Kant aur Kelsen ke Social Contract ke Baavjood

Main samajh nahin pa raha hoon ki kaise HEGEL aur NIEZSCHE ki vichardharaon se Kant aur Kelsen ka Social Contract samajhna chahiye. Jab maine ek post padha, usne Kelsen ke Pure Theory of Law mein Social Contract ko ek formal, scientific concept ke roop mein describe kiya tha. Lekin jab maine HEGEL aur NIEZSCHE ki vichardhara padhi, to Social Contract ko ek historico-philosophical concept ke roop mein dekhne ka moka mila. Kya yeh dwaarik samajh hai ki HEGEL aur NIEZSCHE ki vichardharaon mein Social Contract ka darshana kuch aur hai?
