The moral improvement demands an evolution leading to a higher consciousness.

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.

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.

See that unfortunate soldier who is falling hurt to death ("tombe blessé à...", Fr.) on the battlefield; he learns that his folks have vanquished and dies happy. He detached himself from himself (s'est détacher de lui-même", Fr.), has identified himself with something greater and more lasting than himself; his homeland ("patrie", Fr.); thus, while dying as an individual, he has the certainty to survive in a larger existence.

Only a moral education based on free inner discipline can bring to bear a salutary action and lead to a true morality.

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.

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.
