NECESSITY S PINOzA ARGUES THAT although we are con-scious of our volitions and desires, we are not free. For Spinoza, everything happens out of necessity. Since everything that happens in our minds is determined by some cause (which has been itself determined by another cause), there is no place in Spinoza’s system for free will.
