<div><br></div><div>Rationality is not some floating abstraction. Rationality is, fundamentally, applying reason to your context (all information, and the objective conditions) to reach the best decision by certain criteria. For beings like humans, the only purpose that using reason can have is to further one's life in some way. Humans must think in order to survive and thrive (civilization is built upon our ability to reason about things). So, what criteria must we use when applying the rules of logic? Well, the furtherance of our lives of course, physically, mentally, and socially. Physically, in terms of our health and length of life. Mentally, in terms of our desire to live and our enjoyment of life. And socially, in having a society which allows us to live. So being rational, for a human being, is all about using reason to make our lives better.</div>
<div><br></div><div>Humans have finite time and information, therefore in every problem we face we will have to settle for a non-ideal answer (that is, something less than the answer we would arrive at with perfect knowledge and infinite time/resources). Doing so, for example by simply picking what seems to be the best answer because there is no more time to think about it, is not being irrational. It is being perfectly rational. It would be blatantly irrational to stand in Publix for 10 hours, tablet pc out, researching all the academic research on the effect on health of various brands of peanut butter, building spreadsheets with cost-benefit analyses, etc. just so you can go home and eat a fluffernutter sandwich for what was originally going to be lunch, but would now at best be a late-night snack. That's not just irrational, it's bonkers. Indeed, outside the context of a simple game (like checkers, perhaps), the idealist standard of rationality, based on perfect knowledge and resources sufficient to track the entire range of possible consequences of an action, is impossible to achieve. No being will ever have perfect knowledge or infinite resources, and so no being can be perfect, in the sense of never making a non-ideal decision. But that doesn't mean that no being can be rational. Rationality isn't about perfection, it is about making the best decision to further one's life given all conditions, including concerns of time and relative importance to other goals, etc.</div>
<div><br></div><div>In short, Spock standing there pondering the question of which direction is the best way to jump out of the way of a Gorn trying to bite his head off is not being rational, it's being stupid.</div>
