 All references to Spinoza’s Ethics start with E and Part number, followed by one or more of the following: ‘p’ for proposition, ‘alt’ for alternative, ‘app’ for appendix, ‘ax’ for axiom, ‘c’ for corollary, ‘d’ for demonstration, ‘def’ for definition, ‘L’ for lemma, and ‘s’ for scholium. Where useful, reference is added to the Latin Gebhardt edition as G followed by volume and page numbers. ‘NS’ refers to De Nagelate Schriften van B. D. S., a 1677 Dutch edition of Spinoza's writings.
