I'm just wondering, I know that this is a big topic in regards to religion. Some people say that religion has to be true because some people truly feel a need for their faith, and in their mind, having a need that cannot be satisfied is impossible, therefore the religion has to be true. CS Lewis alludes to this concept when he writes that if I should find a need my world cannot satisfy, then I probably was not made for this world (paraphrase). But is this really true? Is it possible to need something that cannot be attained or satisfied? And is there a difference between needing something and desiring something?
