In the pursuit of truth, an open mind is essential. When one acknowledges that all conclusions are tentative, one grows better able to challenge one’s opinions with a more thoughtful consideration of the possible validity of new information. Many cultural indoctrinations, however, encourage close-minded acceptance of the day’s dogma. Complacency may set in, and the paradigms through which one tries to understand the world are outmoded by deeper insight, to the distress of those clinging to old certainties. It is important to be active in breaking this tendency. It does one no good to be set in one’s ways, and one may have a more positive effect on the world by remaining open to new perspectives. To quote George Bernard Shaw, “Progress is impossible without change; and those who cannot change their minds cannot change anything.” A being must be willing to perhaps let go of the conclusions of the past in order to adopt more informed perspectives in the present and steer more mindfully towards a better future.
