I propose a contribution of Philosophy of education. I would like to demonstrate with arguments and also reading data of statistics fields and/or qualitative pedagogical research, that we are destined to be alone as adults. This is a truth that endures since the times of J.J. Rousseau; but, like sings G. Gaber not long time ago, this solitude is not simply narcissism, enjoyment or platonic beauty. I agree, with J. Lacan, that this loneliness is the keystone to build a new form of social-link in our age; a link or a democracy very different from that dreamed by the Roussonians. Women and men that accept to be alone, they are able to create a social-link without identify yourself to a leader (as S. Freud has well described) or constituting themselves in elites in elite to the right as on the left.
