Rwahrens recently penned an article on this Blog addressing what he called real challenge for Democrats and “progressive voters” – should they support Obama for a 2nd term, or should they send a message to a party and president who is not being progressive enough. Rwahrens presented what seems a reasonable argument that Progressives should agree on one thing: “beating the Republican Party and preventing them from getting into office” For example he pragmatically cited the damage that a Republo-Conservative tide could effect which should override “every single other issue you may have.” It also makes reasonable arguments, including historical precedents such as what happened when moderates were beaten by ideological conservatives. But it is also true that some of the assumptions can be challenged. I’m not writing here to fight this specific battle, which is obviously an important one, but rather to briefly (very briefly) frame some of the problems that make it difficult to reach objective conclusions on such issues. The questions concerns conceptualization of truth and objectivity and why we think certain things (x, y, z) will happen if we have a or b. Well it is usually complex and there is a threefold mix of rational, empirical and pragmatic elements in all such arguments that make the pursuit of good judgment difficult.
All 3 elements (rational, empirical and pragmatic) are part of the humanist tradition, but the type of reasoning we call rational is probably a good place to start. The pre-Socratic Greeks, starting with Thales, gave us a styl

“ promoting reason and science as the most reliable methods for understanding the universe and improving the human condition. Informed by experience and inspired by compassion, we encourage the pursuit of knowledge, meaning, and responsible ethical codes…” http://www.secular.org/
Which brings me to the scientific-empirical side of reasoning and logic. We now know more about the limits of human rationality and reasoning. It is deeply flawed and subject to leveraging by all kinds of biases. Indeed the American Pragmatists like Peirce, James and Dewey, who built on Kant’s critique of reason (pure reason ends in irresolvable paradoxes), were all over this limitation in the late 19th and early 20th century. Humans reasoning, as given to us through the building blocks of our animal evolution, is in practice, often limited and not strictly logical. Our reasoning includes adaptive heuristics that offers quick and compelling judgments, which ignore details that are too hard to compute. Indeed cognitive studies have shown that much of thinking depends on emotion, and that people’s rationality is bounded by limitations of attention and memory. This means for example, that we find it difficult to employ all relevant facts. For one thing facts and asserted arguments are not passive, objective things. People are actively trying to make their case and using selective facts, shading issues and fuzzing up arguments all the time. We live in a dynamic mix of half truths and manufactured positions. We often have to rely on external fact checking because, to paraphrase Twain, much of what we are exposed to in the media just ain't so. This inability to handle all the uncertainly and complexity that we find in our culture means we focus on some details/facts and avoid or dismiss others. We are aware of this in debates on complex topics, but often in debate we aren’t sure of why reasonable arguments, based on empirical evidence, do so poorly in persuading others. Can’t we see the facts, for example, of what a Conservative administration has done (2000-2008) and just extend the inferences to current and future situations? Well yes, but mechanistically it requires lots of assumptions and long lines of reasoning that can be challenged along the way. It is an inexact science and subject to influence by the intents of the reasoner.

This view of our rational abilities is humbling. It further undermines the Enlightenment ideal of conscious, universal, and dispassionate reason based on logic. It even challenges an easy scientific formulation that empirical facts combined with reasoning gives us a privileged view of the world. This is possible, but it requires great discipline since we are attracted to compelling arguments that offer a good story (as previously posted on the Meme idea). Such narratives do make sense based on our experience, but these too are shaped by a non-logical process. To make sense of the world we inevitably see things from a particular point of view. This point of view includes the many experiences and biases accrued over our lives and is hardened into beliefs that serve our immediate needs. Beliefs and opinions are further shaped into belief systems by our cultural experience, exposure to stories and as member of political groups and parties. In most conversation these selective, easy to communicate and attention-getting, subjective experiences and judgments tend to be dominant over purely objective experiences.
