Emily Dickinson Lexicon

HIM-SELF', pron. [him and self.]

1. In the nominative or objective case.
2. He; but himself is more emphatical, or more expressive of distinct personality than he. With shame remembers, while himself was one / Of the same herd, himself the same had done. Denham.
3. When himself is added to he, or to a noun, it expresses discrimination of person with particular emphasis. But he himself returned from the quarries. Judges iii. But God himself is with us for our captain. 2 Chron. xiii.
4. When used as the reciprocal pronoun, it is not usually emphatical. David hid himself in the field. 1 Sam. xx.
5. It was formerly used as a substitute for neuter nouns; as, high as heaven himself. [This use is now improper.]
6. It is sometimes separated from he; as he could not go himself, for he himself could not go.
7. Himself is used to express the proper character or natural temper and disposition of a person, after or in opposition to wandering of mind, irregularity, or devious conduct from derangement, passion or extraneous influence. We say, a man has come to himself, after delirious or extravagant behavior. Let the man alone; let him act himself. By himself, alone; unaccompanied; sequestered. He sits or studies by himself. Ahab went one way by himself, and Obadiah went another way by himself. 1 Kings xviii.
