The Last Unknowns

This book is very cerebral and I loved it for that .....It really exercised my grey matter ....I'll be using it for an intellectual workout again in the future and will be utilizing some of the very profound questions in conversations with others who enjoy engaging their brain cells in philosophical activity. Kudos to Mr.Brockman for organizing such a wide array of genius and for having the genius idea to do so to begin with ,I feel smarter already for reading this compilation of brilliance .
