In C.S. Lewis's book "The Four Loves," he explores the concept of different types of love, emphasizing the distinction between erotic love and friendship. He argues that while erotic love is focused on physical attraction and the desire for intimacy, friendship dives deeper, valuing the essence of individuals beyond their physical appearance. This suggests that true companionship involves revealing one's inner self and personality, leading to a more profound connection.

Lewis's quote, "Eros will have naked bodies; Friendship naked personalities," encapsulates the idea that erotic relationships often prioritize the physical, whereas friendships require vulnerability and honesty. In genuine friendship, individuals connect through their thoughts, values, and emotions, revealing their true selves without pretense. This relationship fosters a unique bond that transcends the superficial aspects of attraction, highlighting the importance of emotional intimacy.
