The more a man is successful in getting out (or coming out) from his own individuality, of his egoist self, and to control (or dominate) the instincts of his physical nature, the more his character, by rising above material contingencies, widen, become free and independent.
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.
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.
Whether we had a (good) moral intuition more developed, we would be as much morally disgusted by the rapacity of those who try to benefit from, and monopolize (or secure or corner), having no consideration (regardless or irrespective of) for others ("autrui", Fr.), than we physically are by a sickening (or nauseating) smell.
Moral improvement (or perfecting) require an evolution leading to a higher consciousness, which is the true torch of life; it is what we have failed too much to appreciate, and that which would be fatal to fail to appreciate any longer ("pluslongtemps", Fr.); For if we do not take it upon ourselves to remedy in time to the moral colapse (or bankruptcy) that already threaten, the whole civilisation will risks to disappear.
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.
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.
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.
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.
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.
