Montesquieu

“ It is true that men do not always perceive these relations: often indeed, when they do perceive them, they turn aside from them, their own interest being always that which they perceive most clearly. Justice cries aloud; but her voice is hardly heard in the tumult of the passions.
Men act unjustly, because it is their interest to do so, and because they prefer their own satisfaction to that of others. They act always to secure some advantage to themselves: no one is a villain gratis; there is always a determining motive, and that motive is always an interested one. ”

“ IF there is a God, my dear Rhedi, HE must of necessity be just; because, if He were not so, He would be the worst and most imperfect of all beings.
Justice is a true relation existing between two things; a relation which is always the same, whoever contemplates it, whether it be God, or an angel, or lastly, man himself. ”

“ We are surrounded by men stronger than ourselves; they can injure us in a thousand different ways, and with impunity three times out of four: what a satisfaction it is for us to know that there is in the heart of all men, an innate principle which fights in our favour, and shields us from their attempts! ”
