 Last but not least, we should not forget that Spinoza’s magnum opus carries the title Ethics. For him knowledge is not merely a theoretical achievement, as if we were solving conceptual puzzles for their own sake. For Spinoza, what is at stake in understanding anything, including thinking and knowledge, is a whole slew of practical goods: freedom, virtue, blessedness. Of the infinity of knowable things, Spinoza writes, he wants to write only about “those that can lead us, by the hand, as it were, to the knowledge of the human Mind and its highest blessedness” (E2pref).
