The world becomes today a more and more competitive place. Welfare, even the natural, equilibrated one, is costly. And this requires work, efficient work. However, we live in a world which has earned reaction speed and finds rapidly solutions. The motivation becomes in this way the main lever for the re-equilibration of the human being in the present day society. This paper deals with the ticklish problems of work motivation from the perspective of the invalidation of the trenchant superiority of the stimuli of material kind which can insure the safety of the individual. The force of the word, by means of the countless implications at the level of the human psychology, has the power to transform the individual, to re-spiritualize him in an opaque world, glued to material goods and in which there is almost no message.
