The book consists of three instructive papers written by Wilhelm Vossenkuhl. Each paper is deeply concerned with one major issue in analytical philosophy and discussed with the thoughts, concepts, and approaches which Wittgenstein used to deal with it. This book is not suitable for someone recently introduced o the field but can be helpful. The translation of Dr. Malek Hosseini is not as well as his other works especially related to Wittgenstein's philosophy.
