In the end, hope without truth is pointless. Illusions and delusions, no matter how comforting or grandiose, are the enemies of those who strive for integrity in their knowing and being. Statements such as "I like to think of the universe as having a purpose" or "The thought of an afterlife gives me peace" reflect mere wishes. These notions do not address the truth or falsity of there being purpose in the world or of our postmortem survival, because there is no genuine claim to knowledge: a warranted awareness of reality as it is. A hearty, sturdy and insatiable appetite for reality--whatever it might be--is the only engine for testing and discerning truth.
