Why do we need systems?

Religion and nationalism, as well as any custom and any belief however absurd and degrading, if it only connects the individual with others, are refuges from what man most dreads: isolation.

… not be able to relate himself to any system which would give meaning and direction to his life, he would be filled with doubt, and this doubt eventually would paralyze his ability to act - that is, to live.

--Erich Fromm
