The most pure people on the pursue of truth and life get generally entangled, sooner or later, by the on going of days passing and habits forming.  This people, the more pure ones, want to believe (or do believe already) most of all in something, but with time, slide generally to an opposite direction, starting to believe in what remains - because if it persists they will think there is truth in it...

The weak die young for they're afraid of getting strong.
