Chapter X: Fortune's Smile.
Lewis' vacations became better as the aged. His brother was in the army during WWI and his leaves were good times. He had a good friend with whom he shared common interests and who taught him to appreciate beauty in the small things in nature. He began to read the old English authors and enjoy them. The relationships with his father were the same. To satisfy his father, he was confirmed and took communion, even though he did not believe. He regrets that act.
Chapter XI: Check.
During this time Lewis' experiences of Joy became more elusive. He tried to generate them, usually without success. And when he did find Joy, it was because he forgot about trying.
He lived in two separate worlds--a world of the imagination and a rational world. "I do not think the resemblance between the Christian and the merely imaginative experience is accidental. I think that all things, in their way, reflect heavenly truth, the imagination not the least."
He was as amoral as a person could be and he tried to find Joy through sex, but it was not there. He even became interested in the occult and magic, but rejected that as well.
He picked up a Phantastes by George MacDonald and found something which he couldn't describe (and didn't really describe in the book) which was elusive, but not grazable. He calls it in retrospect holiness. He says that night his imagination was baptized.
