 The fifth and final work of the "Opera Posthuma" is a grammar of the Hebrew language, "Compendium Grammatices Linguae Hebraeae".Spinoza's "Short Treatise on God, Man, and His Well-Being" - expressing opinions sharply conflicting with the dominant Calvinist theology of his time as with the Judaism practiced by the Amsterdam Jewish community - was not included in the Opera Posthuma.It was only published much later, on the basis of two Dutch translations of it, which were discovered about 1810."
