When a machine is produced it is accompanied by a set of instructions for its use. An engineer is also commis¬sioned to give a practical demonstration of how the machine functions. Man is an even more intricately de¬signed but animate machine. When he is born, he suddenly finds himself in a world where no mountain bears an inscription answering questions concerning the nature of the world, or explaining how he should live on earth. No educational institution produces experts who know the secret of life or who can provide man with practical guidance.
