Of course I will take responsibility for my mistake, my assumption, it is right there in the word: "atheist", a-theist, anti-theist, against theism. And though I am not a believer, my disinterest in belief does not define my self or my thoughts or more specifically, the way I choose to think things through. Nobody who likes the color red describes this preference as anti-green.
A causalist isn't as depressed by this seemingly hopeless understanding as one might expect. A causalist just accepts reality and looks for solutions that work with and are informed by it. If humans have great big thinking machines that are hard to hear above the ruckus and clatter of emotions, the challenge is to build cultural solutions that protect and automate higher order knowledge from the vagrancies of low level emotions. The playing field shifts with this shift in perspectives. Instead of looking for solutions within the arena of emotional thought (meditation, mood music, a harmonic convergence, global conciseness, etc.) the cuasalist, looks for solutions outside of the lizard brain, looks for solutions that accept the lizard brain but work to lessen its control over policy and society. A causalist looks to the infrastructure. A causalist has noticed that people act more constructive when their environment takes care of the simple needs of the lizard brain. A causalist has noticed that clean running water at every faucet, enough food, reasonable shelter, and reliable stability make people with the same lizard brain end up acting more like their grey matter ideas and less like a lizard. No amount of prayer or philosophy or yoga will yield the same productivity improvements and cultural growth as a reliable and supportive infrastructure.
Take the time to look at the statistics that compare a culture's confidence in its infrastructure and its per labor hour productivity or its crime rate. Then try to find a better predictor of a culture's ability to build towards greater and greater progress of knowledge and opportunity. Confidence doesn't build an infrastructure, infrastructure builds confidence. Those of us confident enough to see this hierarchy for what it is must work constantly and vigorously against the grain. We must build the infrastructure that will produce in tomorrow's masses the confidence we are lucky enough to feel today.
It is way way way cheaper to run clean water and nutritious food into every home than it is to deal with the chaos that ALWAYS results when people must live with the fear of thirst and hunger. Going to church for an hour a week isn't ever going to have the same effect on productivity and stability. Even the religious would surely rather pray for more interesting and complex goals than a bowl of rice and clear water.
Accepting the weird irrationality of the human thinking and emotional system doesn't mean that you have to be irrational about your acceptance of it or how you choose to go about building towards a better future.
