Sujet : La pensée fait-elle obstacle a la vie ?

Extrait du corrigé : En effet, nous ne sommes pas les vivants les plus forts physiquement, mais par la pensée, nous possédons un pouvoir inaccessible à tout autre vivant. « L'homme n'est qu'un roseau, mais un roseau pensant. Il ne faut pas que l'univers entier s'arme pour l'écraser : une vapeur, une goutte d'eau suffit pour le tuer. Mais quand l'univers l'écraserait, l'homme serait encore plus noble que ce qui le tue, parce qu'il sait qu'il meurt ; et l'avantage que l'univers a sur lui, l'univers n'en sait rien ». Il apparaît ainsi que notre pensée est un avantage inestimable, qui nous confère une noblesse que tout autre vivant ignore, en particulier par le fait que nous savons que nous mourrons. C'est d'ailleurs cette pensée qui donne toute son importance à la vie. En la sachant éphémère, nous pouvons d'autant plus apprécier les instants qu'elle nous donne, d'une part, et utiliser cette pensée pour vivre au mieux d'autre part : « Travaillons donc à bien penser : voilà le principe de la morale. » L'apogée de notre pensée consisterait alors à vivre en suivant entièrement ce que la pensée nous apprend.                  II/  LA PENSEE NOUS EMPECHE DE VIVRE.
