Final answer:
The stage of moral development where being good is equated with pleasing others and conforming to society's norms is known as the Conventional level in Lawrence Kohlberg's theory.
Step-by-step explanation:
Kohlberg's Stages of Moral Development
According to Lawrence Kohlberg's theory of moral development, the description of being good as whatever pleases others, adopting a conformist attitude, and determining right from wrong by majority fits within the Conventional level. Specifically, it aligns with the 'Interpersonal Concordance' stage, where morality is predominantly dictated by societal norms and the desire to gain approval from others. In this stage, individuals often conform to what they perceive as society's expectations to maintain relationships and societal order.
It is during adolescence that this Conventional level of moral reasoning typically develops. Individuals in this stage become more aware of the feelings of others and societal laws, which guide their understanding of morality, as opposed to the self-centered reasoning found in the pre-conventional stage or the principled reasoning of the post-conventional stage where abstract principles guide moral judgments, which could contradict societal or legal norms.
