MALEBRANCHE, NICOLAS (1638-1715). De la recherche de la veritè ou l'on traitte de la nature de l'esprit de l'homme, & de l'usage qu'il en doit faire pour éviter l'erreur dans les Sciences. Paris: Chez André Pralard, 1674. First Edition. The first and most important work of Malebranche, "De la recherche de la veritè" established him as the premier Cartesian philosopher of his day. 12mo, xl + 420pp. Newly rebacked in blind-tooled calf preserving original sprinkled calf boards, gilt lettering on spine, five raised bands. Small tear to lower center of title-page, two library stamps on title-page, library stamp on page 137, lacking diagram.
But 420 pp. seems short; I don't have any critical apparatus with me, but as I recall the Search was published in two parts; if it's a one-volume first edition from 1674, it isn't the full Search after Truth but just books 1 to 3. Then you'd also have to hunt down and buy me the 1675 edition, of books 4-6, to match, and that just doesn't seem fair to ask. ;)
