and fourth is Marxist-conflict theory.
In functionalist approach, society is evaluated in terms of basic needs. The state has emerged as a necessity within the society. These needs are: 1.
+"I should whap your backside for such carelessness,"
+"This in the hand of an enemy can let out your life's blood! You're an apt pupil, none better, but I've warned you that not even in play do you let a man inside your guard with death in his hand."
-"I guess I'm not in the mood for it today," Paul said.
+"Mood?" Halleck's voice betrayed his outrage even through the shield's filtering.
+"What has mood to do with it? You fight when the necessity arises -no matter the mood! Mood's a thing for cattle or making love or playing the baliset. It's not for fighting."
"I'm sorry, Gurney."
"You're not sorry enough!"
“Necessity is something that exists in the mind, not in objects” (T: 165). Accordingly, Hume has been typically read as “the great denier of necessary connections” (Lewis 1986f: ix).
“This is the excellent foppery of the world, that,
when we are sick in fortune,--often the surfeit
of our own behavior,--we make guilty of our
disasters the sun, the moon, and the stars: as
if we were villains by necessity; fools by
heavenly compulsion; knaves, thieves, and
treachers, by spherical predominance; drunkards,
liars, and adulterers, by an enforced obedience of
planetary influence; and all that we are evil in,
by a divine thrusting on: an admirable evasion
of whoremaster man, to lay his goatish
disposition to the charge of a star.”
