I detest dogma; it always gets in the way of progress. But then again, that is its purpose: to preserve existing knowledge and to be skeptical of anything new or foreign. Dogma is useful when used to further a higher goal like the integrity of science. Science would lose all credibility if it routinely accepted new ideas as fact one day and then discredits them the next. But dogma is too often the result of petty or selfish agendas.
I guess I should clarify. I hate it when people are dogmatic for the sake of being dogmatic – when they go beyond rigorously testing your ideas to just impeding your way because they don’t like you or your ideas. This is when dogma no longer serves a higher purpose and becomes a weapon for personal attack.
You see it all the time, even among the most highly educated. It’s extremely disappointing to see otherwise respectable scientists duke it out like kids in a schoolyard. Yes, I know your life’s work might be in question, but if you are wrong, you are wrong. You are only delaying the inevitable; you might as well be gracious about it.
