in living organisms, in human societies and culture, there are noticeable similarities and structures, which manifest themselves in a similar way. Language, mathematics, or the structural rules of native tribal societies all show similarities. A living organism is neither a mechanical machine, as Descartes believed, nor a system of chemicals and energy; life is above all an organisation of molecules, cells and organs governed by the exchange of information. Nothing is unchangeable or constant; there is, however the ability to regulate and balance out the fluctuations which occur. A warm-blooded creature does not need to maintain its constant bodily temperature by protecting itself from external changes of temperature, as it is able to ‘monitor’ these changes and actively compensates for them. That is called feedback and it is not a chemical or energy link. It is an information link, albeit one carried out by means of chemicals or electricity. The concept of information has changed the world in our lifetime. It was not there eighty years ago. It, too, is mathematised and still closely connected to mathematics, but it is a different kind of mathematics. It is not concerned with measuring quantities; it deals with formulating the regularity of structures. In place of differential equations, algebra comes to the fore, as well as informational statistics. A good example is provided by the Markov chains – in each language, it is possible to determine the average word length or the probability of a given speech sound being followed by another. If we let a computer generate a random sequence of letters with the same statistical properties, the resulting text will not make sense, but it will, at a casual glance, strongly resemble writing in German or English. Information and the processing of it nowadays dominates not only administration and all levels of government, it also sustains a vast industry, as well as providing the foundations of molecular biology and genetics. Moreover, the concepts of structure and information have helped bring about interdisciplinary scientific projects and endeavours, often motivated by environmental concerns, perceiving nature, and the Earth, as a whole, something which frequently slips off the radar of the specialised disciplines. The aim of this ridiculously short summary of the ideological history of science is merely to demonstrate that ‘science’ today is anything but monolithic, that there is a constant flow of new ideas and concepts, which retroactively affect even everyday existence. In this way, science constantly touches on and grapples with philosophy, which should not only act as a nutrient medium for science, and provide new ideas, but which should also monitor the direction which science is taking.
