H.L.A.Hart’s semi­nal book The Con­cept of Law ent­ails argu­ments which are also of sub­stan­ti­al importance for social theo­ry: his cla­im that the exis­tence of social and legal norms pre­sup­po­ses the dis­se­mi­na­ti­on of an inter­nal point of view among the mem­bers of a social and legal com­mu­ni­ty pres­ents a serious chall­enge for any expl­ana­ti­on of social order. Hart­mut Kli­emt empha­si­zes this aspect of Hart’s work time and again in his own wri­tin­gs and sure­ly with very good reasons. In my paper I will try to recon­s­truct Hart’s theo­ry in detail. I will argue that we have to cla­ri­fy the dif­fe­rent dimen­si­ons of the con­cept of an inter­nal point of view to be able to assess its con­se­quen­ces for a theo­ry of social and legal order espe­ci­al­ly for a ratio­nal choice approach which at first sight seems to be incom­pa­ti­ble with the con­cept of an inter­nal point of view.
