Pessimism/Optimism, Reason/Faith

Reason breeds pessimism and Faith breeds optimism.

Let me give you some reason: attachment to anything that can die, will lead to sadness if its death precedes yours.  That includes everything: power, people, ideals....even relationships

So why be attached to anything?  Because without attachment, there is no purpose; and without purpose, there is no happiness.  A struggle for what gives us happy feelings...Even if that struggle is in vain.

Faith, on the other hand, is looking forward with Hope to things that are Good.  Like God.  Like Salvation / Eternal Life / Eternal Happiness (in the now undying things)
