As the antagonism between those who possess, and those who do not, is becoming more acute day after day, we can already foresee a moment when it will bring about ("entraînera", Fr.) severe (big, high, intense, - "grands", Fr.) disasters, if we do turn (direct, aim, - "dirige", Fr.) life in time the social life in new directions (or ways, - "dans des voies nouvelles", Fr.)
Outward, thanks to the knowledge of physical laws, man could subdue (or subjugate...) nature, but inwardly, he remained a slave to it. For, when all is said and done, at what is aiming all this display (or deployment) of activity, if not to realized outward profits, to provide material pleasure (or enjoyment). It is not the first time that men sell their birth right for a dish of lentils, and thus disown (or repudiate or deny) the best of thmeselves.
The basic notion of justice, is that the rights of everybody are equals, in principle. In the rights of others, we have to respect our own rights. It is only in that condition that we can reasonnably require that it be respected by others.
In ancient times, any man rising up above the common people tried to shape his life according to his principles; it is no longer like than now; it is (because) for the ancients, moral was a principle of inner life, whereas in our days, most of the time one is content to adhere to an official moral, that we recognize in theory, but that one does not care to put into practice.
Men spend their life down here in the worship of petty (or mean) interests and the search of perishable things, and with that ("et avec cela", Fr.) they pretend to perpetuate for all eternity their self ("moi", Fr.) so hardly worthy ("digne", Fr.) of it.
Deep down, everything boils down ("au fond tout se ramène", Fr.) to the following simple question; Do we really want justice and the realization in this world of higher principles, or else do we want to serve selfish, short-sighted (à courte vue", Fr.) interests, which, when all is said and done, are also prejudicial (or detrimental, or harmful) to those very same that pursue them?
If pity was always equally alive and acting in all individuals and in all circumstances, we could do away with moral. Unfortunately, it is not compassion, but rather it's contrary, selfishness, that act most strongly in us.
A man, engaged in his simple reflections in everyday life, will comprehend neither the possibility, nor the benefits of self-sacrifice, but, when given ("qu'on lui donne", Fr.) a great cause to defend, and he will find only natural to sacrifice oneself for it.
If man do not find in himself the required (or wished, or wanted, - "voulue", Fr.) force to accomplish his moral aspirations, he can try to purt himself in the conditions suitable to assist (or promote, or further, -"favoriser", Fr.) his self-control.
The fact that men have a same origin and live in the same universe means that they are representatives of a same unity. Deep down, they are also related (or connected) among them; that they consider (or not) themselves as strangers, this just depends on the feeling (or sensation) that dictate their relationships. In their country, two fellow coutrymen whose paths berely cross (or see each only only briefly) with inferrence, would effusively rush themselves up (or throw themselves) into each other arms if they would happen to meet in a desert, among Cannibles.
