Re: Can we really
^ Perhaps you wanted to say that if you came across a concept without bias then to accept it on that basis, and if you came across a concept with bias to accept it on that basis, then through experience improve on ones stance in a fair manner.
To stay on the fence until we are certain is a fallacy of the agnostic
We should decide be it as per our bias or not and then to modify our stance as more 'light' is shed on the issue through time and experience.
So the answer being belief can be torn away from bias when our faculty of wisdom dominates our other faculties. courage, temperance and justice.
