Factual truth is always related to other people: it concerns events and circumstances in which many are involved; it is established by witnesses and depends upon testimony; it exists only to the extent that it is spoken about, even if it occurs in the domain of privacy. It is political by nature.

The ideal subject of totalitarian rule is not the convinced Nazi or the dedicated communist, but people for whom the distinction between fact and fiction, true and false, no longer exists.

There will always be One against All, one person against all others. [This is so] not because One is terribly wise and All are terribly foolish, but because the process of thinking and researching, which finally yields truth, can only be accomplished by an individual person. In its singularity or duality, one human being seeks and finds – not the truth (Lessing) –, but some truth.

Power corresponds to the human ability not just to act but to act in concert. Power is never the property of an individual; it belongs to a group and remains in existence only so long as the group keeps together. When we say of somebody that he is 'in power' we actually refer to his being empowered by a certain number of people to act in their name. The moment the group, from which the power originated to begin with ... disappears, 'his power' also vanishes.

Nothing we use or hear or touch can be expressed in words that equal what is given by the senses.

Political institutions, no matter how well or badly designed, depend for continued existence upon acting men; their conservation is achieved by the same means that brought them into being. Independent existence marks the work of art as a product of making; utter dependence upon further acts to keep it in existence marks the state as a product of action.

There are no dangerous thoughts; thinking itself is dangerous.
