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.
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.
Infringing upon (or encroaching) the right of a single person, we overthrow (or turn upside down) the whole order on which rest legal agreements; for if we break (or transgress or violate) the undertakings enter unto ("les engagements contractés", Fr.), nothing assure that we will not break them, possibly ("éventuellement", Fr.) in another.
As long as men will not be freed from their errors and delusions, humanity will not be able to go towards ("marcher vers", Fr.) the accomplishment of its true destinies.
The distinction between right and wrong ("la distinction du bien et du mal", Fr.), is nothing else than their unyielding (or implacable) opposition; thus the moral consciousness is an innate and intimate revelation of the absolute, which goes beyond (or goes pass, or exceed) every empirical data (or given information). It is only on these principles that we will be able to establish ("pourront être édifiées", Fr.) the real basis of morality.
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.
There are (or is) indeed no contradiction between science and religion, the fields of which are different, and which, far from mutually fighting and persecute, must, on the contrary, complete each other.
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.
The appalling and shameful scene ("spectacle", Fr.) of disarray and illogicality that manifest itself in the thought and deeds of men, will no longer be seen, once these will possess an enlighten consciouness.
Apart from selfish reasons, such as fear of punishments, fear of blame, of dishonour, etc, there remains only two motives that can stop (or prevent, "empâecher", Fr.) men from acting badly; the natural sense of commiseration (or "sympathy", - "commisération", Fr.) for one's fellow men - compassion, and the influence of education, by association of ideas ("par l'association d'idées", Fr.) - habit.
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.
Religion is not simply a theory, it is a higher life, of which morality is an integral part - a life devoted to the worship of the good and the true, for God, the absolute, is the supreme source of all perfection" ("La religion n'et pas une smple théorie, elle est une vie supérieure, dont la moralité fait partie intégrante - une vie vouée au culte du bien et du vrai, car Dieu, l'absolu est la source de toute perfection", Fr.)
To reform society, and with it humanity, there is only one mean; to transform the mentality of men, to direct them ("les orienter", Fr.) in a new spirit.
