Analysis of Integrity

I was approached with a deep, simple, yet disturbing definition of the word integrity. Integrity is when Beliefs equal Actions. While I would love to describe myself as a man of integrity, by this definition I would be knowingly lying. Actions are easy enough to identify, but beliefs are not quite as straight forward. When does an opinion transform into a belief? Do your beliefs determine your actions or vice versa? I don't think there is a correct answer, and in fact find truth in both possibly conclusions. To a loyal vegan, I would find it hard to argue that their beliefs didn't directly influence their (unnecessary) herbivore actions. To a profiting entrepreneur, I would argue the opposite. In order to maintain the financial comfort their actions have provided them, it seems logical that they would mold their belief system to suit the ethics necessary to live that particular lifestyle. Despite being polar opposites, both of the above examples could be accurately described as having integrity. For myself, the dilemma is that my beliefs are not developed to the point where they have the power to dictate my actions. Instead, my actions are in a scary way predetermined. Watch this movie because it got rave reviews. Go to this college because it looks good on a resume. Where this cologne because the women love it. These are not actions based on belief but rather on mass persuasion. And enough mass persuasion creates mass belief, tailored to the norms of society. I am personally trapped halfway in this belief propaganda machine; my actions directly contradict my beliefs. How is this logical? My beliefs cater to the whole while my actions cater to myself. It's kind of like a Democrat trapped in a Republicans body. No matter how much I believe in the evils of greed, I find myself wanting more. Needing more. Taking more. It is the downfall of the human race. The invisible hand according to Adam Smith. The decision now becomes, do I change my actions or change my beliefs? Because I sure as hell need a little integrity.
