The Blue and Brown Books

New York: Harper & Brothers, 1958. Cloth. Very Good +/Very Good +. A crisp, very sharp copy of the 1958 1st American edition of Wittgenstein's "Preliminary Studies for the 'Philosophical Investigations' Generally Known as the Blue and Brown Books". Tight and VG+ (light soiling to the pastedowns, very light offsetting at the endsheets) in a bright, price-clipped, VG+ dustjacket, with just a touch of very light staining at the spine crown and a tiny amount of light creasing to the foot of the spine. Still though, attractive and very presentable. Wittgenstein's "talks to his classes at Cambridge in the nineteen-thirties" became "the 'Blue Book' and the 'Brown Book', which he dictated in English to students between 1933 and 1935" and which "represent the teaching which accomplished what is sometimes called a 'revolution in philosophy'" (Walter Kaufmann).
