Manipulation, an unscrupulous form of social influence, employs strategies such as coercion, persuasion, or emotional exploitation to achieve personal goals. Authors have examined its various aspects: Woodworth described it as a deliberate act within psychology, while Eddy criticized physical manipulation, promoting spiritual approaches over material ones.
Bolas applied the concept to the technical expertise required in glass-blowing, and Vivekananda associated it with control over the mind and body. Lytton raised questions about the morality of influencing others, and Massillon emphasized its damaging impact on moral autonomy. These varied viewpoints illustrate manipulation as a complex phenomenon, encompassing psychology, literature, and philosophy, and highlighting its lasting significance in human interactions.
