In our vital need ... science has nothing to say to us. It excludes in principle precisely the question which man, given over in our unhappy times to the most portentous upheavals, finds the most burning: questions about the meaning or meaninglessness of this whole human existence. Do not these questions, universal and necessary for all men, demand universal reflections and answers based on rational insight? In the final analysis they concern man as a free, self-determining being in his behaviour toward the human and extrahuman surrounding world and free in regard to his capacities for rationally shaping himself himself and his surrounding world.
