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.
In life we only try to produce, to win, and enjoy the more we can; in science, to discoverand invent the more we can; in religion, to dominate (or rule over) on the greatest number of people we can; whereas the forming of the character, the further development (or in-dept analysis, "appronfondissement", Fr.) of the faculties of the intelligence ("les facultés de l'intelligence", Fr.), the refinement of the consciousness and of the heart, are considered incidental (or subordinate) things.
The need for sociability induce man to be in touch with his fellow men. However, this need might not ("ne saurait", Fr.) find its full (or complete) satisfaction in the conventional (or superficial, - "conventionnel", Fr.) and deceitful world, in which (or where) everyone is mainly (or mostly) trying to assert oneself in front of others ("devant les autres", Fr.), to appear, and hoping to find in society ("mondaine", Fr.) relationships some advantages for his interest and vanity (or vainglory or conceit", 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.
It must be all the same to the citizens ("ressortissants", Fr.) of a country that their governing (those in power) speak such language or such other ("telle langue ou telle autre", Fr.); likewise that it must be all the same to them that these adhere to such or such religion, so long as a full (or complete) liberty is equally garantee for everyone.
The intellectual development of man, far from having get men away from war, has, rather, on the contrary, bring them to a refinment always more perfected in the art of killing. They even came to raise the methods of slaughter to the rank of "science"... We would not (On ne saurait", Fr.) imagine a more extraordinary moral blindness!
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 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.
Nothing that rest on some contradictory basis shall succeed or last in the long run ("ne saurait réussir ou durer, à la longue", Fr.); all that involve (or imply...) a contradiction is fatally destined, early or late, to disintegrate and disappear.
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.
Up to here, in general, we have mainly stuffed the brain of the young people with a indigestible multitude of varios notions, without thinking about enough of the prime necessity to form their character.
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.
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.
