There is no such thing as free will in the mental sphere or chance in the physical world.

Context

“There can be only one Being who is wholly positive, and He must be absolutely infinite. Hence Spinoza is led to a complete and undiluted pantheism. Everything, according to Spinoza, is ruled by an absolute logical necessity. There is no such thing as free will in the mental sphere or chance in the physical world. Everything that happens is a manifestation of God’s inscrutable nature, and it is logically impossible that events should be other than they are. This leads to difficulties in regard to sin, which critics were not slow to point out.” source
