THE INTERPRETATION OF DREAMS

Flectere si nequeo Superos, Acheronta movebo

In 1909，G. Stanley Hall invited me to Clark University, in Worcester, to give the first lectures on psychoanalysis.In the same year, Dr Brill published the first of his translations of my writings, which were soon followed by further ones.If psychoanalysis now plays a role in American intellectual life, or if it does so in the future, a large part of this result will have to be attributed to this and other activities of Dr Brill's.

His first translation of The Interpretation of Dreams appeared in 1913. Since then, much has taken place in the world, and much has been changed in our views about the neuroses.This book, with the new contribution to psychology which surprised the world when it was published（1900），remains essentially unaltered.It contains, even according to my present-day judgment, the most valuable of all the discoveries it has been my good fortune to make.Insight such as this falls to one's lot but once in a lifetime.
