"les Mots", or "Words", is Jean-Paul Sartre's autobiography about his childood, with a strong emphasis on literature; an emphasis which is only natural, since little Sartre grew up with them before he began writing himself (pun intended).
Accordingly, the book is divided into two parts: "To Read" and "To Write".
If you can read French, then please do yourself a favour and read this wonderful text. It is so good, it actually made me enjoy writing French prose, which is something no other text before ever did, and about the only other French text that I can remember which had an effect of "wow, that's well written!" on me was "les Liaisons Dangereuses" by Laclos.
"Les Mots" is a thrilling read, with insights so profound and witty that I enjoyed every page of it. I generally love Sartre's writings, and this is no exception; it just may have a little something more, in the sense that, for all I know, it is the only explicitly autobiographic book he wrote.
I can't recommend this book enough.
