When under the influence of certain (or some) reasons (or causes) (alcohol, war, etc - added Spir here) the low instincts are unbridled (or unrestrained), the brute appears (or come forward, "apparait", Fr.) and rule over (or dominate), stifling every ("toute", Fr.) noble, generous impulse; it is then the ruin (or downfall or decline) of any humanity in man.
Man is in pursuit of two goals: he is looking for happinesse and, being by essence empty ("étant vide par essence", Fr.), he is trying to fill (or take up, - "remplir", Fr.) his life; the latter reason play a more considerable role than we ordinarily think. What we take for vainglory, ambition, love of power and riches (or wealth), is often, indeed, a need to mask this emptiness, a need to let one's hair down (or to live it up), to put oneself on a false scent or trail. (de se donner le change", Fr.)
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.
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.
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.)
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.
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.
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.
Men who have sacrifice their well-being, and even their lives, for the cause of truth or the public good, are, from an empirical point of view - which scorn ("fait fi", Fr.) virtue and altruism - regarded as insane or fools; but, from a moral standpoint, they are heros who do honour ("qui honorent", Fr.) humanity.
The more gifted by nature is a man, the more is deplorable the abuse that he does by using them to shameful ends. A swindler (or crook) of higher condition is more blameworthy than a vulgar scoundrel; an intelligent eveil-doer, having benefited from a higher education, represent a more saddening phenomenon ("phénomène", Fr.) than an unfortune illiterate fellow having commited an offence.
Besides the progress of industry and technique, we see a growing discontent among the masses; we see, besides the expansion ("expansion,", Fr.) of instruction, distrust and hatred expanding among nations ("s'étendre la méfiance et la haine entre," Fr.), that vie with one another ("qui rivalisent à l'envi," Fr.), by the increase of their armies and the improvement of their engines of murder ("engins meurtriers", Fr).
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.
