“With the theory of happiness, of well-being, as the primary aim of existence we shall only form egoistic men, worshippers of the material, who will cary the old passions into the new order of things and corrupt it in a few months. We have therefore to find a principle of education superior to any such theory, which shall guide men to better things, teach them constancy in self-sacrifice and link them with their fellow men without making them dependent on the ideas of a single man or on the strength of all. And this principle is Duty. We must convince men that they, sons of one only God, must obey one only law, here on earth; that each one of them must live, not for himself, but for others; that he object of their life is not to be more or less happy, but to make themselves and others better: that to fight against injustice and error for the benefit of their brothers is not only right, but a duty; a duty not to be neglected without sin, – the duty of their whole life.” Joseph Mazzini, The Duties of Man
