C.S. Lewis answering the question- which of the world’s religions is most likely to give it’s followers the greatest happiness:
Which of the religions of the world gives to its followers the greatest happiness? While it lasts, the religion of worshipping oneself is the best.
I have an elderly acquaintance of about eighty, who has lived a life of unbroken selfishness and self-admiration from the earliest years, and is, more or less, I regret to say, one of the happiest men I know. From the moral point of view it is very difficult! I am not approaching the question from that angle. As you perhaps know, I haven’t always been a Christian. I didn’t go to religion to make me happy. I always knew a bottle of Port would do that. If you want a religion to make you feel really comfortable, I certainly don’t recommend Christianity. I am certain there must be a patent American article on the market which will suit you far better, but I can’t give any advice on it. (God in the Dock p.58)
Perhaps our problem is that we often consider happiness and comfort to be synonymous. On this way of thinking, my pursuit of happiness boils down to something like, ‘do what feels good.’ This is how you trip over your own happiness and stumble into an existential hangover.
What if, as Lewis recommended elsewhere, we look beyond what lies ‘under the sun’?
“We are half-hearted creatures, fooling about with drink and sex and ambition when infinite joy is offered us, like an ignorant child who wants to go on making mud pies in a slum because he cannot imagine what is meant by the offer of a holiday at sea. We are far too easily pleased.” (Weight of Glory)
The first quotation shows that our view of what constitutes happiness can be shallow and banal. The second reminds us that our pleasures are echoes of a greater reality spoken of by the Apostle:
“For this light momentary affliction is preparing for us an eternal weight of glory beyond all comparison, as we look not to the things that are seen but to the things that are unseen. For the things that are seen are transient, but the things that are unseen are eternal.” (2 Cor. 4:17-18 ESV)
Far too easily pleased indeed.
