CS Lewis popularized an argument that was in use since the middle ages. It states:
Every natural or innate desire we experience points to something real. We have a desire for perfect happiness, a perfect guide: therefore, this happiness and guide do exist.
This demonstrates the existence of heaven and God, and it has merit. Why would we desire something impossible? What is the benefit, evolutionarily or otherwise, to perpetual disappointment? We innately have desires that will never be fulfilled in this world. We want perfect safety, comfort, knowledge, and the very fact we want this universally promises that there must be some cause that ties all humans together under this desire.
With no explanation for the existence of a desire that does not also have a fulfilment, as Lewis says, we are leaded to the conclusion of a divine hand and a sanctuary.
Can this be taken beyond just the topic of God? Are there ideals that surface inevitably, in countless cultures indepently across the world? What might we learn from them?
Before we are told what is, what is it humanity wants?
