Nietzsche said that there are two types of people: those who want believe, and those who want to know.
More recently, it’s been suggested that the distinction between the two may be related to intelligence. Now I know how condescending that sounds, but think about how the mind works: stitching together a constant stream of information coming from the senses and presenting it to us in a form that becomes our individual “reality”.
Where the brain cannot stich together information from the senses, it relies on memory, or knowledge. It fills in the gaps as best it can to create the illusion of something solid, so we can make decisions that will keep us alive.
