This book presents the website exactphilosophy.net, as of 2016. Written by a Swiss physicist, it contains lots of beautiful novel ideas, inspired by nature and physics, ancient and modern philosophy, as well as by astrology, the I Ching and more... Please note that this book does not yet present these ideas in a way and format suitable for most readers. Instead, it addresses anyone with a mind free enough to think outside of some of the usual ""boxes"", paired with imagination and also a more scientifically critical mind in the end, as implies the ""exact"" in exactphilosophy. In essence, first ""elements"" are tentatively defined from first principles, inspired mostly by Kant, then some correlations between these abstractly defined ""elements"" and the ancient Greek elements, as well as with the 8 trigrams of the Chinese I Ching, are revealed, and finally a simple model of the 12 star signs in terms of transformations of the elements is revealed and explored.
