Originally published in 1875, this book discusses thinking and language and traces the development of different pscyological approaches, assessing their theoretical significance and the experimental evidence behind them. It ends by drawing together the various lines of argument to arrive at some general conclusions about language and thought, since it clearly emerges that the two are inextricably linked.
