I have found through my own experiences that the hardest thing in the world to do, especially in public, is to admit you are wrong or don't know something. The hunger to be ever-aware, always on top, dominates our emotional and instinctual selves. Through the advent of science, we have labeled consistency as truth and from that day forward we have been placing experiences, phenomenon, life, civilization, creatures, matter, people and so on into boxes whose identity is constructed by us. This makes the idea of not knowing something seem pretty daunting.
The problem that this poses on a society whose information comes from experts in science and scientific law, who know everything there is to know about one particular thing, is not only the lack of holistic approaches to problems, but also the incorporation of biases and agendas. Someone might know that a certain approach works for keeping pests away from your garden vegetables, but being an expert in pesticides does not make you an expert on pests.
Our species has become too centered on creating individuals who are experts in overly specific fields of study. I feel strongly that it is time to start removing ourselves from the over-specialization of our insatiable society and start awarding ourselves honorary degrees in generalism. I think it is time to become hobbyists in tribal knowledge. If you have illnesses or children with them, don't just let the doctor be the expert, teach yourself about healing using herbal remedies and food. If you like eating delicious meals, teach yourself to grow and cook. If you eat dairy products, get an animal and care for it, milk it, make cheese. Make clothing. A trouble tree in your yard? Pick up a book and learn proper axe technique. Build something from the wood.
Turn off the tv, step away from the computer, and download some free information and skill-sets from your arms and legs. Investigate deeply into the world of self sufficiency and learn to distrust anyone claiming to be an expert.
One of the most inspiring days of my life has come from openly admitting that there are things about this world I may never claim to know. Even within our educational systems we are rhythmically pressured into believing that learning equals knowing. For the most part, I would say, learning equals understanding and that knowing truly isn't that important. What is important in my life is what I can do with my two hands to care for myself, those I love, and this world.
