I am somewhat immodestly quoting myself from an earlier thread but perhaps this too bears repeating . . . ?
1. Because of our reliance on language we feel a need to 'label' things . . . often with a single word. And yet that label will often hold a huge variety of meaning depending on the preconceptions, biases, life experience, knowledge etc of the interpreter. When we use a 'label', we use it only within the confines of our own variables and these can only be limiting to our understanding of others who use the same label . . . others who may have a very different interpretation.
2. Humans tend to come to "conclusions" based on current knowledge, yet often making little room for the yet "unknown". We can't stand a 'hung jury' but a definitive stance on a matter tends to close us off to the unknown, if and when it becomes knowable, simply because it is contrary to our definitive stance. This can be very limiting . . .
Many believe they are completely receptive to new knowledge, but are in reality "barrow-pushers" of thier definitive position and receptive only to that which reinforces it . . . committed JW's are a perfect example. Beware of labels . . . and be generous in allowing for the unknown . . . we don't always have to take an intransient definitive position in order to believe . . . nor is it weak or shameful to change what you believe.
May I also add that it appears to me that Morpheus was speaking in the context of the limiting nature of these factors i.e. fear, doubt, disbelief . . . not the freedom that critical thinking allows. This type of doubt is the one where the individual does not feel "free" to act on what he believes and this too is limiting.
It's not enough to simply be free of doubts and disbeliefs. A mind that clings to belief is still a mind that is not free; that is a mind that is bound to a set of thoughts because it identifies with those thoughts - that is not freedom. Freedom is freedom from everything, including beliefs.
Poppers . . . I believe my 'label' for this kind of freedom is 'Death'
