What ego defense mechanism did A. A. Brill emphasize?

A. A. Brill emphasized sublimation as an ego defense mechanism, highlighting its role in facilitating healthy psychological functioning. Sublimation is the process by which socially unacceptable impulses or idealizations are transformed into socially acceptable actions or behaviors, often resulting in constructive outcomes. For example, instead of expressing aggressive impulses through harmful actions, an individual might channel that energy into sports, art, or other creative pursuits. This mechanism allows individuals to deal with their emotions and impulses in a way that can contribute positively to society, promoting personal growth and well-being.

Brill viewed sublimation as a mature defense mechanism that reflects an individual's ability to adapt and thrive. By utilizing sublimation, individuals can achieve their goals and fulfill their desires in ways that are more acceptable to themselves and the community, fostering resilience and psychological health.
