Russell's An Inquiry into Meaning and Truth is a well-written book with extra in-depth details and careful examining.
This book exposes reader to a wide array of topics, which most of the time found going together, which are epistemology, philosophy of language, logic, and a hint of metaphysics.
So if the reader is not a philosophy student, s/he can still read this book to gain intermediate knowledge of philosophy of language, given that s/he has already been exposed to fundamental materials of the same topic.
I am not a philosophy student, neither a native English speaker, I'm just a philosophy-geek - person who is fascinated with the study of philosophy and complex writing.
