Chapter 9 in Mere Christianity is called “Charity.” I don’t have a whole lot to say on this chapter as it was quite short.
C.S. Lewis begins by saying “Do not waste time bothering whether you ‘love’ your neighbor; act as if you did.” Actually, psychology suggests that we form our opinions of people before we’re even conscious of doing so. It also shows that negative impressions are more powerful than positive ones, so it’s hard to make yourself like someone after you decide that you dislike them. You cant simply make yourself like someone by acting as though you do.
He then says “If you injure someone you dislike, you will find yourself disliking him more. If you do him a good turn, you will find yourself disliking him less.” I don’t think emotions work this way either. Where is the evidence to suggest that this is true?
And his final argument is “They are told they ought to love God. They cannot find any such feeling in themselves. What are they to do? The answer is the same as before. Act as if you did. Do not sit trying to manufacturer feelings. Ask yourself, ‘If I were sure that I loved God, what would I do?’ When you have found the answer, go and do it.” That’s manufacturing feelings. It also sounds a bit like Pascal’s Wager to me. It makes no sense to try and “fake it till you make it” in this case.
