Context: Be reverent before the dawning day. Do not think of what will be in a year, or in ten years. Think of to-day. Leave your theories. All theories, you see, even those of virtue, are bad, foolish, mischievous. Do not abuse life. Live in to-day. Be reverent towards each day.
Context: Be reverent before the dawning day. Do not think of what will be in a year, or in ten years. Think of to-day. Leave your theories. All theories, you see, even those of virtue, are bad, foolish, mischievous. Do not abuse life. Live in to-day. Be reverent towards each day. Love it, respect it, do not sully it, do not hinder it from coming to flower. Love it even when it is gray and sad like to-day. Do not be anxious. See. It is winter now. Everything is asleep. The good earth will awake again. You have only to be good and patient like the earth. Be reverent. Wait. If you are good, all will go well. If you are not, if you are weak, if you do not succeed, well, you must be happy in that. No doubt it is the best you can do. So, then, why will? Why be angry because of what you cannot do? We all have to do what we can.... Als ich kann.

The Value of Science (1955)
Context: We are at the very beginning of time for the human race. It is not unreasonable that we grapple with problems. But there are tens of thousands of years in the future. Our responsibility is to do what we can, learn what we can, improve the solutions, and pass them on.
... It is our responsibility to leave the people of the future a free hand. In the impetuous youth of humanity, we can make grave errors that can stunt our growth for a long time. This we will do if we say we have the answers now, so young and ignorant as we are. If we suppress all discussion, all criticism, proclaiming "This is the answer, my friends; man is saved!" we will doom humanity for a long time to the chains of authority, confined to the limits of our present imagination. It has been done so many times before.
... It is our responsibility as scientists, knowing the great progress which comes from a satisfactory philosophy of ignorance, the great progress which is the fruit of freedom of thought, to proclaim the value of this freedom; to teach how doubt is not to be feared but welcomed and discussed; and to demand this freedom as our duty to all coming generations.
