“The more we understand what is happening in the world, the more frustrated we often become, for our knowledge leads to feelings of powerlessness.
We feel that we are living in a world in which the citizen has become a mere spectator or a forced actor, and that our personal experience is politically useless and our political will a minor illusion. Very often, the fear of total permanent war paralyzes the kind of morally oriented politics, which might engage our interests and our passions. We sense the cultural mediocrity around us-and in us-and we know that ours is a time when, within and between all the nations of the world, the levels of public sensibilities have sunk below sight; atrocity on a mass scale has become impersonal and official; moral indignation as a public fact has become extinct or made trivial.
We feel that distrust has become nearly universal among men of affairs, and that the spread of public anxiety is poisoning human relations and drying up the roots of private freedom. We see that people at the top often identify rational dissent with political mutiny, loyalty with blind conformity, and freedom of judgment with treason. We feel that irresponsibility has become organized in high places and that clearly those in charge of the historic decisions of our time are not up to them. But what is more damaging to us is that we feel that those on the bottom-the forced actors who take the consequences-are also without leaders, without ideas of opposition, and that they make no real demands upon those with power.”

Variant translation: The more we learn about the world, and the deeper our learning, the more conscious, clear, and well-defined will be our knowledge of what we do not know, our knowledge of our ignorance. The main source of our ignorance lies in the fact that our knowledge can only be finite, while our ignorance must necessarily be infinite.

Context: The more we learn about the world, and the deeper our learning, the more conscious, specific, and articulate will be our knowledge of what we do not know, our knowledge of our ignorance. For this, indeed, is the main source of our ignorance — the fact that our knowledge can be only finite, while our ignorance must necessarily be infinite.

Introduction
The Nature of the Physical World (1928)
Context: In physics we have outgrown archer and apple-pie definitions of the fundamental symbols. To a request to explain what an electron really is supposed to be we can only answer, "It is part of the A B C of physics".
The external world of physics has thus become a world of shadows. In removing our illusions we have removed the substance, for indeed we have seen that substance is one of the greatest of our illusions. Later perhaps we may inquire whether in our zeal to cut out all that is unreal we may not have used the knife too ruthlessly. Perhaps, indeed, reality is a child which cannot survive without its nurse illusion. But if so, that is of little concern to the scientist, who has good and sufficient reasons for pursuing his investigations in the world of shadows and is content to leave to the philosopher the determination of its exact status in regard to reality. In the world of physics we watch a shadowgraph performance of the drama of familiar life. The shadow of my elbow rests on the shadow table as the shadow ink flows over the shadow paper. It is all symbolic, and as a symbol the physicist leaves it. Then comes the alchemist Mind who transmutes the symbols. The sparsely spread nuclei of electric force become a tangible solid; their restless agitation becomes the warmth of summer; the octave of aethereal vibrations becomes a gorgeous rainbow. Nor does the alchemy stop here. In the transmuted world new significances arise which are scarcely to be traced in the world of symbols; so that it becomes a world of beauty and purpose — and, alas, suffering and evil.
The frank realisation that physical science is concerned with a world of shadows is one of the most significant of recent advances.
