"My freedom, in order to fulfill itself, requires that it emerge into an open future: it is other men who open the future to me, it is they who, setting up the world of tomorrow, define my future; but if, instead of allowing me to participate in this constructive movement, they oblige me to consume my transcendence in vain, if they keep me below the level which they have conquered and on the basis of which new conquests will be achieved then they are cutting me off from the future, they are changing me into a thing."
