Really, what is the truth?
I think that the true definition of the truth depends on the context.
The truth, according to Webster, is "the state of being the case". Basically, a truth cannot be something that is not right, such as "A cat's cradle is a bunch of string." In science, truths are not argued or disputed; they are accepted wholly as what is real. The truth and logic are the momentum behind science. Though it is understandable, that through these scientific truths, knowledge is acquired. From knowledge, one is meant to grow.
Religion doesn't need the truth.
Religion is based not on
knowledgeably sound solutions, but rather solutions that are spiritually and morally sound. What is morally true to one man, isn't necessarily the same as what is true to the next man over. Religion is based on the
individual's assumption of the facts, rather than a textbook written by a scientist who researched and found the truth to be indisputable. Religion can be disputable. Religion is always changing, unlike the concrete knowledge behind science.
By living in the twisted world of John's (Jonah?)
karass, the truth is taken in by the vacuum of
Bokononism and spun around into something unlike anything it was before. The
fomas, or harmless untruths, take control of a world so chaotic that no science can do it any good. The mysterious religion of Bo
konon, a religion based on falsities, becomes less terrifying and scandalous and more
relatable and acceptable as
Cat's Cradle reads on, especially to the pathetic citizens of San
Larenzo. San
Larenzo is a secretly
Bokononist nation, with a staggering population and abundant poverty. The San
Larenzon lifestyle is not one of glamour or material happiness. The only cares of the typical San
Larenzon are "fishing, fornication, and
Bokononism". It is understandable to relate to the San
Larenzo's desperate desire in a religion that is not logical as they live impoverished. The San
Larenzons do not need science to amend their painful existence, but rather an escape through a mystical religion to justify a worth of meaning. Such a hopeless and fruitless nation still prevailed prior to the ice-nine tragedy due to the San
Larenzon's secure belief system in lies.
Religion is needed for security.
Bokononism, though full of total and utter
malarky, gives security where science cannot. To live by the
foma as
Bokonon preaches is truly the solution to the menagerie of desperate characters in Vonnegut's world.
