What is the main conflict in The Four Loves by C. S. Lewis?

C.S. Lewis, the author of The Four Loves, says some people are glad the English language uses both the words "love" and "like." He says his own generation was told not to say "I love strawberries," but to use the work "like" in that instance. However, most people still use the word love in that context. In the book "The Four Loves," Lewis will take the reader on a quest to discover and explore the various types of love felt, given, and received by humans. Lewis talks about loves in terms of affection, friendship, Eros, and charity. He goes into depth on each subject, but his true message seems to be that the four are almost always intertwined and that they are at their most intense and satisfying level when they are connected to a love for God. Charity, according to Lewis, is the highest form of love. In that case, people love without any personal attraction. In the case of all other types of love, there is some attraction—some reason the person cares for another.
