“An integral part of the collective existence, man feels his dignity at the same time in himself and in others, and thus carries in his heart the principle of a morality superior to himself. This principle does not come to him from outside; it is secreted within him, it is immanent. It constitutes his essence, the essence of society itself. It is the true form of the human spirit, a form which takes shape and grows towards perfection only by the relationship that every day gives birth to social life. Justice, in other words, exists in us like love, like notions of beauty, of utility, of truth, like all our powers and faculties”.
Pierre-Joseph Proudhon, De la justice dans la révolution et dans l’église
