Having an ultimate purpose for our lives implies that there is a reason for our existence—in other words, some kind of intention and objective. Without an ultimate purpose we have no reason to exist, and we lack a profound meaning for our lives. This is the perspective of naturalism. It dictates that we merely spring from prior physical processes. These are blind, random and non-rational. The logical conclusion of this indifferent view on our existence is that we are riding on a sinking ship.
