Above all, my personal question, “What am I with my desires?” remained quite unanswered. And I understood that those sciences are very interesting and attractive, but that they are exact and clear in inverse proportion to their applicability to the question of life: the less their applicability to the question of life, the more exact and clear they are, while the more they try to reply to the question of life, the more obscure and unattractive they become. If one turns to the division of sciences which attempt to reply to the questions of life⁠—to physiology, psychology, biology, sociology⁠—one encounters an appalling poverty of thought, the greatest obscurity, a quite unjustifiable pretension to solve irrelevant questions, and a continual contradiction of each authority by others and even by himself. If one turns to the branches of science which are not concerned with the solution of the questions of life, but which reply to their own special scientific questions, one is enraptured by the power of man’s mind, but one knows in advance that they give no reply to life’s questions. Those sciences simply ignore life’s questions.

They say: “To the question of what you are and why you live we have no reply, and are not occupied with that; but if you want to know the laws of light, of chemical combinations, the laws of development of organisms, if you want to know the laws of bodies and their form, and the relation of numbers and quantities, if you want to know the laws of your mind, to all that we have clear, exact and unquestionable replies.”

In general the relation of the experimental sciences to life’s question may be expressed thus: Question: “Why do I live?” Answer: “In infinite space, in infinite time, infinitely small particles change their forms in infinite complexity, and when you have understood the laws of those mutations of form you will understand why you live on the earth.”
