A recent post in the blog site "Atheist Revolution" discussed the topic: Would You Rather Be Happy and Wrong or Unhappy and Right? Personally, I think that it's not only wrong to hold on to false beliefs just because they make a person happy, it's also unhealthy. I think that theism falls into this category. And because the delusion of god-belief is so predominant in places such as the U.S. and for that matter especially here in the Philippines, millions of people are living in a fantasy world. Sure, there's a lot of subjectivity in deciding whether a particular belief is true or false. But so many traditional religious tales, especially the Scriptures, are so patently absurd that there's really no room for debate about whether there is any truth to them. Yet believers accept them just because "it's in the bible".
What's behind this mass delusion? Brainwashing, obviously (actually "socialization" as my sociologist cousin corrected me). Beginning at an early age, most theists have their beliefs instilled into them by their parents and religious leaders. So by the time they're adults, they are almost totally conditioned, Yet somehow, some of them (myself included) whether by exposure to new ideas or a by a traumatic event eventually lose our faith in these ridiculous notions and learn to accept the reality that there is no proof that a supreme being exists, let alone intervenes in our lives.
As for me, am I any less happy for losing the crutch of false belief? Not at all. Delusions are in the end really mental burdens, and because atheism has enabled me to shed that load, it has also simplified my outlook on life—and death too for that matter. There is no evidence for an afterlife which means of course that when we die, it's lights out forever. Well, that inevitability doesn't bother me in the least. As Mark Twain aptly put it: "I do not fear death. I had been dead for billions of years before I was born, and had not suffered the slightest inconvenience from it".
Was I happy when I was a believer? No. Belief in a God actually made life more difficult because it wasted my time by diverting part of my attention from my problems to this mythical entity who I hoped would help me, when I should have been fully focused on solving matters at hand instead.
The universe is indifferent to human needs and wants, and randomness happens in our lives all the time. But to the extent that there's no evidence for the existence of a God who manipulates our fates like a puppeteer and whom we must obey lest we be punished, this is one less barrier in striving to achieve personal growth and happiness.
And that sounds right to me.
