Spinozism (also spelled Spinoza-ism or Spinozaism) is the monist philosophical system of Baruch Spinoza which defines " God" as a singular self-subsistent substance, with both matter and thought being attributes of such.
In a letter to Henry Oldenburg Spinoza wrote: "as to the view of certain people that I identify god with nature (taken as a kind of mass or corporeal matter), they are quite mistaken". For Spinoza, our universe (cosmos) is a mode under two attributes of Thought and Extension. God has infinitely many other attributes which are not present in our world. According to German philosopher Karl Jaspers, when Spinoza wrote "Deus sive Natura" (God or Nature) Spinoza meant God was Natura naturans not Natura naturata, that is, "a dynamic nature in action, growing and changing, not a passive or static thing."

This system is a labyrinth, one lane of which would lead you to Spinozism, another to Stoicism, another to chaos.
To his mind, Spinozism was essentially de-terminist: all creation is the product of the unavoidable laws which govern the universe and organizes matter into pre-programmed forms.
