I think a humble attitude to what we can truly ever know is a good thing. I promote that. I fight the dogmas of mainstream everything on a daily basis. I fight the dogma of mainstream science mainly. For the very reason outlined. Beyond this I think we must try to be as broadly informed as we can. Be of critical thinking mind. Be a true sceptic of everything, especially institutions. Examine logic relationships within science and its claims. Examine all institutionalized knowledge and claims. Be able to unlearn what you were taught. Be self aware of your own preferred paradigm and bias. Realise that all is mind and we attract that which we give our attention. Understand that truth is elusive but worthy of persuing in life. It is most likely the only thing worth persuing in life. That and love.
