Children are the only bold philosophers. And bold philosophers will always be children. So you're right, it's a child's question, just as it should be.
They say that childhood forms us, that those early influences are the key to everything. Is the peace of the soul so easily won? Simply the inevitable result of a happy childhood. What makes childhood happy? Parental harmony? Good health? Security? Might not a happy childhood be the worst possible preparation for life? Like leading a lamb to the slaughter.
