A short answer to this question is, "We should embrace ideology insofar as it is productive and beneficial to our relationship with reality and with our communities."
If we embrace ideology to too great an extent, we will be inflexible. Our views will become too stiff to bend to the realities of experience and the complexity of the actual world we live in.
However, it has been pointed out above that ideology can be helpful in that a functional value-based world view can help us to navigate the many complexities that we commonly face.
Understanding that ideology is a simplification of perspective molded into a code, we can adhere to ideology without mistaking it for the "whole truth".
