The worst offenders, I find, are Physicists who cannot follow a logical argument that is not full of mathematical formulae.
If physicists are the worst offenders, biologist are attempting to give them a good run for their money.
Although I can't hope to be able to make any conclusions about who is an authority worth believing when it comes to particle physics and the like, I can certainly tell you that the lack of being able to follow a progressive line of logical points, from simple to complex, without needing to gum up the works with unnecessary clutter is not the unique skill of physicists. Understanding the role of theories in evolution, and being able to map out how things came to be requires seeing a much bigger picture than most biologists seem to be able to discern. Evolutionary thought requires as much philosophy as it does science, but it seems the rare man who can combine the two in his brain.
Someday we may find the actual reason for that. My theory is that people who either enjoy, or are more capable of learning about things at the molecular level, are perhaps less interested, or less capable of seeing a field then they are the blades of grass. I know some people who are obviously quite knowledgeable about many biological functions-yet struggle grasping some of the most simple sentences and analogies truly blow their mind.
Sorry to say, cavediver and a few others here who have great interest in science appear to be these kinds of people to me-obviously smart guys and have a great grasp of math equations, but perhaps because their minds are so in tune to these numbers, there isn't a lot of room left in there for intellectual imagination.
Just one question which I admit to knowing little about- How does one believe in string theory, while acknowledging that in order to make sense of the numbers we must first create fictitious other dimensions of varying amounts to compensate for the discrepancies, as well as admitting that it is completely untestable? Isn't that much more philosophy than science? Or perhaps not philosophy, but at least fairy tale?
