The Tools of Disinformation and Propaganda "In wartime they attack a part of the body that other weapons cannot reach in an attempt to affect the way which participants perform on the field of battle." (Taylor, Munitions of the Mind, p. 9) Therefore the demonstrated tools refer to political propaganda in the two World Wars. Propaganda has the ability to change a war, a natural evil, into a so-called "just" war. Violence then is supposedly defense, no more aggression.

New Forms of Propaganda (in the 19th Century) As soon as governments found out that newspapers were a fantastic and very often unsuspicious medium for supporting propaganda they tried to pull them to their side. Two ways existed: a) to have one's own newspaper, which implies that mostly friends of the government read it. Nothing is regarded as something neutral. b) to keep a good relationship to the most powerful/most frequently read newspapers and then try to make one's opinion theirs. Today mostly elected is b), trying to set up alliances. CNN and the USA during the Gulf War demonstrated an example of that.

The ancient Greek Disinformation was seen as an appropriate tool of politics and rhetoric in ancient Greece. Most of all persuasion was used, which then was considered a type of art. Religion was (and in many ways still is) the best disinformer or manipulator; prophecies were constructed to manipulate the population. The important thing was to use emotions and more than anything else fear as a tool for manipulation. If the oracle of Delphi said a war was to fight and would be won, then the Greek population - because of religious motives - was prepared to fight that war. Propaganda was not only used in wars but also in daily life to bring people together and create a nation. But poets, playwrights and other artists were manipulating as well. Their pieces of literature and plays were full of political messages with different ideologies behind. In the way how theatre at that time was part of life, it can be understood easily that those messages had not only entertainment's character but also a lot of political and social influence. A different and very famous part of disinformation in ancient Greek history was the story of Themistocles, who won the battle of Salamis against the Persians.

Propaganda "For propaganda is a communicative process of persuasion, and persuasion remains an integral part of human discourse in peace as well as in war. (...) propaganda is a process unique to human communication regardless of time, space and geographic location." (Taylor, Munitions of the Mind, preface p. X) The word propaganda is coming from the Catholic Church. In the 17th century the word was used in the fights against the Protestant Reformation (see Taylor, Munitions of the mind, p. 3). Propaganda is using words - of course. But it furthermore uses a huge variety of tools for putting through its purpose. Some of them are: hymns, marches, parades, flags, colors, uniforms, all the typical insignias of the military are pieces of propaganda. And it is no coincidence that the standardization of the uniforms for the army were an invention of Louis XIV, for whom everything seemed to be theatre, a play, a game and all of that was taken into the huge propaganda-system that had to keep his prestige up high. Propaganda makes us think and act in a way we probably would not have chosen to without its influence. Still, in most cases the degree of influence is impossible to know. Studies proving the efficiency of propaganda are doing nothing else but guessing in big parts. But it is efficient, that we know for sure. This is true for commercial advertisements as well as for political propaganda. Short messages are the most effective form of propaganda, look at posters for elections or at advertisements for any product. The best or most effective propaganda is that which is wanted by the people. If propaganda meets the needs of the people then it has good chances to be extremely effective. And of course those needs can be "educated", as Jacques Ellul mentioned already in 1957, in his book Propaganda: The Formation of Men's Attitudes. Political will suffers from the urgency of spreading propaganda. The will to change something - even if it was for the better - is hopelessly lost, if their is no prestige or aura around an idea. A certain amount of disinformation and propaganda is the perfect tool to get ideas through. So, actually, what is the difference between disinformation and propaganda? One difference is that the first one is directed at reason whereas propaganda also touches emotions, most of the time even prefers to influence emotions.

Sputnik At the beginning of the story of today's global data networks is the story of the development of satellite communication. In 1955 President Eisenhower announced the USA's intention to launch a satellite. But it was the Soviet Union, which launched the first satellite in 1957: Sputnik I. After Sputnik's launch it became evident that the Cold War was also a race for leadership in the application of state-of-the-art technology to defence. As the US Department of Defence encouraged the formation of high-tech companies, it laid the ground to Silicon Valley, the hot spot of the world's computer industry. In the same year the USA launched their first satellite - Explorer I - data were transmitted over regular phone circuits for the first time, thus laying the ground for today's global data networks. Today's satellites may record weather data, scan the planet with powerful cameras, offer global positioning and monitoring services, and relay high-speed data transmissions. But up to now, most satellites are designed for military purposes such as reconnaissance.

Neural network A bottom-up artificial intelligence approach, a neural network is a network of many very simple processors ("units" or "neurons"), each possibly having a (small amount of) local memory. The units are connected by unidirectional communication channels ("connections"), which carry numeric data. The units operate only on their local data and on the inputs they receive via the connections. A neural network is a processing device, either an algorithm, or actual hardware, whose design was inspired by the design and functioning of animal brains and components thereof. Most neural networks have some sort of "training" rule whereby the weights of connections are adjusted on the basis of presented patterns. In other words, neural networks "learn" from examples and exhibit some structural capability for generalization.
