It seems some thinkers have the opinion that having a strong system of subjective values and beliefs is a sign of weakness. I think this is because these people attempt to approach life itself with the same objecitivy they find so effective in argumentation and research. This is impossible because true objectivity would require an infinite number of viewpoints and we only have one and our interpretation of others'. Yet, despite the unattainability of truly objective thought our desire for it remains.
"I think, therefore I am". The truth about yourself is the only thing you can know to exist with relative objectivity, yet it is the first thing discarded by some who seek objective thought. The ironic result is that the person is thinking even less intelligently because they have thrown out their only solvable variable in the grand equation: themselves.
The assumption that one is thinking objectively is itself a belief, and possibly the only one that we can know to be false.
