"Truthfulness has never been counted among the political virtues, and lies have always been regarded as justifiable tools in political dealings. Whoever reflects on these matters can only be surprised by how little attention has been paid, in our tradition of philosophical and political thought, to their significance, on the one hand for the nature of action and, on the other, for the nature of our ability to deny in thought and word whatever happens to be the case. This active, aggressive capability is clearly different from our passive susceptibility to falling prey to error, illusion, the distortions of memory, and to whatever else can be blamed on the failings of our sensual and mental apparatus''.

"Men who act, to the extent that they feel themselves to be the masters of their own futures, will forever be tempted to make themselves masters of the past, too. Insofar as they have the appetite for action and are also in love with theories, they will hardly have the natural scientist’s patience to wait until theories and hypothetical explanations are verified or denied by facts. Instead, they will be tempted to fit their reality — which, after all, was man-made to begin with and thus could have been otherwise — into their theory, thereby mentally getting rid of its disconcerting contingency''.

"The kind of thinking that presents both A and C as undesirable, therefore settles on B, hardly serves any other purpose than to divert the mind and blunt the judgment for the multitude of real possibilities''.

"Not only are the people and their elected representatives denied access to what they must know to form an opinion and make decisions, but also the actors themselves, who receive top clearance to learn all the relevant facts, remain blissfully unaware of them. And this is so not because some invisible hand deliberately leads them astray, but because they work under circumstances, and with habits of mind, that allow them neither time nor inclination to go hunting for pertinent facts in mountains of documents, 99½ per cent of which should not be classified and most of which are irrelevant for all practical purposes''.

"A characteristic of human action is that it always begins something new, and this does not mean that it is ever permitted to start ab ovo, to create ex nihilo. In order to make room for one’s own action, something that was there before must be removed or destroyed, and things as they were before are changed. Such change would be impossible if we could not mentally remove ourselves from where we physically are located and imagine that things might as well be different from what they actually are...It is by no means a matter of course that we can say, “The sun shines,” when it actually is raining (the consequence of certain brain injuries is the loss of this capacity); rather, it indicates that while we are well equipped for the world, sensually as well as mentally, we are not fitted or embedded into it as one of its inalienable parts. We are free to change the world and to start something new in it. Without the mental freedom to deny or affirm existence, to say “yes” or “no” — not just to statements or propositions in order to express agreement or disagreement, but to things as they are given, beyond agreement or disagreement, to our organs of perception and cognition — no action would be possible; and action is of course the very stuff politics are made of''.
