Abstract

Avicenna and Spinoza defend the necessity of causality. In some cases, Avicenna, takes it evident and in other cases argues for it. Spinoza takes it evident, decisively. All the Avicenna’s arguments beg the question. On the other hand, not only the necessity of causality is not evident, but also non-necessity is intuitive and evident. The author believes that the discussion of the necessity of causality originates from the separation between necessity and possibility, and the insistence on the justification of the generation of entities only by these two concepts, while these two concepts can only explain the difference between entities, and we need another concept to explain createdness.
