With regard to truth, once again Truth is a fact that is governed by reality. It is a fact that gravity holds us to the earth, that I am sitting in a chair that electricity powers my lights. Another example of truth; "We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty and the pursuit of Happiness." As I have said many times before the truth is what stands along as our founding fathers put it "self-evident". Truth may be covered up by the cloak of evil and deception however it does not remove it from existence, and long after the ones holding on so tightly to the cloak have vanished the truth will still remain. In a world surrounded by so many cloaks it may be difficult to locate the wizard of oz but that does not mean that he is not there.

Two great quotes that I have always remembered ever since childhood:
"The truth points to itself" -Kosh
"No one here is exactly what they appear" -G'Kar

Also yes those seriously are from an old tv show. A joke I sometimes tell myself: all the knowledge in the word with no wisdom is the perfect definition of a knowledgeable fool they may know everything but they are no more useful than a book. Logically this leads people to say well knowledge is all over but where can wisdom be found? Well the best part of wisdom is that you require nothing but yourself! Knowledge you learn but wisdom you practice.

Interestingly enough the activity we are engaged in right now is one that propagates wisdom. Although it is gained though you it can always be nurtured though intelligent discourse. "And isn't it a bad thing to be deceived about the truth, and a good thing to know what the truth is? For I assume that by knowing the truth you mean knowing things as they really are." (Plato)

I end with yet another quote so sum up my statements, also note that I found these quotes after writing my response and thus my previous statements are not based off these quotes but my own personal understanding of the issue in question. I will say however that these are some powerful quotes that probably do a better job at the answer than my own words ever could.

"Somebody who only reads newspapers and at best books of contemporary authors looks to me like an extremely near-sighted person who scorns eyeglasses. He is completely dependent on the prejudices and fashions of his times, since he never gets to see or hear anything else. And what a person thinks on his own without being stimulated by the thoughts and experiences of other people is even in the best case rather paltry and monotonous. There are only a few enlightened people with a lucid mind and style and with good taste within a century. What has been preserved of their work belongs among the most precious possessions of mankind. We owe it to a few writers of antiquity (Plato, Aristotle, etc.) that the people in the Middle Ages could slowly extricate themselves from the superstitions and ignorance that had darkened life for more than half a millennium. Nothing is more needed to overcome the modernist's snobbishness." (Albert Einstein, 1954)
