Highly recommended for its informative Introduction, less-archaic translations, and Endnotes. Page 260 Endnote 1: "Spinoza's definitions are of the kind now commonly called 'stipulative'; that is, they tell the reader how Spinoza proposes to use certain words. Spinoza is not concerned (as a Dictionary is concerned) to describe the standard uses of words. His Purpose, as he observes in the Ethics (E3:Def.XX.Expl.) is to explain, not the meaning of words, but the nature of things. One may compare what is done by scientists, when they introduce new technical terms, or give old words a new sense, with a view to explaining what it is that interests them."
