I've noticed that no matter how liberal or extreme I become, I will always find opposition. I guess it would be fare to say that I was full of it as well, as seen from an individual angle, outside of my own. I guess it all boils down to, who has the best answer. Even then, if I don't question it, I'm just as full it as they are... Lost thought...
If I must call out how full of it everyone else is, then I must include myself. It would only be fair, no?
Not all of the time. If you use that analogy, you have to factor in for bowel movements. So, I would say we are a mix of moments of clarity and moments where we experience a back up of waste products due to not completely digesting information we've consumed. There's usually a mix of truth and bs in any spiritual philosophy.
Yes, it's our nature. As a matter of fact we are ruled by our sub-conscious. Our consciousness only justifies what we do. The perfect example is spending some time with a narcissistic person. According to them, they are always right. They reinvent their memories to ensure they are remember themselves in good light. The rest of us are just narcissus to a lesser degree. I just made that crap up.
Anybody who is "ruled" by their subconscious while ignoring their utter consciousness as a whole, is obviously "full of it," as they say. This particular forum topic most likely didn't include cognitive constipation or did it?
