I understand this from the standpoint of issues of faith, such as the existence of God, or the belief that God created the world, and other things that can't really be observed or proven.“I do not seek to understand in order that I may believe, but I believe in order to understand.” -Anselm
But do we, or could we, actually live by this idea in everyday life? It seems to me that belief follows after understanding in many ways in our daily life. I don't just believe something is the case until I actually have learned to understand it. Belief without understanding seems irrational. We don't really trust something, or someone, until we have had enough knowledge and experience to warrant that trust.
Of course this begs the question of whether we ever really know something or someone perfectly, and probably there is always eventually a measure of belief/trust, or else we probably could not function in life.
Thoughts?
