Experience shows that what great role pratice and experience play in education; pratice, the prolonged exercice lead to habit: exemple suggests imitation. Habit can become a second nature, but, wrongly directed (or guided), it may also heighten (or intensify) unfortunate tendencies and be an obstacle to progress.

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.

If the present civilisation does not acquire some stable moral fondations ("bases morales stables", Fr.), its existence will hardly be more assured than that of the civilisations that have preceeded it, and which have fallen (or collapse, or failed).

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.

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.)

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.)

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.
