Consider the following thought experiment:
Suppose there is an experience machine that would give you any experience you desired. Superduper neuropsychologists could stimulate your brain so that you would think and feel you were writing a great novel, or making a friend or reading an interesting book. All the time you would be floating in a tank, with electrodes attached to your brain. Should you plug into this machine for life, pre-programming your life’s experience?
This, obviously, is a rhetorical question. And I would assume that for most people answer is a curt “No”. We think that actually playing a game is somehow superior to a mere (stimulated) experience of playing a game; even if the brain attached to electrodes can’t tell the difference. Doing something is better than the experience of doing. We just don’t want to experience things, we want to do thing and be someone.
Here’s another scenario: Person A mistakenly believes that his favorite team won the game last night, and person B correctly believes that his favorite team won. [Assume that there are no consequences of the mistaken belief.] Even if there is no difference in their subjective degrees of happiness, if you had to choose between the two, you would choose to be person B. In terms of well-being of a person, the illusion-based happiness is perceived inferior to the fact-based happiness. You don’t want to rejoice for your home-team just for the sake of being happy. You want your home-team to have actually won as well. Otherwise, it’s just not the same. (Again, even if there’s no subjective difference in what we feel from the inside.)
“Happiness, at least if it is understood to correspond to well-being, turns out not to be all in the head”, writes Leo Katz in his intriguing book Ill-gotten Gains: Evasion, Blackmail, Fraud, and Kindred Puzzles of the Law, from which these scenarios are taken. He quotes an Oxford philosopher to elaborate more on this:
I prefer, in important matters of my life, bitter truth to comfortable illusion. Even if I were surrounded by consummate actors able to give me sweet simulacra of love and affection, I should prefer the relatively bitter diet of their authentic reactions. And I should prefer it not because it would be morally better, or more noble, but because it would make for a better life for me to live.
… because it would make for a better life for me to live. Touché!
The pedigree of experience matters – that’s the lesson from these thought experiments. But alas, when it comes to the belief in God, the majority of us seem to prefer the comfortable illusion — there’s an after-life, God is watching and helping us etc. — to the bitter truth that there’s no God, and we are on our own.
