In 1914 he published a book called The Psychopathology of Everyday Life.This book goes a long way towards explaining some of the strange behavior of normal，sane3people.
A glance at Freud's chapter headings will indicate some of the aspects of behaviour covered by the book：
Forgetting of proper names
Forgetting of foreign words
Childhood and concealing memories
Mistakes in speech
Mistakes in reading and writing
Broadly，Freud demonstrates that there are good reasons for many of the slips and errors that we make.We forget a name because，unconsciously，we do not wish to remember that name.We repress a childhood memory because that memory is painful to us.A slip of the tongue or of the pen4betrays a wish or a thought of which we are ashamed.

弗洛伊德的精神病理學
當弗洛伊德在研究精神病案例時，形成了自己的精神分析法體係。他仔細研究了病人生活的細節，發現疾病總可以在病人自身的某些特別問題或內心衝突中找到根源。但他同時也發現，在精神病人身上才可觀察到的精神病，在正常人身上也有較輕程度的體現。這使他意識到正常人與神經病患者之間的界限不像人們過去認為的那樣清晰。
1914年他發表了《日常精神病理學》一書。這本書用了許多筆墨解釋了神智健全的正常人的一些奇怪行為。
瀏覽該書的章節目錄，它顯示了書中涉及的人類行為的某些方麵：
忘記正確的名稱
忘記外語詞彙
兒童時期和潛藏的記憶
言語中的錯誤
讀寫錯誤
廣泛地說，弗洛伊德論證了我們的許多失誤和錯誤都有因可究。我們忘記了某個姓名，因為潛意識裏我們不願記住它。我們壓抑一段童年的記憶，因為它對我們來說很痛苦。一個口誤或筆誤泄漏了我們認為羞恥的願望或想法。

催眠術
Hypnosis1 refers to a complex phenomenon2 that cannot even be described in a few words and that is still harder to define.Hypnosis is used by medical men to study their patients problems and to relieve3 symptoms such as pain.
