_One can will to remember or recall anything forgotten_. I will not be responsible that this will invariably succeed at the first time, but that it does often follow continued determination I know from experience. I believe that where an operator hypnotizes a subject it very often succeeds, if we may believe the instances recorded. And I am also inclined to believe that in many cases, though assuredly not in all, whatever is effected by one person upon another can also be brought about in one's self by patience in forethought, self-suggestion, and the continued will which they awaken. _We can revive by this process old well-nigh forgotten trains of thought_. This is difficult but possible. It belongs to an advanced stage of experience or may be found in very susceptible subjects. I do not belong at all to the latter, but I have perfectly succeeded in continuing a dream; that is to say, I have woke up three times during a dream, and, being pleased with it, wished it to go on, then fallen asleep and it went on, like three successive chapters in a novel. _We can subdue the habit of worrying ourselves and others needlessly about every trifling or serious cause of irritation which enters our minds_. There are many people who from a mere idle habit or self-indulgence and irrepressible loquacity make their own lives and those of others very miserable--as all my readers can confirm from experience. I once knew a man of great fortune, with many depending on him, who vented his ill-temper and petty annoyances on almost everyone to whom he spoke. He was so fully aware of this failing that he at once, in confessing it to a mutual friend, shed tears of regret. Yet he was a millionaire man of business, and had a strong will which might have been directed to a cure. All peevish, fretful and talkative, or even complaining people, should be induced to seriously study this subject. _We can cure ourselves of the habit of profanity or using vulgar language_. No one doubts that a negro who believes in sorcery, if told that if he uttered an oath, _Voodoo_ would fall upon him and cause him to waste away, would never swear again. Or that a South Sea Islander would not do the same for fear of _taboo_. Now both these forms of sorcery are really hypnotizing by action on belief, and Forethought aided by the sleep process has precisely the same result--it establishes a fixed idea in the mind, or a haunting presence. _We can cure ourselves of intemperance_. This was, I believe, first established or extensively experimented on by Dr. CHARLES LLOYD TUCKEY. This can be aided by willing that the liquor, if drunk, shall be nauseating.
