Explain further how this principle is controlled by the id and is a natural instinct from birth. Although expressed through the id, the ego helps to suppress painful experiences and situational reactions. Fouché and Holz (2015) added, whether angry, in physical or emotional pain, or hungry, the pleasure principle is controlled with impulses and immediately attempts to protect and gratify needs, impulses, and desires. Otherwise, the reality principle seeks to satisfy the id's desire in social and real-life contexts. Although governed by the ego, this principle allows people to function within limits and acceptable behaviors in various social groups, situations, and environments (Fouché & Holz, 2015). Similarly, Knight (2014) emphasized that healthy psychological growth helps one understand the differences between immediate gratification and impulses and the consequences of one's impulses.
