The birth date of logistics (formalized theory of thought) is considered to be 1879, when G. Frege (1848/1925) published his Begriffsschrift (Eine der arithmetischen nachgebildete Formelsprache des reinen Denkens) in Halle. He wanted a “pure thinking” but in a formula language modeled after mathematics. In the meantime, logistics has become a kind of proliferation and many who never had the time to familiarize themselves with logistics have the impression that their natural thinking ability does not really mean that much.
Yet the ancient natural logic is more vital than ever! The purpose of these Elements of Logic is to thoroughly acquaint you with the natural fact, inherent to every human being gifted with common sense, namely: correct observation and reasoning. Far from formulaic language but close to life. It will become apparent that your natural thinking is a more complicated mechanism than you might imagine.
In order to develop a clear view of this, this book is divided into a number of very small subdivisions that are not difficult in themselves but that will allow you to gradually gain an overview of the whole. And what is yet another reason to tackle this work is the fact that it does not avoid a number of current issues and clearly demonstrates the practical usability – for example in self-study or in discussion meetings – of the ancient logic.
