9/28/2009: Cognitive LimitsOur cognitive limits in thinking about anything are severe. The human brain operates at a basic, local, human scale except that our capacity for double-scope blending allows us to understand vast conceptual networks by anchoring them in human-scale blends. The indispensability of human-scale blends is a strong constraint on thought. There are many aspects of our thinking about political and economic decision-making that should be universally accepted, such as that a self is variable, and that a self at any moment knows that it is subject to variation and takes defensive and offensive actions against its past and future versions. These basic truths from cognitive science are papered-over by classical economics, which assumes a constant self, in the form of a utility function. But a self is a complicated and dynamic outcome of complicated conceptual integration networks. . . .8/17/2009: The Scope of Human ThoughtBiologically, we resemble other animals, but mentally, we leave them in the dust. The scope of human thought is vast. Why are we so different? Animals—including us—live, think, and feel in the here and now. Living, thinking, and feeling are biological events, existing only in the present. When we think about the past or the future, or anything distant or outside the situation we inhabit, the thinking and feeling are not distant—they are right here, right now, present, confined to our local, human-scale situation, conducted through here-and-now biological systems. In this regard, we are like dogs, dolphins, corvids, chimpanzees. A human being may have been alive 10 years ago and may be alive 10 years hence, but our brain activity of 10 years ago or 10 years hence does not exist. The only systems for living, thinking, and feeling that human beings possess are run by their bodies here and now. . . . |
