Abstract
Spinoza holds that we can become free by recognizing that everything happens with necessity. His own reasons for this claim do not stand scrutiny. More promising appears the idea that he who considers things necessary is not subject to affects that deprive him of his freedom. On this line, however, recognizing necessity also destroys joy, contrary to Spinoza’s maxim ”Do good and be joyful”. More importantly, what is necessary may in fact be a reasonable object of affective reactions. Thus, Spinoza fails to support the enlightenment’s hope that knowledge brings freedom.
