Philosophy

Number as the principle of the world: from the Pythagoreans and Plato to the question of why mathematics can describe nature at all.

1. 01Number theory + geometry = philosophyThe motto of this site. Joining analytical thinking in numbers with visual thinking in forms leads to questions that go beyond both.
2. 02The tetractys analogy tableThe four start figures alongside the fournesses of physics, philosophy, Hermeticism, Kabbalah, Freemasonry and religion. A comparison, partly explicitly speculative.
3. 03The tetractys in J. G. Herder's MetacritiqueHerder set a fourfold formula of categories against Kant's forms of intuition and explicitly called it a tetractys.
4. 04Giordano Bruno – the monad, number and figureThe philosopher burned in 1600 described the numbers from 1 to 10 as figures in a circle. Four points of agreement with the geometry of the tetractys.
5. 05Great thinkers on the structure of the worldFrom Pythagoras and Plato through Kepler and Newton to Planck and Dürr. How scientists thought about the order of the world.
6. 06Death and reincarnation – spirit and matterThe transmigration of souls was a core of Pythagorean teaching. What philosophy says about it and what research exists.
7. 07The true masterA parable about paper, interest and the four things of nature – about the right measure.
