Emotion
EMO'TION, noun [Latin emotio; emoveo, to move from.]
1. Literally, a moving of the mind or soul; hence, any agitation of mind or excitement of sensibility.
2. In a philosophical sense, an internal motion or agitation of the mind which passes away without desire; when desire follows, the motion or agitation is called a passion.
3. Passion is the sensible effect, the feeling to which the mind is subjected, when an object of importance suddenly and imperiously demands its attention. The state of absolute passiveness, in consequence of any sudden percussion of mind, is of short duration. The strong impression, or vivid sensation, immediately produces a reaction correspondent to its nature, either to appropriate and enjoy, or avoid and repel the exciting cause. This reaction is very properly distinguished by the term emotion
Emotions therefore, according to the genuine signification of the word, are principally and primarily applicable to the sensible changes and visible effects, which particular passions produce on the frame, in consequence of this reaction, or particular agitation of mind.
