Final answer:
Self-awareness and self-acceptance are considered key to knowing and accepting others, as advocated by philosophers such as Socrates and Confucius, and as implied in Erik Erikson's stages of development. Option C is correct.
Step-by-step explanation:
To answer the question of how one should know and accept others, we can consider the teachings of various philosophers and thinkers. Socrates, a proponent of self-examination, advised individuals to investigate their own beliefs and knowledge, to appreciate the limits of their knowledge, and to strive for consistency in their thoughts. This aligns with option C, which emphasizes working towards self-awareness and self-acceptance, and suggests that through understanding oneself, one can better understand and accept others.
The quote, 'To know what you know and what you do not know, that is true knowledge,' by Confucius, also points to the importance of self-knowledge as a path to understanding and accepting others. Moreover, self-reflection is highlighted in the Vedic texts as a way to understand not just oneself but also the nature of the world, correlating with self-awareness leading to a broader acceptance of others.
Erik Erikson's stages of development further support the idea that personal growth and development play a role in how we relate to others, as seen in the challenge of overcoming despair to achieve integrity in older age. Thus, the teachings across historical and cultural contexts converge on the answer: Option C, Work towards self-awareness and self-acceptance, is the best way to know and accept others.
