Why, indeed

I was part of a conversation with the owner of a Christian bookstore catering to homeschoolers. In her area she meets a number of parents who come in looking for curriculum but specifying, very definitely, they do not want materials with a Christian flavor to them, and do not want their children exposed to Christian teaching.

She told me she is in business to serve whomever needs help, so she guides them to books which meet their specification. She mused, though, over how often these same parents will ask her, "Why is all the good stuff Christian?"

I read a similar comment online this weekend, where a mother in Arizona is starting a homeschool organization for Pagans. She mentions as part of her inspiration that she had attended a high school graduation presented by Arizona Families for Home Education, saying "the ceremony was beautiful and seeing so many homeschoolers graduate was amazing ..."

Why indeed. My friend's response about the benefit of starting with Truth as your foundation was said in love, and accurate. The question which came to my mind, though, was what prevents the same question from rising in relation to any other field -- art, music, engineering, medicine, literature. Why not?
