How do we know what we "know"? How did we ï¿½as individuals and as a society ï¿½ come to accept certain knowledge as fact? In Human Knowledge, Bertrand Russell questions the reliability of our assumptions on knowledge. This brilliant and controversial work investigates the relationship between ï¿½individualï¿½ and ï¿½scientificï¿½ knowledge. First published in 1948, this provocative work contributed significantly to an explosive intellectual discourse that continues to this day.
