s/ From the Notes of Alice Ambrose & Margaret MacDonaldPhilosopher Ludwig Wittgenstein had an enormous influence on 20th-century philosophy even tho only one of his major works, the famous Tractatus Logico-Philosophicus, was published in his lifetime. Beyond this publication the impact of his thought was mainly conveyed to a small circle of students thru his lectures at Cambridge University. Fortunately, many of his ideas have survived in both the dictations that were subsequently published & the notes taken by his students, among them Alice Ambrose & the late Margaret Macdonald, from 1932 to 1935. These notes, now edited by Professor Ambrose, are here published, & they shed much light on Wittgenstein's philosophical development. Among the topics considered are the meaning of a word & its relation to common usage, rules of grammar & their relation to fact, the grammar of 1st person statements, language games & the nature of philosophy. This volume is indispensable to any serious discussion of Wittgenstein's work.
