The very condition of having Friends is that we should want something else besides Friends. Where the truthful answer to the question "Do you see the same truth?" would be "I see nothing and I don't care about the truth; I only want a Friend," no Friendship can arise - though Affection of course may. There would be nothing for the Friendship to be about; and Friendship must be about something, even if it were only an enthusiasm for dominoes or white mice. Those who have nothing can share nothing; those who are going nowhere can have no fellow-travellers.
C.S. Lewis asserts that true friendship requires a shared interest beyond mere companionship. He emphasizes that friends must have a common ground or enthusiasm to bond over; otherwise, their relationship cannot deepen into true friendship, even if they feel affection for one another. Without a mutual interest or something meaningful to engage with, individuals cannot truly connect as friends.
Lewis suggests that friendships are enriched by shared experiences or passions. If two people lack a mutual pursuit or haven’t a shared destination in life, they cannot engage in the journey of friendship meaningfully. In essence, having friends is contingent upon desiring something greater together, underscoring the importance of common interests in forging deep connections.
