agreed, truth is relative and obsolete quite honestly. but in order for there to be truth, there has to be non-truth, or a lie. truth is also dependent upon the situation. for example, a buddy of mine asked his father, a well known pastor in our area, this question: if something is 99 cents, and i tell you it is a dollar, am i lieing? his father's response after a few seconds of thought was this: well, if you told me that in an attempt to decieve me it would be a lie, but if it were as intended as honest as an answer as if i asked if you woke up this morning and you said yes which is invariably true the no, it would not be a lie.
my point is that i think truth is a relative term dependant upon the situation.
